In 1907, Sam Kwiat started in the diamond jewelry business. He never imagined that his passion would take hold for generations to come. Together with his son, David, they grew a small family shop into a diamond legacy. More than a century later, the Kwiat family continues to design and craft the most exquisite diamond jewelry.
We look forward to helping you find the perfect diamond design. Please let us know if you prefer to visit the Kwiat boutique at 773 Madison Avenue in New York City or speak with a boutique associate over the phone.

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.

Of the 4Cs of diamonds, carat weight is the most objective and easiest to understand. Quite simply, it refers to the weight of the diamond as measured in carats—the scale used for gemstones. At Kwiat, we cut diamonds for their beauty and not their weight. We work to find the ideal balance between carat weight and brilliance.
Color is measured on a GIA color scale, beginning at D with colorless and going through Z, which is very noticeable color. The diamond's shape and how it is set in a ring can also affect the way color is seen. At Kwiat, we only select diamonds in the colorless or nearly colorless range. Our round brilliant diamonds are in the D through J color grade range and fancy shape diamonds are in the D through I range.
Clarity is the number of inclusions, if any, within a diamond. Almost all diamonds contain some sort of natural inclusion - they occur when there is a disturbance in the process of a formation of a diamond over millions of years. A GIA clarity scale rates diamonds from flawless (FL) to included (I3 - heavy inclusions). Inclusions can be acceptable in a diamond, so long as they are not visible to the unaided eye.
All Kwiat diamonds are natural and conflict-free. Kwiat complies with the Kimberley Process, the United Nations-sponsored program designed to ensure that diamonds are not used by rebel forces to finance wars against legitimate governments.
