  • KWIAT ROUND

    The most brilliant round diamond in the world. 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.

  • 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 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 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.

  • 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.

  • ONLY AT KWIAT

    Kwiat Tiara Diamonds — seven 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.
