Gemstone Treatments

Enhancements have been used for centuries, involving everything from coarsely dabbing the gemstone with dye to today’s more sophisticated methods like irradiation. Anyone who believes color-enhancing diamonds is unusual should consider the fact that many other gemstones regularly get treated one way or another to intensify color, diminish imperfections, or improve durability.
For instance, that beautiful deep blue many have come to associate with tanzanites is rarely these stones’ natural color. Though some natural blue tanzanites exist, the vast majority are brown or orange-brown when mined. Gentle heating gives these crystals more marketable colors.
