Kwiat Round™

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 at 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® Round

We 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 Cushion™

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

Kwiat Oval™

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 Cut™

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

Kwiat Radiant™

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 AND TRANSPARENT

Every Kwiat Tiara diamond is cut from the rough stone by Kwiat and can be traced to its country of origin. This guarantees that the diamond is conflict free and sustainably and ethically mined.

BUILDING A BRILLIANT LEGACY

Kwiat is a family business with a heritage of service, quality, and integrity. Guided by these values, Kwiat has flourished, blossoming like the family name, which means “flower” in Polish.


In 1907, Sam Kwiat opened a diamond shop in New York City; he was joined by his son, David, in 1933. Today, Kwiat has grown to become a renowned brand led by David’s son, Lowell, and his grandsons, Greg, Cory, and Russell. Like their forebears, they have perfected the science and art of cutting diamonds. And they continue the tradition of trust and authority that Sam Kwiat established more than a century ago.
