Item Description

A notably rare Gypsum specimen from Sulfur Hole, a mineralized columnar pipe locality, that lies below the borax mines. This is the only specimen of this material that we've had to offer. It's a beautiful piece that features attractive "curved" groups of what is called "satin spar" or "ramshorn" style Gypsum with a chatoyant white hue, aesthetically sitting on matrix. The largest group measures 1.3 cm long. Very eye-catching and certainly hard to find on the market.
From the collection of Robert (Bob) Reynolds. Bob was a well-known fossil and mineral expert and former Curator of Earth Sciences at the San Bernardino County Museum in California. The rare phyllomanganate-chromate species Reynoldsite was named in his honor in 2011.
