Quartz Cabochons
Quartz is one of the most common minerals on earth, and is well known in the gems world in its many forms - amethyst, citrine, ametrine, smoky quartz, rose quartz and lemon quartz. Quartz is attractive and durable, as well as inexpensive. It can be cut and carved in many forms and sizes.

There are 2 main varieties of quartz, including both crystalline and cryptocrystalline quartz. Crystalline quartz occurs in distinct transparent crystals, such as in amethyst and citrine. In cryptocrystalline quartz, the crystals are microscopic and the quartz is opaque or translucent. Examples include chalcedony and agate.

Size and Weight

Gems are always measured in Millimeter (mm)

Dimensions are given as;
length x width x depth,
except for round stones which are;
diameter x depth

Select gems by size, not by weight!
Gem varieties vary in density, so carat weight is not a good indication of size

Note: 1ct = 0.2g
