A beautiful glassy spray of powder blue crystals radiating upward from a massive base. This is a very old specimen from the classic Sulfur locality that has been mined for many centuries. This type of Celestite with the blue color has sometimes been labeled as Barite but often on analysis is found to be Celestite with some Barium. The piece is attractive despite chips and damage to a few crystals. Very uncommon to find material this attractive on the market, the blue color is especially desirable.
