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.
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.
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.
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.

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.
The ASHOKA is a trademarked diamond cut that is as distinctive as it is beautiful. A unique arrangement of 62 facets creates a dazzling prismatic effect, giving the ASHOKA its fiery brilliance.
Our exclusive round brilliant diamond exceeds the GIA’s standards, with a superior cut and a diameter that is as wide as possible. The result: a Kwiat Round diamond looks bigger and brighter than others of comparable weight.
Our perfected version of an old European diamond has a consistent shape, precise dimensions, excellent polish and symmetry, a larger table, and a smaller culet. These considered updates retain the romance of an antique cut while making it look bigger and brighter.
