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.

My name is Greg Kwiat, and I want to help you learn everything you need to know to buy a diamond. I’d like to introduce you to the Kwiat Emerald Cut, the most extraordinary emerald cut diamond in the world. Let’s explore what makes the Kwiat Emerald Cut exceptional and how we have perfected the art of cutting this classic shape. Emerald Cut diamonds are rectangular in shape with cut corners. They’re faceted with a step-cut pattern, a series of parallel facets on the top and bottom. This faceting gives them a more subdued brilliance with less flash and sparkle than other shapes. Because of this, emerald cut diamonds appeal to those who prefer an understated elegance. When worn in a ring, the rectangular shape can seem to elongate the finger and will often look larger than other shapes. The earliest example of the emerald cut shape traces back over five centuries to the 1500s. Gem cutters working on green emeralds found that this rectangular style of cutting was an easier and safer way to shape the stone. And it’s from there that the emerald-cut diamond shape ultimately got its name. The emerald-cut diamond rose to great popularity during the Art Deco period of the 1920s. The geometric form and clean lines were the perfect match for the design esthetic of the era, and they’ve remained popular ever since. The engagement diamond of choice for many jewelry lovers and celebrities. With over 100 years of diamond cutting skill and experience, we have created the Kwiat Emerald Cut, perfectly cut and extraordinarily bright. The Kwiat Emerald Cut is the ideal rectangular shape, not too long and not too short. It has distinctive and elegant cut corners. It’s perfectly cut and faceted with excellent polish and excellent symmetry, a rarity in stones of this shape. And because of our incredibly precise standards, the Kwiat Emeral Cut is pure brightness and fire throughout the stone with no extinction or dark spot. To truly understand why the Kwiat Emerald Cut is so exceptional, it helps to compare it to lesser quality emerald cuts that other jewelers cut and sell. There are two primary problems when it comes to subpar emerald cuts. The first is that the shape of many emerald cuts is too short or too long. The second issue is that the faceting pattern is often poorly done, leading to darkness or a general lack of brilliance. Let’s start with the shape of the diamond itself. The perfect emerald cut diamond will be a beautiful rectangle with properly proportioned cut corners. When speaking about the shape of an emerald diamond-cut diamond, we refer to the length to width ratio, which is calculated by dividing the millimeter length of the diamond by its millimeter width. If the diamond is cut too long, it becomes too skinny and looks imbalanced when set in a ring. The higher the ratio, the more elongated the diamond is, and length to width ratios over 1.5, indicate that a stone is too elongated relative to the ideal shape. If the diamond is cut too short, it has a less attractive, stubby appearance. Length to width ratios under 1.35 typically indicate a stone that is shorter than the ideal shape. The closer the ratio gets to 1.0, the closer a diamond is to a square shape. Shapes that tend to the square side typically carry excess weight on the underside of the stone where it does not add to the visual size appearance, causing the diamond to appear smaller. Dimonds that are outside of the ideal shape range typically sell at discounted prices. By comparison, Kwiat emerald cuts are always cut to the perfect rectangular shape in very strict length to width ratio ranges, never too long and never too short. Another major difference between emerald cut diamonds is the quality of the cut. In diamonds, cut is all about the angles, proportions, and facets. And as with all shapes, the cut quality of an emerald cut is the critical element that will determine its beauty. When an emerald cut is well-cut, the diamond will be bright throughout the entire stone and exhibit a great degree of fire and scintillation. The biggest issue with most emerald cut diamonds is they are not well-cut, and as a result, lack brilliance and life. Poorly-cut emerald cuts will typically exhibit extinction, which is a diamond term used to describe dark spots. This lack of light reflection occurs when light enters the diamond but fails to return to the eye, which leads to a dull and lifeless appearance. The Kwiat emerald cut is perfectly cut with excellent polish and excellent symmetry, and the result is pure brightness and fire throughout the entire diamond. At Kwiat, all of our diamonds are cut to our rigorous technical and quality standards. With more than 100 years of diamond cutting experience, we make certain that every diamond in every shape is cut to be the most beautiful that it can be. The Kwiat emerald cut is the most beautiful and perfectly cut emerald cut diamond in the world.
