Physical properties
Hardness: 7 (Mohs scale); Color: Clear with reddish-pink specks; Luster: Vitreous; Crystal Structure: Hexagonal; Cleavage: None; Specific Gravity: 2.65
Formation & geological history
Forms in igneous pegmatites or hydrothermal veins where quartz crystallizes alongside iron-rich minerals like hematite or goethite, which become trapped as inclusions.
Uses & applications
Primarily used as a gemstone in jewelry, for decorative carvings, and highly valued by mineral collectors for its unique aesthetics.
Geological facts
True 'Strawberry Quartz' is relatively rare; many specimens on the market are actually synthetic glass or Tanzanian 'Cherry Quartz'. Genuine specimens contain lepidocrocite or hematite needles.
Field identification & locations
Identify by hexagonal crystal habit and internal reddish flecks that do not rub off. The location 11.6°N, 43.1°E (Djibouti/East Africa) is near volcanic rift zones where quartz and hydrothermal minerals are common.
