Sulfur and Calcite in drill core (rare) Consie Prince Coll.

Item Description

This is a very rare drill core section, nearly complete all around and showing clearly its origins, that cut into a natural vugs and seams of sulfur and calcite from deep in the ground! Most crystals are broken but some of the rich, yellow, gemmy crystals of sulfur reached 2.0 cm and some are perched on contrasting tiny, sugary white dogtooth calcite crystals. It is beautiful! Geologists during the 1950s to 1980s used to keep these rare 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. I have seen less than a dozen good ones over the years since I moved to Texas the first time, in 1991. The base has been sawed. This is a highly representative example. 1176 grams or 2.6 pounds.
