In the early 90’s I wrote an article for the Columbia Business Journal about the commoditization of diamond trading and the shift away from romanticizing the diamond purchase. Since that time, the jewelry industry has changed greatly. Romance is still important, but today’s consumer has more options, and there are no exact numbers that might enable a diamond purchase based solely on the gradings given by any particular certifying organization. Diamonds are priced based on the gemstone as well as by the grading. Furthermore, diamond grading is subjective and there are good (diamond cutter friendly) grades and poor grades. Some VS2 clarity gradings are closer to VS1, and some are closer to SI1. In addition, a diamond can have an excellent cut grade but be poorly proportioned. If all of the facets are symmetrical, it could get an excellent cut grade even though the pavilion angle (which determines light return and brilliance) could be way off.
Analyzing cut proportions and understanding the slight nuances that can drastically affect diamond pricing and value is why you should consult a diamond expert when buying your diamond. The diamond cutter we use offers a lower cost than other on-line buying services that are open to the public, and our fee is an average of 10% above the list price for helping you select the finest and most brilliant diamond you can get for your money. You can purchase your diamond at wholesale cost and get it worry free from a jeweler at the same time!
