Choosing Diamond

4 Cs: Basic theory of a diamond

Understanding a diamond’s qualities is straightforward and simple.



Before purchasing a diamond, you should expect to review a copy of its certificate as proof that it has undergone an unbiased, professional examination. A diamond certificate, also called a diamond grading report, diamond dossier®, or diamond quality document, is a report created by a team of gemologists. The diamond is evaluated, measured, and scrutinized by trained eyes, a jeweler’s loupe, a microscope, and other industry tools. A complete certificate includes an analysis of the diamond’s dimensions, clarity, color, polish, symmetry, and other characteristics. Many round diamonds will also include a cut grade in its certificate.

All ANANTA  diamonds have been analyzed and graded by either the Gemological Institute of America (GIA) or the Hoge Raad voor Diamant (HRD). These two laboratories are among the most respected laboratories in the diamond industry, and are known for their consistency and unbiased diamond grading systems. Diamonds that are accompanied by these grading reports are the most highly valued in the industry.

Rapaport Price List

The Rapaport list is considered the primary source of diamond price information and intended for use in all situations in the diamond market. Once the 4C’s are established (color, clarity, cut and carat) as with certified diamonds, the list serves as the starting point for establishing prices. The Rapaport Diamond Report is a price guide and doesn’t give the absolute actual selling price of a diamond. So the prices on the Rapaport list are asking prices used as the starting point for negotiations.

Every shape or size sells at different discounts. Some shapes or sizes are not discounted at all. The Rapaport Diamond list does not take into consideration many other factors, including details about the cut (proportion and symmetry and polish) as well as other quality factors like fluorescence, which can raise or lower the price of a diamond drastically. The list is published every month and all prices are in ’00 USD per carat.
