Pallasite Meteorite

A type of Quartz and the most common Aventurine variety, green Aventurine is prized for its emerald-green color. This color is caused by the presence of fuchsite Mica inclusions in Quartz that reflect light. A less expensive substitute for Jade, green Aventurine is regularly formed into beads, pearls, and cabochons, and used with jewelry. It is also used for carved objects, vases, bowls, and sculptures.

The name apophyllite refers to a specific group of phyllosilicates, a class of minerals. Originally, the group name referred to a specific mineral, but was redefined in 1978 to stand for a class of minerals of similar chemical makeup that comprise a solid solution series, and includes the members fluorapophyllite-(K), fluorapophyllite-(Na), hydroxyapophyllite-(K). The name apophyllite is derived from the Greek ἀποφυλλίζω apophylliso, meaning "it flakes off", a reference to this class's tendency to flake apart when heated, due to water loss. Exfoliation of apophyllite is also possible by treating it with acids or simply by rubbing it. These minerals are typically found as secondary minerals in vesicles in basalt or other volcanic rocks. A recent change (2008) in the nomenclature system used for this group was approved by the International Mineralogical Association, removing the prefixes from the species names and using suffixes to designate the species. A subsequent nomenclature change approved by the International Mineralogical Association in 2013 renamed the minerals to include both suffixes and prefixes, as shown above. Though relatively unfamiliar to the general public, apophyllites are fairly prevalent around the world, with specimens coming from some of the world's most well-known mineral localities. These localities include: Jalgaon, India; the Harz Mountains of Germany, Mont Saint-Hilaire in Canada, and Kongsberg, Norway, with other locations in Scotland, Ireland, Brazil, Japan, and throughout the United States.

Tourmaline (/ˈtʊərməlɪn/, -/iːn/ TOOR-mə-lin, -⁠leen) is a crystalline boron silicate mineral compounded with elements such as aluminium, iron, magnesium, sodium, lithium, or potassium. Tourmaline is classified as a semi-precious stone. This gemstone can be found in a wide variety of colors.

Lepidolite tumbled ranges between purple, red, and pink in color, although there is a rare yellow version. Lepidolite tumbled is found in Brazil, Russia, Japan, and the USA. It is used for beads, ornamental items, and cabochons. It is also a popular gemstone when mixed with quartz.

Tumbled petrified Wood tumbled exhibits interesting patterns; some of them resemble trees, branches, or plants. The stones are produced from the material mined in numerous localities around the world, but the largest amounts are found in the United States and Western Australia. It is cut into cabochons, but it's also used for jewelry, crafts, and lapidary work.

Valued for its beauty and durability, tumbled rose Quartz tumbled is a transparent to translucent stone in a beautiful shade of soft pink. This semi-precious stone takes an exceptionally nice polish, so it's most commonly carved and cabbed. Some material is cut into faceted gems. Rose Quartz tumbled is abundant and found in large quantities in many localities around the world.

This variety of quartz, blue in coloring, can range from opaque to translucent. The color comes from inclusions of other minerals. Large pieces of quartzite that contain blue minerals will also sometimes be called blue Quartz. This quartz varietal can be found in Brazil and Spain.
