How can two near-identical diamonds—the same color, clarity, cut and carat weight—look the same online, but vary so much in cost? Both diamonds are certified by the same lab, but one is priced higher.  Is buying the cheaper stone the best option?

We hear these questions regularly, especially from men purchasing their first diamonds. The internet has made searching for diamonds more complicated, not easier. With online diamond databases, shoppers now have access to thousands of stones within their criteria, and the options can be overwhelming.  Some retailers and shoppers approach diamonds as a commodity, and since no two diamonds are the same, commoditization is truly not possible.

The key is to find the best value/quality relationship. Not all aspects of individual diamonds are spelled out in the certificate. The less expensive stone may have integrity issues or the more expensive diamond maybe overpriced.

The value of a diamond is based on the gemological characteristics of the stone, reaching beyond the basic 4C’s of diamond grading. At Gemological Trading Corporation, we have two GIA Graduate Gemologists on staff, and they analyze the finer details of each diamond, ensuring value beyond color, clarity, cut and carat weight. They scrutinize the inclusion type, size and location, as well as girdle thickness, cut proportions and fluorescence. Gemology makes the difference between buying an average stone and purchasing an exceptional diamond.

The GIA Graduate Gemologist degree is the most prestigious credential in the industry, and having two staff members to evaluate diamonds is a luxury few jewelers have.  The majority of fine jewelry stores do not have GIA Graduate Gemologists on staff. At Gemological Trading, we have the technical expertise and practical skills to evaluate gemstones by the 4C’s (color, clarity, cut and carat weight), the International Diamond Grading System and the Colored Stone Grading System.

Graduate Gemologists are also experts in identifying and valuing common and unusual gemstones, as well as pearls. We understand the short-comings of emeralds, and how to buy them properly. Natural sapphires and rubies are the most valuable, and we can identify heat-treated or lab-created stones. Similar to diamonds, the value of a colored stone is in the gemological details, and we only purchase the finest gemstones.

If you have questions about diamond grading, or want to know why two near-identical diamonds are priced differently, call Gemological Trading Corporation at (206) 625-0105. We enjoy discussing gemology and helping people buy exceptional diamonds and colored stones.
