Quartz is one of the most common minerals in the Earth's continental crust. The most important
distinction between types of quartz is that of macrocrystalline (individual crystals visible to
the unaided eye) and the microcrystalline or cryptocrystalline varieties (aggregates of crystals
visible only under high magnification). Major varieties:

Agate:  banded chalcedony, translucent
Amethyst:  purple, transparent
Aventurine:  translucent chalcedony with small inclusions (usually mica) that shimmer
Carnelian:  reddish orange chalcedony, translucent
Chalcedony:  any cryptocrystalline quartz, although generally only used for white or lightly colored material
Citrine:  yellow to reddish orange, greenish yellow
Jasper:  opaque chalcedony, impure
Milk Quartz (Snow Quartz):  white, translucent to opaque
Morion:  dark-brown, opaque
Onyx:  agate where the bands are straight, parallel and consistent in size
Prasiolite:  mint green, transparent
Rock Crystal:  clear, colorless
Rose Quartz (Pink Quartz):  pink, translucent
Smoky Quartz:  gray or brown, transparent
Tigereye:  fibrous quartz, exhibiting chatoyancy
