LAPIS LAZULI (The main component of lapis lazuli is lazurite (25% to 40%), a feldspathoid silicate mineral. Most  also contains calcite (white), sodalite (blue), and pyrite (metallic yellow). Some lapis lazuli contains trace amounts of the sulfur-rich löllingite variety geyerite.  Lapis lazuli usually occurs in crystalline marble as a result of contact metamorphism.)- Afghanistan

Epidote & Unakite: Green Epidote Gemstone Info

Epidote is a silicate mineral, a calcium aluminum iron silicate. It has a hardness of 6 to 7 on the Mohs scale. One of its distinguishing characteristics is strong pleochroism, where crystals display different colors -- green, brown and yellow -- as they

Benitoite is a rare blue barium titanium silicate mineral, found in hydrothermally altered serpentinite. It fluoresces under short wave ultraviolet light, appearing bright blue to bluish white in color.  First described in 1907 by George D. Louderback, who named it benitoite for its occurrence in San Benito County, California.  It is California's official state gem.  Benitiote has a rare 5 pointed crystal form, and an even rarer 6 pointed form, "star of David", with about 24 samples known.

Astrophyllite, from the mineralogical museum in Kirovsk in Russia. A very rare mineral, and rather soft so particularly fragile.  Astrophyllite is a very rare, brown to golden-yellow hydrous potassium iron titanium silicate mineral. Belonging to the astrophyllite group, astrophyllite may be classed either as an inosilicate, phyllosilicate, or an intermediate between the two.

Musgravite 35K a carat. Musgravite is one of the newest and most rare gemstones in the world. Musgravite is a silicate mineral whose main ingredients are beryllium (Be), magnesium (Mg) and aluminum (Al). It was named ‘musgravite’ after the area Musgrave in Australia from where the material was first found. The musgravite was later found also in Greenland and Madagascar, but neither of them produces gem quality material.

"The abundant concretions found in the Navajo Sandstone consist of sandstone cemented together by hematite (Fe2O3), and goethite (FeOOH). The iron forming these concretions came from the breakdown of iron-bearing silicate minerals by weathering to form iron oxide coatings on other grains." en.wikipedia.org/wiki/Navajo_Sandstone#Iron_oxide_concret...
