A diamond’s beauty, rarity and value is determined by its cut, color, clarity and carat, known as the 4Cs. Nature hands us a stone with adistinct color, clarity and carat. It is the remarkable skills of our master craftsmen that define the diamond’s cut.

Every stone we select must meet the strict standards we set over the past century. Only the finest rough diamond crystals, with a high color and clarity grade, will do. Stones are cut with precision and care to unlock the brilliance within.

Diamond Cut

Cut is by far the most important character of a diamond. Even at the best color and clarity grades, a poorly cut stone will appear dull and lifeless, while a well-cut stone will sparkle bright. Three factors contribute to a diamond’s brilliance: brightness, fire and scintillation. To achieve these factors, the GIA, the world’s premier diamond grading nonprofit, released formulas with combinations for crafting the most brilliant round diamonds.

Trading off on cut and selecting anything less than excellent on the GIA cut scale is a mistake. To understand the 4Cs and its relation to cut is to understand why you should never settle for less than perfection.

At Kwiat, we understand that the cut is the most important “C”. It is why our standards for cutting a diamond are the strictest in the world. All Kwiat round diamonds receive GIA grades of Excellent but not all Excellent diamonds are good enough to become a Kwiat diamond. Our diamonds fall within a smaller subset of GIA Excellent diamonds to capture the beauty and brilliance of how a diamond should appear. We call this the Kwiat Tiara® Cut.


diamond color

Color is the presence of yellow visible within a diamond. As a diamond forms underground, nature allows nitrogen molecules into the carbon structure, giving it a yellowish tint. The more nitrogen within a diamond, the more yellow it will appear.

Color is measured on a GIA color scale, beginning at D with colorless and going through Z, which is very noticeable color. The difference between one grade and the next on the scale is visually minimal. Select a diamond that is in the colorless or the near colorless range for the best value, keeping in mind that diamond shape and the setting can affect the way the color is seen.

At Kwiat, we adhere to the strictest standards and 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.


diamond clarity

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 to included (heavy inclusions). Flawless diamonds are crystal clear inside and out, without any inclusions, and are super rare. At the other end of the range is included-3, with extremely evident inclusions. Inclusions are fine, so long as they are not visible to the naked eye.

Some shapes such as asscher and emerald cuts show inclusions rather easily and should have a higher clarity grade. Brilliants such as the round and marquise can have lower grades since they show inclusions less readily.

At Kwiat, we only select Flawless to Very Slightly Included, with the rare exception of SI, when the inclusion is not visible to the naked eye. Our strict standards only allow for diamonds that appear visually clean to the unaided eye. If there are any visible imperfections, we will not use the stone in any of our jewelry. Balance clarity with color and carat to find what works for you.

Kwiat Tiara® Cut Diamonds

A diamond’s cut is its most important attribute. Over the years, we have refined our craftsmanship to an art form and created the most beautifully cut round diamond in the world. Every Kwiat Tiara® Cut Diamond appears larger than other diamonds of the same carat weight, while emphasizing maximum brilliance.

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. A larger carat diamond may not necessarily look bigger if it receives a poor cut. A larger carat is only worth it if it adds to the beauty and visual size appearance of the stone.

At Kwiat, we cut diamonds for their beauty and not their weight. We assess a stone’s potential and work to find the ideal balance between carat weight and brilliance. Our craftsmen have mastered the art of cutting a diamond to appear bigger than its actual size, maximizing each stone’s beauty.
