Physical properties

Hardness: 3-7 (Calcite vs Quartz), Color: Creamy white with orange/peach iron streaks, Luster: Vitreous to waxy, Crystal Structure: Trigonal/Hexagonal, Cleavage: None (Quartz) to Perfect (Calcite)

Formation & geological history

Formed through hydrothermal processes, sedimentary precipitation, or metamorphism of sandstone/limestone. Peach and orange tones are often due to Hematite or Limonite staining in fractures.

Uses & applications

Commonly used as pocket stones, decorative ornaments, landscape gravel, and in metaphysical practices as a 'healing crystal' for energy and focus.

Geological facts

This specimen appears to be tumbled and polished. Iron oxide is the most common natural 'paint' in geology, responsible for the red, orange, and yellow hues found in rocks worldwide.

Field identification & locations

Identify by checking hardness; quartz will scratch glass, whereas calcite will bubble if exposed to weak acid (like vinegar). Commonly found in riverbeds or near mountain outcrops.
