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.

Learn about diamond sizes

A Carat is the measurement of weight for diamonds. A carat is subdivided into 100 points, allowing greater precision in measuring to the hundredth decimal place – a .50-carat diamond may also be referred to as 50 points.

 

Carat weight does not always determine how large a diamond looks. The size appearance is most influenced by how a diamond is cut.

If a stone has too high a depth percentage – the ratio of its depth to its diameter – it carries more weight in its height, which does not add to its size appearance.

Carat weight impacts more than just size appearance, it also impacts pricing. The cost per carat for a diamond under 1 carat is less than the cost per carat for a stone 1 – 1.99 carats.

And the per carat cost of a diamond 2 – 2.99 carats is more still. And so on. As such, if all other variables are equal, you are much better off buying a 1.99 carat stone than one that weighs 2.01.

Kwiat Tiara® diamonds have a larger visual appearance when compared to other diamonds of the same carat weight due to our slight emphasis on diameter over depth.

Learn about diamond colors

Diamonds may contain small traces of color within the crystal structure, often tints of yellow or brown. Differences in color are subtle and often difficult to see by an untrained eye. Even an expert will have difficulty gauging subtle color differences without a point of comparison.

 

To illustrate this point, if you are sitting at a desk right now, look at a sheet of white paper. It probably looks very white when viewed in isolation. Now compare it to another sheet of white paper from somewhere else, maybe a business card or a notebook.

You’ll notice that while both sheets appear quite white on their own, when compared to each other one will appear whiter and possibly brighter. The same is true for diamonds. The lighter their tint, the rarer the diamond.

Learn about diamond clarity

The clarity of a diamond refers to the presence of internal inclusions, or flaws, occurring naturally within the crystal structure. Almost all diamonds have inclusions, but in higher quality stones they are not visible to the naked eye or under low power magnification. The greater the clarity of a diamond, the more rare it is.
