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.

The Fred Leighton Round Diamond


THE FRED LEIGHTON ROUND® DIAMOND

ANTIQUE INSPIRATION, MODERN BRILLIANCE

THE OLD EUROPEAN CUT, PERFECTED

THE OLD EUROPEAN CUT, PERFECTED

First developed in the 1890s, the old European diamond cut was the precursor to what we know today as the round brilliant diamond. At the time, diamonds were cut by hand. The result was stones that were not necessarily precise, but romantic and charismatic, with large facets that glimmered in candlelight.

By the 1930s, advanced technology led to the uniform faceting and updated proportions of the modern round brilliant diamond and many older stones were re-cut in the modern style. That’s why it can be difficult to find a beautifully cut old European diamond these days, especially in the colorless and near colorless range. And that’s why we created the Fred Leighton Round diamond—a perfected old European cut for discerning jewelry lovers who yearn for the understated elegance of an antique stone at the highest quality.

The Fred Leighton Round Diamond

HISTORY, EVOLVED

At Kwiat, we understand and love the old European cut. After all, when Sam Kwiat founded this business in 1907, it was the latest and greatest diamond cut available. We’ve spent the past century studying every angle and facet of the old European cut, and now we’ve perfected it, merging its classic elegance and unique character with our modern standards of precision diamond cutting.

We call it the Fred Leighton Round in honor of the renowned house of antique jewels that is a part of the Kwiat family. We say it’s “perfected” because unlike many antique diamonds, it has a consistently round shape; excellent polish and symmetry; a larger table for a more brilliant effect; a smaller, more refined culet; and precise dimensions that make it look bigger and brighter.

This is a diamond that captivates with a unique luster and inner light. We think Sam Kwiat would be proud.
