Crushed Stichtite and Green Serpentine (Atlanisite) Sand from South Africa, Medium Sand (0.25mm-2mm)

Atlantisite is a rare metamorphic rock that consists of a purple mineral, named stichtite, that is intergrown with green serpentine. These metamorphic minerals form near areas where hydrothermal alteration has happened in the Earth's crust. This occurs when heated fluids penetrate the host rock and chemically modify other “host” minerals to produce serpentine and stichtite. This particular crushed Atlantisite is of exceptional quality (Grade A), with an even blend of vivid purple and mossy green hues. This unique mix is definitely reminiscent of a serpent or dragon. Our medium material is considered to be sand sized (very coarse sand to fine sand), ranging between 2 millimeters to 0.25 millimeters. Please see the corresponding sediment size chart.  Mineral Properties Mohs’s Hardness: 1.5 - 2 (Stichtite), 2.5 - 5.5 (Serpentine) Specific Gravity (g/cm3): 2.44 - 2.80 Luster: Opaque, Dull Color: Purple, Green Origin: South Africa This product is not man-made, mixed with resin, dyed, o
