Barite
Barite is the world's primary source of barium and is most familiar to collectors as "desert roses" — rosette-shaped crystal clusters that form in Oklahoma's red soils. It is the state rock of Oklahoma. Blue barite crystals from Colorado are world-class collecting specimens. Despite being a "heavy" mineral (SG 4.3–4.6), barite is surprisingly soft and can be confused with calcite without testing.

🔍 Field Identification Tips
Very heavy for a non-metallic mineral (SG 4.3 — feels much heavier than expected). Perfect cleavage in two directions. Hardness 3–3.5 (steel knife scratches easily). Does NOT fizz in acid (distinguishes from calcite). Oklahoma desert roses have a distinctive sandy, granular texture from incorporated sand grains.
