Diamonds can be found in a range of price—and you're certain to find one within the Diamond Quality Pyramid that suits your taste and what you plan to spend. If you're about to buy a Diamond Engagement Ring, you may want to consider spending the commonly accepted guideline of two months’ salary. But it's up to you to settle on a diamond that will truly represent your deepest emotions and the promise for the future you will share.
Cut - Refers to the angles and proportions of a diamond.
Based on scientific formulas, a well-cut diamond will internally reflect light from one mirror-like facet to another and disperse and reflect it through the top of the stone. This results in a display of brilliance and fire, thereby placing well-cut diamonds higher on the Diamond Quality Pyramid than deep or shallow-cut diamonds. Diamonds that are cut too deep or too shallow lose or leak light through the side or bottom, resulting in less brilliance and ultimately, value.
Cut also refers to shape round, square, pear, or heart for example. Since a round diamond is symmetrical and capable of reflecting nearly all the light that enters, it is the most brilliant of all diamond shapes and follows specific proportional guidelines. Ask a jeweler to find out more about these guidelines.
Non-round shapes, also known as fancy shapes, will have their own guidelines to be considered well-cut.
Color - Refers to the degree to which a diamond is colorless.
Diamonds range in color from icy winter whites to warm summer whites. Diamonds are graded on a color scale established by the Gemological Institute of America (GIA) which ranges from D (colorless) to Z.
Warmer colored diamonds (K–Z) are particularly desirable when set in yellow gold. Icy winter whites (D–J) look stunning set in white gold or platinum.
Color differences are very subtle and it is very difficult to see the difference between, say, an E and an F. Therefore, colors are graded under controlled lighting conditions and are compared to a master set for accuracy.
Truly colorless stones, graded D, treasured for their rarity, are highest on the Diamond Quality Pyramid. Color, however, ultimately comes down to personal taste. Ask a jeweler to show you a variety of color grades next to one another to help you determine your color preference.
Clarity - Refers to the presence of inclusions in a diamond.
Inclusions are natural identifying characteristics such as minerals or fractures, appearing while diamonds are formed in the earth. They may look like tiny crystals, clouds or feathers.
To view inclusions, jewelers use a magnifying loupe. This tool allows jewelers to see a diamond at 10x its actual size so that inclusions are easier to see. The position of inclusions can affect the value of a diamo nd. There are very few flawless diamonds found in nature, thus these diamonds are much more valuable.
Inclusions are ranked on a scale of perfection, known as clarity, which was established by the Gemological Institute of America (GIA). The clarity scale, ranging from F (Flawless) to Included (I), is based on the visibility of inclusions at a magnification of 10x.
Some inclusions can be hidden by a mounting, thus having little effect on the beauty of a diamond. An inclusion in the middle or top of a diamond could impact the dispersion of light, sometimes making the diamond less brilliant.
The greater a diamond's clarity, the more brilliant, valuable and rare it is—and the higher it is on the Diamond Quality Pyramid.
Carat - Refers to the weight of a diamond
Carat is often confused with size even though it is actually a measure of weight. One carat is equivalent to 200 milligrams. One carat can also be divided into 100 “points.” A .75 carat diamond is the same as a 75-points or 3/4 carat diamond.
A 1-carat diamond costs exactly twice the price of a half-carat diamond, right? Wrong! Since larger diamonds are found less frequently in nature, they are placed at rarer levels of the Diamond Quality Pyramid. Hence, a 1-carat diamond will cost more than twice a 1/2-carat diamond (assuming color, clarity and cut remain constant).
Cut and mounting can make a diamond appear larger (or smaller) than its actual weight. So shop around and talk to your jeweler to find the right diamond and setting to optimize the beauty of your stone.
