The International Gem Society (IGS) has a list of businesses offering gemstone appraisal services.

In terms of value, color evenness and saturation are the primary considerations. A turquoise’s capacity for taking a good polish without stabilization is also an important factor. (See “Enhancements” below).

Generally, darker shades and less green tint in blue colors add more value to turquoises. Of course, consumers who appreciate matrix patterns would consider their beauty crucial to determining their value. Spiderweb turquoise, veined with black matrix in a pattern that looks like crocheted lace, is quite popular.

The highest grades of turquoise are used for cabochons, carvings, and inlay. Lower grades are used as polished beads or natural, “nugget-style” beads.

Turquoise enjoys an avid collector market, with sibling rivalries among the various enthusiasts who see virtue in different colors, matrix variations, and mine sites. Just as no gem collection would be complete without several representatives of this species, no jewelry collection should be without at least one piece featuring this beloved traditional December birthstone. (Turquoise is also the birthstone for those born on Saturday).

Turquoise is a real gem bargain. Even the very highest grades of material are modestly priced compared to many other gems. For more information on turquoise value factors, consult our buying guide.
