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.

Ashoka Diamond 2021

THE ASHOKA® DIAMOND

A trademarked cut with fiery brilliance, available only at Kwiat in the U.S.

SHOP THE COLLECTION

A BRILLIANT ARRANGEMENT

ASHOKA is a trademarked diamond cut that is as distinctive as it is beautiful. The unique arrangement of 62 facets — the most consistent and symmetric of all fancy shape diamonds —creates a dazzling prismatic effect, giving ASHOKA its fiery brilliance.

A SIZABLE DIFFERENCE

The unique faceting pattern of the ASHOKA cut reveals a bigger and brighter diamond that appears 1-2 color grades higher than its GIA grading report, and 30%-50% larger than other diamonds of the same carat weight.

CONSISTENTLY BEAUTIFUL

It takes a special diamond to create an ASHOKA — fewer than 1% of rough diamonds meet the exacting standards. The process is demanding — it can take up to six months of meticulous work to cut an ASHOKA. The result: consistent stones of exceptional beauty, perfect for eternity bands, line bracelets, and other designs that require diamonds of equal size and symmetry.
