GEMSTONE LAB

Quartz has the most semiprecious gemstones of all minerals. Pure quartz is clear, so any impurity will allow the gem to have that color. Amethyst, is prized for it’s deep purple color. The color caused by traces of ferric iron, determines the price of amethyst, the more intense and pure the color is the higher the price. However, some pale lilac, which was once considered low grade, has been recently marketed as "Rose de France." With its unusual cuts, it is gaining popularity and hence value.
