Diamond Size
Diamond Carat
Carat is often the first thing to come to mind when thinking about a diamond’s size. Size and carat weight are closely related but there are other factors in a diamond’s appearance. Cut and shape also play a role in whether the diamond appears visually larger or smaller than its actual carat weight.
Kwiat Standards
A properly cut diamond will not have too much weight in hidden areas. The added weight increases the cost without giving the diamond a larger appearance. At Kwiat, we cut our diamonds to keep the carat weight in the right places. Each gem has the widest possible diameter to appear larger than other diamonds of comparable carat weight. And because of their superior cut, our diamonds will appear whiter than their GIA color grade. We call this the Kwiat Tiara® Cut.

Diamond Color and Clarity
Diamond Color
Diamonds are rated on a color scale developed by the GIA, the world’s premier diamond grading nonprofit. The color grading system is based on the alphabet, beginning with the letter D and running all the way through Z. A grade of D is the best possible grade a diamond can receive, which translates to an absence of color. Diamonds with this grade tend to be the most rare and valuable.
Diamond Clarity
Clarity refers to the presence of imperfections, known as inclusions, in the crystal structure of the diamond. Nearly all diamonds contain some sort of inclusion, as they are part of a diamond’s characteristics and structure. An inclusion within a diamond is natural, and on the higher end of the clarity scale, does not take away from its beauty.

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™
With an elegant, elongated silhouette, perfect outline, beveled edges, and rounded corners, the Kwiat Cushion is a true brilliant cut with more sparkle and fire. And, unlike most cushions, it looks bigger than a round brilliant diamond of the same 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 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.

“I can’t stop smiling at the sparkle.”
Megan the concierge and her team were so helpful throughout our engagement ring selection process. They explained what made each cut so special and eventually we landed on a Kwiat cushion cut. Not only is it a little bit different from the usual shapes I see, but I can’t stop smiling at the sparkle. It’s just perfect and I couldn’t be happier.

“Thank you for making it so easy.”
Megan and the Kwiat family were amazing as I was planning the proposal to my now fiancée. I knew what she wanted (her hints were less than subtle!) but knowing it was being created in NYC where we both met, made it so much more meaningful and I even had the opportunity to get a sneak peek during the process. Thank you for making it so easy.

“She loved it!”
I wanted to gift my wife something after the birth of our first child but wasn’t sure what. As a new dad in the midst of the pandemic, I didn’t want to take any chances, so set up a virtual appointment with Kwiat. I don’t think the experience could have been much better had I been there in person as they had done so much preparation for our call. Making the decision was the hardest part, but I was assured that if she didn’t like it we could return it. That wasn’t something we needed to worry about. She loved it! Thank you Kwiat for always making me look good!

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.
