Judging quality
Feel the weight first; that heft is diagnostic. Look for translucent, undamaged blades and good crystal terminations. Colorado's blue barite is a benchmark.
Sulfate
Barite
Unusually heavy for a pale mineral — its high barium content makes barite feel like metal in the hand. Grows in blades, roses and elegant tabular crystals.
Care
Soft and cleavable. Handle gently; dust dry.
