Wholesale Sphalerite from Spain ~ Random Pick ~ Spanish Zinc Sulfide

This listing is for two random-pick options of Sphalerite from Spain. Sphalerite is a stone of protection, known for helping distinguish reality from delusion, providing both emotional healing and grounding. Sphalerite primarily comes from the Aliva Mine in the Picos de Europa, Cantabria, and the Troya Mine in Mutiloa, Gipuzkoa, Basque Country. Scientifically, Sphalerite is a zinc sulfide (ZnS) mineral that is colorless in pure form but can appear yellow, orange, red, brown, green, or black depending on trace elements like iron, cobalt, and others. Spanish sphalerite is especially admired for its high refractive index (2.37) and exceptional dispersion (>0.150), which gives it remarkable brilliance when faceted. However, it is soft (Mohs hardness 3.5–4) and brittle, with perfect cleavage, making it challenging to cut and unsuitable for most jewelry.
