Welcome to Of a Kind’s Fine Jewelry Oasis

121516 sr oak web14 11299 crop

As we prepared to launch the collections of four of our very favorite fine jewelry designers on the site—Anna Sheffield, Kathryn Bentley, Lauren Wolf, and Still House, for the win!—we realized that we wanted to do a much deeper dive into the world of carat and karat counts. (Or maybe we were just searching for even more excuses to look at shiny, faceted things? Who can say.) Either way, we present to you an opportunity to learn a little more about the precious things that we adorn ourselves with—or maybe just aspire to—from cinema’s best jewel heists to the purported powers of all those shiny gemstones. This way, when you splurge on a pair of knockout drop earrings or convince someone to buy you a stunning-as-they-come eternity band, you’ll feel like you’ve really, truly earned it.

Gem Glossary

We’re leaving no stone unturned.

Oak lauren wolf diagram final 001

Glossary dark diamonds

What It Is: Harder than any other diamond, it’s named after its resemblance to charcoal. Naturally occurring, or “true” versions, consist of a diamond that formed with a high percentage of carbon and graphite, which lends them a darker color. One can also be artificially made by heat-treating a low-quality white diamond.

Purported Powers: Supposedly it represents invincibility and strength—as well as potentially channel and enhance any psychic power ya might already have on hand. In Italian folklore, it was said to help reconciliation between couples.

Origins: Central Africa, Brazil.

Where You’ve Seen It: Legend has it the Black Orlov diamond, traced back to 19th century India, was cursed after it was stolen from a shrine in Pondicherry. Felicity Huffman nearly wore the same gem to the Oscars in 2006, but thought better of it. In other news: 2 Chainz name-dropped black diamonds in his song, “No Lie.”

Glossary whitediamond

What It Is: A colorless, clear stone made from compressed carbon—the world’s hardest naturally occurring substance and the most coveted gem in the world.

Purported Powers: It’s an obvious symbol of wealth, though colored versions have been giving the old standby a run for its money lately (har). The classic is said to bring a positive mentality and a purifying, enlightening capability to the wearer.

Origins: Russia, Botswana, Congo, Australia, South Africa, Canada.

Where You’ve Seen It: Engagement rings worldwide. Also, Elizabeth Taylor's infamous perfume and jewelry line (memorably spoofed by Rachel Dratch on 30 Rock).

Pictured Above: Five Cluster White Gold Celestine Band by Anna Sheffield

Glossary warmdiamond

What It Is: Any diamond, ranging in color from straw to brown or pink, can fall into one of these buckets. The more vivid the color, the more valuable the stone. It’s not actually pigmented—instead, nitrogen inclusions in the stone’s inner structure reflect light in a way that makes it appear shaded.

Purported Powers: A master healer, unifying mind and body. So, as good as yoga?

Origin: Australia

Where You’ve Seen It: The largest faceted diamond in the world is the brown Golden Jubilee Diamond, which was gifted to the King of Thailand to celebrate 50 years on the throne and weighs in at a monster 755.5 carats (um, those anniversary roses you got seem kinda lame now, huh?). Plus, J.Lo’s a master of the category—her 5.5 carat pink Harry Winston from the called-off Bennifer engagement is the stuff of legend.

Pictured Above: Champagne Diamond Pavé Pointe Studs by Anna Sheffield

Glossary tourmaline

What It Is: This semi-precious mineral can include elements like iron, potassium, or aluminum that give it a resemblance to granite. Considered an “electric stone” because it conveys a current, tourmaline is unique because it comes in various shades ranging from black to red to yellow to green, depending on which other minerals are present.

Purported Powers: Said to deliver soothing, healing powers, it’s been a favorite of shamans and medicine men around the world. Multicolored tourmalines are said to help bring internal balance—and who doesn’t need that?

Origins: Afghanistan, Pakistan, Burma, Namibia, Nigeria, Sri Lanka, Russia, America (Maine).

Where You’ve Seen It: Ben Franklin used it in his experiments (presumably the lightening rod one). Tourmaline first gained popularity in jewelry after a gemologist named George Kunz sold a green one to Tiffany & Co. in 1876.

Pictured Above: Tourmaline Organic Amulet Pendant by Kathryn Bentley

Glossary emerald

What It Is: A bright green gemstone consisting of a variety of beryl.

Purported Powers: According to ancient Egyptians, it’s good for fertility and rebirth. And, word on the street is that wearing it can combat aging—Aristotle also thought it helped the healing process.

Origins: Egypt, India, Austria, Zambia.

Where You’ve Seen It: The famous Chalk Emerald, originally weighing over 38 carats, was worn by Indian royalty in Baroda State before eventually being recut and set in a ring by Harry Winston that now sits in the Smithsonian—go visit it! Like many Egyptians, Cleopatra had a soft spot for emeralds in particular.

Pictured Above: Florentine Ring by Kathryn Bentley

Glossary lapis

What It Is: This deep blue semi-precious stone was first mined in Afghanistan as early as the 7th millennium, B.C. During the Renaissance, artists prized ground lapis as a pigment.

Purported Powers: In Buddhist thought, it symbolizes inner peace. It’s also been said to aid in wisdom, intellect, and truth.

Origins: Afghanistan, Pakistan, Russia, Chile.

Where You’ve Seen It: It's the source of the blue color in the iconic Vermeer painting Girl with the Pearl Earring. Whole stones made an appearance on King Tut’s mask, along with turquoise and colored glass. And in more modern celeb spottings, Amy Adams rocked a pair of lapis-lined chandelier earrings to the 2014 Oscars, ℅ Tiffany’s.

Pictured Above: Lapis Organic Amulet Pendant by Kathryn Bentley

Glossary turquoise

What It Is: The green-blue or sky-blue color of the opaque mineral comes in part from percentages of copper and aluminum. And heads up: Synthetic versions are common—spot them by their lack of natural variations.

Purported Powers: It’s said to strengthen the immune and respiratory systems and to be calming and help creativity.

Origins: America (Arizona and Nevada, mainly), Turkey, Iran, Egypt, Chile, Mexico, China

Where You’ve Seen It: All over the Southwest. Memorably worn by the likes of Georgia O'Keefe, turquoise also features prominently in Native American jewelry and can be found on amulets crafted by Aztec, Pueblo, Navajo, and Apache tribes. Turquoise was symbolic of fire for Aztec priests and even functioned as currency in ancient Central America. Oh, yeah—and Aidan Shaw couldn’t get enough of it.

Pictured Above: Turquoise Organic Amulet Pendant by Kathryn Bentley

Glossary sapphire

What It Is: How’s this for impressive: It’s precious stone known for its mesmerizing color and durability both. Sapphires are actually just the blue version of a stone called corundum, which is the same thing as a ruby—titanium and iron just lend them that cool ocean hue.

Purported Powers: According to ancient Persian folklore, the sapphire makes the sky blue with its reflection. It was also donned by royalty as a defense against harm and is a common symbol of victory. Also: mental clarity and focus (are you sensing a trend?).

Origins: Australia, Thailand, Kashmir, America.

Where You’ve Seen It:  Princess Diana’s much-discussed engagement ring, which now belongs to Duchess Kate Middleton. And maybe even more famously, The Heart of the Ocean, a made-up stone that plays an even bigger role in Titanic than Leo’s pouty face.

Pictured Above: Rainbow Eternity Band by Kathryn Bentley

Glossary pearl

What It Is: Unlike everything else we’ve talked about, this smooth, iridescent bead-like gem is not found in the ground, but rather in oysters and mussels. It’s created when something like a grain of sand is caught in a mollusk and becomes coated in the shell’s inner lining. Almost all pearls these days are cultivated, in either salt or fresh water.

Purported Powers: Pearls are an ancient symbol of purity and fidelity—and, since a great deal of luck is involved in finding naturally occurring ones, that too.

Origins: The Persian Gulf, South America, Asia, Australia.

Where You’ve Seen It: Where haven’t you seen it? Worn by Coco Chanel, Jackie O., Grace Kelly, Audrey Hepburn, and Marie Antoinette, pearls are iconic—basically shorthand for traditional sophistication. Modern jewelers are freeing them from sometimes-stuffy country-club vibes—and your faves like Michelle Obama are taking note.

Pictured Above: Reverse Attelage Ring by Anna Sheffield

Glossary quartz

What It Is: Striking but underappreciated until recently, the stone is transparent quartz with golden-hued threads running through made of minerals, called inclusions. Those streaks range from thin and sparse to dense and winding.

Purported Powers: So many! It may just stimulate creativity, promote self-discovery, and alleviate fear and anxiety. It’s also used in some meditation practices.

Origins: Brazil, India, Madagascar

Where You’ve Seen It: It’s a cornerstone of Spencer Pratt’s epic crystal collection—he’s got a wand made out of it! C’mon, you knew we couldn’t finish this without a Spencer shout-out, right?

Pictured Above: Eleonore Marquise Sapphire Earrings by Anna Sheffield

Designers On: Trends

Q: What jewelry looks are having a bit of a moment right now?

Anna Sheffield: “We’ve been seeing a lot of love for marquise-cut stones, which is wonderful because I use them a lot in my ceremonial and fine jewelry collections. They seemed to have fallen out of favor—I think mostly because of the style of jewelry they were most often used in—but I have an affinity for the shape and think it's very chic in modern jewelry designs.”


Urte Tylaite of Still House: “I’m noticing my customers are un-stacking their rings and un-layering their necklaces and instead just wearing one piece at a time but rotating frequently. I really enjoy that approach since it lets each jewelry piece stand out, no matter how delicate it is.”


Kathryn Bentley: “My collection is usually informed by personal obsessions over furniture, art, architecture, or historical design movements, so I try not to design to trends. That being said, I do think there is a general zeitgeist that motivates design. I am often surprised by the kind of collective consciousness that happens across design communities. For example, I’m currently obsessed with Deco architecture and design and think perhaps we will be seeing more of this.”

Talkin' Behind the Scenes with Anna Sheffield

Anna sheffield portrait

Ever wonder what it's like to sift through whole handfuls of diamonds (and maybe drop one on the floor)? Our founders asked gemstone queen Anna Sheffield about materials, costs, and all sorts of shininess on this very special episode of their podcast, A Few Things with Claire and Erica.

Designers On: Cleaning

Q: What are your favorite products for keeping jewelry looking its best?

Anna Sheffield: A soft polishing cloth is always good to have as long as you’re careful not to get too aggressive with it around delicate, prong-set stones. The cloths are best used for flat surfaces—they will keep bands looking tip-top and shiny without taking away any metal.”


Urte Tylaite of Still House:  “One of my essential cleaning tools at the studio is an ultrasonic cleaner. A professional-grade version costs way too much, no matter how many pieces of jewelry you own, but they do make affordable ones for home use as well.”


Kathryn Bentley: Polish your jewelry with a lint-free, 100% cotton cloth. If your piece is really grimy, you can try gentle brushing with lukewarm water, soap, and a soft toothbrush. I don't believe you need to use any harsh chemicals—they’re best left to the professionals.”

7 Jewel Heist Movies That Will Steal Your Affections

What’s the next best thing to owning diamonds? Watching cunning, crazy, romantic, ill-advised characters steal them, that’s what. Here, a handful of classic heist movies that we think are real gems.

The Asphalt Jungle (1950)

Basically a blueprint for every heist film that came after it, this 1950 film noir put the jewelry-stickup genre on the map. It takes place in a barren, unglamorous Midwestern city, where a robbery is just another job for a recently released criminal and his crew, but that doesn’t make it any less high-stakes. And: Marilyn Monroe in her breakout role (as the spitfire we now know her to be) makes it a must-see.

Sought-After Jewels: A tangle of pearl necklaces and diamond rings big enough to fatigue your finger. 

Small asphalt jungle

To Catch a Thief (1955)

If the on-screen chemistry between Cary Grant and Grace Kelly isn't enough of a draw in this Hitchcock whodunit, then maybe the sapphire dreamscape that is the South of France (Cannes, Nice, Cote d’Azur) will do the trick. Playing a former cat burglar trying to track down the culprit who's swiped his signature moves, Grant comes across an heiress (Kelly, dressed to the nines) and the sparks fly (see: a totally overblown fireworks sequence).  

Sought-After Jewels: A whole slew of glitz heirloom necklaces, rings, and bracelets.

Small catchathief2

Rififi (1955)

Where does a penniless, Communist-sympathizing American director go once he's blacklisted by McCarthyists? Why, France of course. Not a bad move, considering that Jules Dassin nabbed best director at Cannes for Rififi, his first film created in exile. A cult-favorite that's likely name-checked by any film buff worth their salt, the thriller tells the tale of an ex-con who masterminds a jewel caper with his crew, giving us a glimpse into a thrilling underworld and the early morning allure of Paris in the process. The crown jewel? A nail-biting 30-minute sequence of the robbery itself—during which no one says a word.

Sought-After Jewels: A safe's worth of the good stuff—including one distinctive diamond ring that eventually brings the whole thing toppling down. 

Small rififi 1955

The Pink Panther (1963)

Long before Beyoncé and Steve Martin tried to add some oomph to the remake, Peter Sellers dazzled as spectacularly dim-witted and klutzy Inspector Clouseau in the 1963 original. Vacationing in the Alps, an exotic princess with a priceless gem ("The Pink Panther") finds herself the object of attention. Among those hot on her heels: a playboy who moonlights as a jewel thief. Best-laid plans go haywire, but the Henry Mancini soundtrack and the animated pink panther (you know the one) will steer you right.

Sought-After Jewel: The fictional “Pink Panther” diamond, which has an imperfection that looks like a leaping cat.

Small pinkpanther

A Fish Called Wanda (1988)

Anyone with a passing affection for Monty Python, dark humor, and/or John Cleese, will find a lot to love in A Fish Called Wanda. It stars Cleese as a hapless lawyer and Jamie Lee Curtis, Kevin Kline, and Michael Palin as a trio of kooky bandits who double-cross each other at every turn. Tripped up by, well, mostly each other, they try to locate diamonds hidden by their ringleader. Two thumbs wayyyy up for the script, the cast, the everything.

Sought-After Jewels: A whole bunch of British diamonds. 

Small afishcalledwanda

Reservoir Dogs (1992)

Of course Quentin Tarantino’s debut film follows the ins and outs of a bungled (read: bloody) diamond heist. Orchestrated by a mobster, this botched robbery goes off the rails when a (recently acquainted) ragtag band of lowlifes discover a traitor might be in their midst. Hit men, including one Steve Buscemi (!), gripe over code names and deconstruct Madonna lyrics. Even in Tarantino’s pre-Pulp Fiction days, the cast is A+, the soundtrack solid, and the language salty. But for real: Stay away if blood makes you queasy.

Sought-After Jewels: In keeping with the plot, a mysterious cache of gems from the diamond exchange.

Small reservoirdogs sin 2

Flawless (1999)

Riding the trendy, early aughts wave of Ocean’s Eleven fervor, Hollywood gives us Michael Caine and Demi Moore in a heist set in the sixties, as seen via flashbacks. An unlikely pair from the get-go (he’s a charming, elderly janitor, she’s an undervalued exec battling endless sexism), the twosome finds a common enemy in the London diamond corporation that writes their paychecks. Props for Demi Moore’s distractingly good bouffant and the hyper-stylized set design.

Sought-After Jewels: Two tons worth of white, loose diamonds.

Small flawless

Just don't try these at home, eh?



Designers On: Avoiding Repairs

Q: How do you avoid broken chains, bent prongs, or any other fine jewelry mishaps?

Anna Sheffield: “You have to be aware of what you’re doing while wearing these pieces, especially gold, since it’s really soft and can get scratched and dented more easily than things like platinum. Things like hitting your hand on workout gear can damage your piece over time.”


Urte Tylaite of Still House: “We all get so excited when we acquire a new piece of fine jewelry that we want to wear our pieces all the time. It's always so hard to remember to take my jewelry off when doing home chores, especially if using harsh household cleaners. But! The more careful you are with our pieces, the longer they stay looking perfect, so it's worth it!”


Kathryn Bentley: “Most people think they can wear their jewelry all the time, but we highly recommend removing rings, necklaces, and earrings when exercising, showering, sleeping, cooking, cleaning, swimming, gardening, painting, and doing ceramics or any high-impact activities. Jewelry with stones should be checked by a jeweler on a regular basis.”

8 Famous Jewels Worth Knowing About

Listen, we like to keep things a little subtle with our jewelry over here, but that doesn’t mean we’re immune to a cartoon jaw-drop at the sight of some double-digit carats. So we thought it’d be appropriate to do a rundown of some of the most famous pieces of jewelry in existence—you know, just for ref.

Grace Kelly’s Cartier Engagement Ring

How do you convince one of the world’s biggest movie stars to leave Hollywood behind for you? Well, being the Prince of Monaco doesn’t hurt, but neither does presenting her with a 10.47 carat, emerald-cut Cartier ring. Though Princess Grace only lives on in classics like Rear Window, the ring’s still lending big-time glitz to the royal fam of the tiny country.


Princess Diana’s Engagement Ring

Like poufy sleeves and leggy looks, the colorful engagement ring trend can be (at least partially) traced back to Princess Di. Her engagement ring from Princes Charles is made up of 14 white diamonds encircling a whopping, 12-carat oval blue Ceylon sapphire, all set it 18-karat white gold—and now, of course, graces Kate Middleton’s left hand. The ring, which was made by the London jeweler Garrad, was chosen by Diana herself and wasn’t custom—a rarity for royals and something that was scoffed at at the time.  

Princess diana diamond engagement ring

The Hope Diamond

This one you know, right? Because it’s pretty dang famous. It was originally purchased in 1666 by a French jeweler (probably from India)—part of what makes it so special is its pale blue color. The rock weighs a huge 45.52 carats and was recut after being stolen in 1791. After going off the grid for 48 years, it turned up at a jewelry auction and was eventually scooped up by Harry Winston (you probably know that name too). It’s now on exhibition at the National Museum of Natural History in Washington, D.C.

Wallis Simpson’s Panther Bracelet

One of the most famous examples of Cartier’s signature ‘big cat’ series, the diamond and calibré-cut onyx bracelet is more notable for the way it bends to the wrist than the weight of the gems (but there’s still, uh, a lot of them). The piece was made for Wallis Simpson by the 170-year-old company after she was denied the chance to become Queen of England and King Edward III abdicated the throne for her—quite a consolation prize. In 2010, it sold for a record-breaking $4.5 million, the highest amount ever paid for a bracelet at the time.

Wallis simpson s panther bracelet3

The Elizabeth Taylor Diamond

This entire list could just be pieces from Elizabeth Taylor’s collection—but in the interest of fairness, we’ll just include the most famous ring. Originally named The Krupp Diamond, the 33.19 carat stone was renamed The Elizabeth Taylor Diamond after her which point it sold for $8.8 million bucks. Richard Burton originally gave it to her as an un-set stone aboard their yacht in 1968 (you know, as you do). Liz had it made into a ring, and the ginormous rectangular piece is an obvious precursor to massive celebrity engagement rings, like Beyoncé’s.

Krupp diamond 1

The Koh-I-Noor Diamond

You guessed it: more royals. The Koh-i-Noor (also spelled Kohinoor and Koh-i-nur) is a large, colourless diamond that was found in Andhra Pradesh, India, around the 13th Century. The stone floated between different leading families in the country before ending up in the possession of Queen Victoria in 1849. It’s now the centerpiece of the Queen Mother’s Crown, made by Garrad—it’s similar to the red version re-created for the coronation scene of The Crown.


L'Incomparable Diamond

The old ‘one man’s trash’ adage has never been more true than in the case of this 890 carat stone. A little girl discovered it playing in a pile of rejected mine rubble in the Democratic Republic of Congo in the eighties. The palm-sized diamond was sold by the girl’s uncle and set by jeweler Mouawad into a vine-like, rose gold and diamond necklace that was most recently valued at $55 million. Maybe be extra-careful the next time you’re gardening or something?

L incomparable diamond necklace2

Designers On: New Materials

Q: Which elements are you excited about?

Anna Sheffield: “My new obsession in colored stones is tsavorite, which is a bright green very similar to natural emerald, but it’s actually from the garnet family. You'll be seeing this stone—and likely a lot more emeralds as well—in the spring collections.”


Urte Tylaite of Still House: “I am a minimalist by nature, but I have been moving towards subtle imbalances in my designs like an off-center diamond or a slightly irregular triangle. I am thrilled to see how well my customers are responding to this new direction.”


Kathryn Bentley: “Our Deco collection features malachite, lapis, coral, and howlite stones inlaid in sterling silver with enamel. I love the combination of stones with the enamel.”

Designers On: Sustainable Sourcing

Q. What’s your philosophy on stone- and metal-sourcing ethics?

Doug Kramer, Retail Manager at Anna Sheffield: “For most pieces, we use recycled melee diamonds and recycled gold. In the circumstances when we do not use those materials, we only do business with vendors who we know source ethically. They are either heavily established in the trade or have the credentials to prove provenance.”


Kathryn Bentley: “We source stones responsibly, taking into consideration the environmental and ethical impacts when choosing suppliers.”

Urte Tylaite of Still House:The Gemological Institute of America, or GIA, offers a certification process for stones, which we offer with diamonds over a carat. It’s an expensive process, though, so it would be impossible to do for all of the very tiny stones we use. It’s really about finding suppliers you trust—I work with a few specific families in New York who travel in person to the mines and use the same stone-cutter every time, so they are there for every step and can vouch for the fact these aren’t blood diamonds.”
