Amazonite
A turquoise-green variety of the feldspar microcline. Despite the name, it does not come from the Amazon.
Amethyst
Purple quartz whose Greek name means "not drunk". By the common identification, one of the breastplate stones, and one of the best-loved stones in the world.
Aquamarine
The blue-green variety of beryl, a close relative of emerald. Its name means "seawater".
Atlantisite
A natural mix of green serpentine and purple stichtite, from a single hill in Tasmania.
Banded Agate
Chalcedony in colored layers, formed inside rock cavities. How exactly the bands form is still an open question.
Black Tourmaline
Schorl, the most common tourmaline in nature: black, opaque and grooved along its length. Its name comes from a German village that has since changed its own name.
Carnelian
Orange-red chalcedony colored by iron oxides. The Romans loved it for seals, because hot wax doesn't stick to it.
Chrysocolla in Cuprite
Two copper minerals in one stone: blue-green chrysocolla and red cuprite. A desert sunset, only polished.
