Kwiat Tiara Diamonds

Your Mine to Shine journey will culminate in the creation of a Kwiat Tiara Diamond. Informed by more than a century of diamond cutting expertise, Kwiat has created a collection of iconic shapes, cut to perfect standards and absolutely consistent every time.

Each cut reveals the maximum brilliance and size appearance for its weight... which means your diamond will always look bigger and brighter.

Kwiat RoundTM

A whiter, brighter, and larger looking round diamond, cut to the world’s highest standards. Simply brilliant.

ASHOKA®

This remarkable stone is available in the U.S. only from Kwiat. Its unique faceting pattern gives it a dazzling prismatic effect and makes it appear 30% to 50% larger than other diamonds of the same carat weight.

Fred Leighton RoundTM

Kwiat evolved a beloved cut from the 1890s, using modern technology to create consistent dimensions that make the diamond look bigger and brighter. It has all the charm of an antique, and all the precision of a contemporary cut.

Kwiat CushionTM

The cushion cut has been adored for centuries, but it’s difficult to find a well-cut one. That’s why Kwiat created Kwiat Cushion — a true brilliant cut with more sparkle and fire.

Kwiat OvalTM

Oval diamonds have an elongated silhouette that makes them appear larger than their carat weight. Kwiat Oval surpasses the typical, with a perfect shape, ideal length-to-width ratio, and a unique faceting pattern.

Kwiat Emerald CutTM

Popularized during the Art Deco era, the emerald cut has clean lines and parallel step cut facets that create a “hall of mirrors” effect. Kwiat improved on the classic to create a modern emerald cut with pure brightness and fire.

Kwiat RadiantTM

Radiant cuts are for those who love a diamond with a rectangular shape and more sparkle. Kwiat Radiant offers the maximum brilliance, with a unique combination of facets that creates pure brightness throughout the diamond.

RESPONSIBLE & TRANSPARENT

Every Kwiat Tiara Diamond can be traced to its country of origin. This guarantees that your diamond is conflict free, sustainably and ethically mined, and making a positive social impact in the region.

When you choose a Kwiat engagement ring, you are also supporting charity: water, an organization that provides clean water to people around the world. Every diamond ring sold provides water for an entire family.

THE JOURNEY FROM ROUGH TO RING

A look at the four steps that transform a rough diamond into an extraordinary ring that celebrates your love.

Step 1

Choose Your Rough Diamond

We’ll help you choose an uncut stone that will beautifully yield the diamond shape you desire. It will be from a known country of origin, ensuring it is conflict free and ethically mined.

Step 2

Cut to Perfection

Thanks to more than a century of experience, Kwiat diamonds are cut to the world’s highest standards. We are the only jeweler in our area to offer exclusive access to Kwiat Tiara Diamonds, the brand’s collection of perfectly cut iconic shapes.

Step 3

Design Your Ring

We’ll guide you through the design process as you choose the details that will make your ring unique. Our designers will get to work on a 3-D rendering that shows your ring from every angle. Request any changes you’d like — we’re not happy until you are.

Step 4

Crafted for You

Master artisans in their New York City workshop will handcraft your setting in platinum or 18K gold, per your specifications, and mount your perfectly cut diamond. The final result: a stunning, one-of-a-kind ring with unparalleled beauty and brilliance.

Your Diamond Journey

Whether you select a rough diamond, a polished stone or a completed ring, you will have the opportunity to witness the history of your diamond as it transforms into your unique engagement ring. When you choose Mine to Shine, you can expect a luxury bespoke experience, complete with regular video updates of your diamond's progress.

Your finished engagement ring will arrive in a Mine to Shine keepsake jewelry box, which includes a Kwiat Tiara Diamond Report and certificate of Authenticity for your stone, along with QR code leading to the full video of your diamond's journey.

A Legacy of Trust

Founded in New York City in 1907 and guided by a heritage of service, quality, and integrity, Kwiat has grown to become a renowned brand. Now in its fourth generation, the Kwiat family has perfected the science and art of cutting diamonds, continuing the tradition of trust and authority established more than a century ago.
