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.

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.

A type of clear quartz, tourmalinated Quartz tumbled is valued for its dark, needle-like inclusions that give interest to a grayish background stone. It is mined in many localities around the world, but the most important mines are located in Brazil. It is often cut into beads and used in jewelry-making.

Resembling the coat of the Dalmatian dog breed, the dalmatian Stone tumbled is mined out of the material found in Chihuahua, Mexico. This semi-precious stone takes polish very well and it's often seen in the form of tumbled stones, cabochons, beads, spheres, and other carved objects. It also accepts dye readily, so it's often sold in various different colors.
