Gem Price Guide

This is a guide to gem values based largely upon qualitative evaluations of things like, cut clarity, and color. Those evaluations are inherently subjective, and therefore the values derived from those determinations are also subjective. Each market participant perceives the cut, clarity, and color of a given gem differently. Realize that buyers and seller often disagree on the quality, and the price or value of a gem is what one willing buyer and one willing seller can agree upon. These values are just a guide. Color descriptions are listed for many gems. If you need help understanding them, see Evaluating Color – hue, tone, and saturation.

The values in our guide are sourced from a variety of sources including primarily and secondary gemstone dealers, jewelers, miners, and wholesale suppliers of commonly traded goods. You should keep in mind that gems are sold outside these price ranges every day. Prices listed are retail. Wholesale is usually one third of retail. High-end gems are often marked up 30% or less, while low-priced more “commercial quality” gems are often marked up considerably more.

The price your gem will sell for is based upon several factors. 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 you will not be able to accurately judge the value of a gem even with this guide (you should consider getting an appraisal, which is a service IGS provides). 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 capitalize on the lack of regulation and purposely write appraisals at highly inflated values. Do not give much merit to an appraisal unless it is from a highly respected organization or a reputable gem dealer who knows market prices and deals in the material they are valuing.

    Composite Opals

    Doublets prices are usually 15% to 35% of the value of similar looking natural, (solid,) gem. However, they occasionally run as high as 50% of a natural opal if they are of exceptional quality.

    Triplets are only about 1% of the value of an equivalent natural and peak at $⊝⊝⊝.
