Sulfur & Calcite (rare texas mineral!)

Item Description

A 1.3 cm, sharp, lustrous and translucent, rich canary-yellow sulfur crystal dominates the drusy calcite matrix on this adorable thumbnail combination from Texas. VERY RARE, as this piece is from a drill core from an oil well. Geologists during the 1950s to 1980s used to keep these rare drill core pockets of sulfur when found, and give them as gifts around the area here in Texas. In practice, they are almost impossible to find on the market for this reason. After all, nobody really could have afforded to collect them as specimens per se, not when spending tens of thousands of dollars per drill, if not more! And then, many didn't go to collectors, but to oil companies for unique office decor or as gifts. In a way, that makes these among the worlds most expensively mined mineral specimens, I suppose.
