Sulfur on Calcite (drill core) (RARE important locality specimen)

Item Description

An incredibly hard to find specimen from the Boling Salt Dome locality southwest of Houston (specifically NNE of the town of Newgulf). I encourage everybody to read the statistics about the locality on mindat.org ( https://www.mindat.org/loc-309... ), my favorite being the sheer size of dome itself, which was calculated at 31.3 cubic miles. We've only seen a handful of these specimens over the years, and this one is by far the biggest and heftiest (it weighs 4,492 grams - nearly 10 pounds!). The piece is a section of a rotary drill core used to essentially gauge the magnitude or volume of a commodity in a certain section of the deposit. The piece features an open exposed vug lined with sparkling cream colored Calcite crystals and hosts a sharp, well-formed, bright lemon yellow Sulfur crystal measuring 1.7 cm. The crystal itself is undamaged and shows good inner gemminess when backlit. Smaller partial crystals of Sulfur can be seen on the piece as well, but the it's main vug that counts here. Minerals from Texas are not terribly common to find on the market, but this piece is different than most you'll see due to the interesting nature of its extraction and the shape of the piece from the drill core. It's important to note that actual crystallized sulfur from this locality is EXTREMELY hard to find because the mining company actually dissolved the Sulfur with superheated water and compressed air and collected it from deep wells underground, so nearly all the crystals were "melted" away. A must have specimen for any fan of worldwide Sulfur specimens or minerals of Texas. PLEASE NOTE: Due to the weight of the specimen, an additional shipping charge will be required.
