How to Identify Quartz Crystals
Quartz crystals are six-sided prisms ending in a six-faced point: glassy, hardness 7 (scratches glass and a steel knife), breaking with conchoidal fracture instead of flat cleavage planes. Varieties are color names on the same crystal — smoky, rose, milky, citrine. Calcite mimics the look but scratches with a knife and fizzes in vinegar.
