The four "C"s classify the value of diamonds. Every diamond's price, rarity and beauty are determined by the combination of cut, color, clarity, and carat weight.

Cut
Diamond CutCut describes the proportions and angles of a diamond. Many people confuse cut with the shape of a diamond. Although nature determines the other three characteristics, it takes a master diamond cutter to reveal a diamond's true beauty. Diamonds are available in various shapes, including round, square, pear, heart, marquise and oval, but cut refers to the angles and proportions of a diamond.

A well-cut diamond reflects light from one mirror-like facet to another and projects the light through top of the stone. The result is a fiery and brilliant display. Diamonds that are cut too deep or too shallow leak light through the side or the bottom, resulting in a lackluster appearance and diminished value.

Color
White-colored diamonds remain the most popular, even though diamonds are found in a kaleidoscope of colors. Diamonds are graded on a color-scale implemented by the Gemologist Institute of America (GIA), which ranges from D, which is colorless, to Z. Color differences can be so subtle that diamond colors are graded under controlled lighting conditions and are compared to a master set for accuracy. While truly colorless diamonds, graded D, are treasured for their rarity, diamond color preference is ultimately a very personal taste. Ask us to show you an array of color grades next to each other to help you determine your color preference.

Clarity
Nature ensures that each diamond is as individual as the person who wears it. Naturally occurring inclusions such as minerals or fractures are identifying characteristics created while diamonds are formed in the earth. We use magnification to view diamonds at 10x their actual size so these inclusions are more easily seen. Inclusions are measured on a scale of perfection, known as clarity, whihc was established by GIA. The greater a diamond's clarity, the more rare and valuable it is. An inclusion in the middle or top of a diamond could impact the dispersion of light, making it less brilliant.


Clarity Scale

Carat Weight
Carat is a diamond's measure in weight. ONe full carat is equal to 100 points. 1 3/4 carat diamond is the same as 75 points. Since larger diamonds are found less frequently in nature, a one carat diamond will cost more than twice a 1/2 carat diamond (assuming that all other characteristics remain constant). The cut and the mounting can make a diamond appear larger than its actual weight. We will help you find the right diamond and mounting to optimize its beauty.
