Below is a sample of our Gem Price Guide. To see the full guide, please become a Gold Member.

Understand that this is just a guide. The prices are based on a variety of sources for commonly traded goods, however gems are sold outside this range every day.

Prices listed are retail. Wholesale is usually one third to one half of retail. Very low priced goods are often marked up quite considerably more and high end gems 30% or less.

The price a gem will sell for is based on several factors. One is the dealer. Just because Tiffany’s can get $7,000 for a particular gem, does not mean you can.

Quality is one of the most important factors in valuing a gem. Subtle variations in quality can make a substantial difference in the price of high end goods. Unless you are familiar with all the subtle nuances of color, cut, and clarity, per size availability, you will not be able to accurately judge the value of a gem. Few people have the experience to do this accurately and that includes most jewelers.

There are no laws or regulations regarding gem appraisals. Many people write appraisals that do not have the experience to arrive at an accurate value. Still others take advantage in the lack of regulation and purposely write appraisals at highly inflated values. So, do not give much merit to an appraisal unless it is from a highly respected company.

Realize that buyers and seller often disagree on the quality. In the final analysis, a gem is simply worth what a buyer and seller can agree upon.
