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.

Kwiat + Pencils of Promise


At Kwiat, we believe we have an obligation to make the world better. This holiday season, you can help us as we donate proceeds to Pencils of Promise, a non-profit organization that creates schools and programs globally with the common goal of education for all kids.

About Pencils of Promise

250 million children can’t read, even after several years in school, which translates into health and sanitation issues, gender inequality, economic instability, and a loss of $129 billion per year.

Pencils of Promise was founded in 2008 to increase education outcomes by building safe schools, supporting teachers with innovative resources, and providing students with health programming.
