About some of the Gemstones Jasper is a variety of chalcedony, which is a cryptocrystalline form of silica. Its chemical formula is SiO2 and it has a hexagonal crystal system. Jasper, an aggregate of microgranular quartz and/or cryptocrystalline chalcedony and other mineral phases, is an opaque, impure variety of silica. The common red color is due to iron(III) inclusions. Lapis lazuli, or lapis for short, is a deep-blue metamorphic rock used as a semi-precious stone that has been prized since antiquity for its intense color. The most important mineral component of lapis is lazurite (25% to 40%), a blue feldspathoid silicate mineral. Most lapis also contains calcite (white), sodalite (blue), and pyrite (metallic yellow). Amethyst is a purple semiprecious variety of quartz and owes its violet color to irradiation, impurities of iron and in some cases other transition metals, and the presence of other trace elements. All of which result in complex crystal lattice substitutions. Often used in jewelry it is the traditional birthstone for February. The name comes from the Greek αμέθυστος amethystos, "intoxicate", a reference to the belief that the stone protected its owner from drunkenness. Ancient Greeks wore amethyst and carved drinking vessels from it in the belief that it would prevent intoxication. Red Agate, also known as the Warrior's Stone, has an orange to reddish hue. It was used by the Ancients on the breastplates of armor to give warriors strength and make them victorious in battle. Aventurine is another form of quartz, characterized by its translucency and the presence of platy mineral inclusions that give it a shimmering or glistening effect termed aventurescence. Rose quartz (also known as Hyaline quartz) is a translucent, usually turbid, very coarse-grained variety of the silica mineral quartz found in pegmatites. Rose quartz is valued for its rich pink color. It has been carved since early times and has been faceted to provide gems of good brilliance. Obsidian is a naturally occurring volcanic glass formed when lava extruded from a volcano cools rapidly with minimal crystal growth. Obsidian is hard, brittle, and amorphous and thus fractures with razor sharp edges. It played a key role for our ancestors survival as cutting and piercing tools.
