The International Gem Society (IGS) has a list of businesses offering gemstone appraisal services.
Value for amethysts depends almost entirely on color. Siberian mines once produced the world’s finest stones. They featured a particularly rich purple color that glowed with red and blue flashes. Today the term “Siberian” no longer refers to origins. Instead, this is now a trade and grade term referring to colors similar to those of the amethysts mined in Siberia.
Although Siberian reigns atop the value listing, light-colored amethyst has enjoyed a resurgence in popularity. The lightest, pinkish violet shades are called “Rose de France,” a clever bit of marketing. The artistry of gemstone faceting can shine through these gems if given fancy and unusual cuts.
Since amethyst is readily available in large sizes, its value per carat climbs gradually, not exponentially. Since this stone is plentiful, there is little reason to pay top dollar for pieces with visible inclusions or inferior cutting.
