Ruby in Kyanite tumbled

The popularity of blue Quartzite tumbled comes from its delicate color, which can range from a bright middle blue to a bluish-gray. Some stones are solid in color, while others have irregular distributions of intense blue markings and bands. Besides the tumbled stones available on the market, the material is also cut into beads and cabochons. This stone is mined in India, France, USA, Austria, Russia, and Madagascar

Antigorite is a lamellated, monoclinic mineral in the phylosilicate serpentine subgroup with the ideal chemical formula of (Mg,Fe)3Si2O5(OH)4. It is the high-pressure polymorph of serpentine and is commonly found in metamorphosed serpentinites. Antigorite, and its serpentine polymorphs, play an important role in subduction zone dynamics due to their relative weakness and high weight percent of water (up to 13 weight % H2O). It is named after its type locality, the Geisspfad serpentinite, Valle Antigorio in the border region of Italy/Switzerland and is commonly used as a gemstone in jewelry and carvings.

Fake Sapphire refers to a synthetic or natural material created to mimic the appearance of a natural sapphire. An example of fake Sapphire includes glass, synthetic spinel, cubic zirconia, and synthetic corundum. This material is typically more affordable than a natural sapphire, making it appealing for budget-conscious consumers seeking a similar aesthetic. However, fake Sapphire lacks the value and durability of a genuine sapphire, resulting in a lower long-term value.

Pyrophyllite is a phyllosilicate mineral composed of aluminium silicate hydroxide: Al2Si4O10(OH)2. It occurs in two forms (habits): crystalline folia and compact masses; distinct crystals are not known. The folia have a pronounced pearly luster, owing to the presence of a perfect cleavage parallel to their surfaces: they are flexible but not elastic, and are usually arranged radially in fan-like or spherical groups. This variety, when heated , exfoliates and swells up to many times its original volume, hence the name pyrophyllite, from the Greek pyro- (πυρο-, the combining form of πῦρ fire) and phyllos (a leaf), given by R. Hermann in 1829. The color of both varieties is white, pale green, greyish or yellowish; they are very soft (hardness of 1.0 to 1.5) and are greasy to the touch. The specific gravity is 2.65 - 2.85. The two varieties are thus very similar to talc.
