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.

Vintage Style Engagement Ring with a Marquise Diamond and Sapphire Halo in Platinum - Kwiat

THE Bridal COLLECTION

Vintage Style Engagement Ring with a Marquise Diamond and Sapphire Halo

STYLE# F-29700SM-0-DIASAP-PLAT

Natural diamonds, ethically sourced, conflict free

Inspired by heirlooms from our archives, this ring features antique details crafted with today’s advanced techniques. A marquise-cut diamond is set in a milgrain bezel and haloed by calibré-cut sapphires and round brilliant diamonds above a filigree openwork gallery. Like all Kwiat diamonds and gemstones, these are cut to the world’s highest standards, exceeding even those of the GIA. Master designers and craftspeople created this platinum engagement ring to be open and airy, which allows maximum light to enter the diamonds, enhancing their brilliance.
