Consider the case of one of the most rare and expensive gemstones, diamond. In the colored gemstone world, there is fortunately no cartel, though many forces try to influence market demand and perceived value. Consider for example the terms "precious" and "semi-precious." As most everyone knows, the precious stones are diamond, ruby, sapphire and emerald. But did you know that the list of precious stones once included amethyst? It would be hard to maintain prices for the other "precious" stones if one of the group sold for only $5 a carat! So amethyst was demoted.

These days some rare semi-precious stones such as alexandrite and demantoid garnet can be more expensive than ruby and sapphire. According to the International Colored Gemstone Association (ICGA), the "traditional gemstones" -- ruby, emerald and blue sapphire -- command a premium price in the market due to "their lasting appeal and distinguished history." Less well-known stones which are not heavily marketed often have very reasonable prices in the market. Then there is a list of gems the ICGA calls "affordable gemstones" -- nicely colored stones which have good availability and attractive prices. These include amethyst, citrine, ametrine, peridot, rhodolite garnet, blue topaz, iolite, kunzite, diopside and andalusite.

If a gemstone has a very good supply, as in the last category, there is not much the jewelry industry can do to influence prices unless they can control the supply like the De Beers cartel did with diamonds. The brilliance of zircon is hard to equal unless you buy diamond.
