Physical properties

Hardness: 6.5-7 Mohs; Color: translucscent orange-red (Carnelian) and pink with speckles (Strawberry Quartz); Luster: Vitreous to waxy; Structure: Hexagonal (trigonal); Specific Gravity: 2.6-2.7

Formation & geological history

Forms in hydrothermal veins and cavities. Carnelian forms as silica-rich water percolates through volcanic rock; Strawberry Quartz gains its color from hematite or goethite needle inclusions.

Uses & applications

Ornamental jewelry, beadwork, and decorative arts. Highly valued in metaphysical and collector circles.

Geological facts

Carnelian has been used for signet rings since Ancient Egypt and Rome. Strawberry quartz is often confused with Rose Quartz but is distinguished by its distinct mineral inclusions.

Field identification & locations

Identify by translucency, lack of bubbles (distinguishing from glass), and the presence of natural iron-oxide inclusions. Common sources include Brazil, India, and Madagascar.
