A classic locality for Boracite crystals, in green and grayish-green equidimensional crystals, is the potash deposits of Bernburg and Stassfurt in Saxony-Anhalt, Germany. Single floater crystals, in
dodecahedral or modified
cubic form, have come from from Lüneburger, Niedersachsen (Lower Saxony), Germany. Transparent green Boracite crystals, mostly in
tetrahedral form, have come from the Glückauf Mine, Sondershausen, Thuringia, Germany.
A more recent find of Boracite is at the Boulby Mine, Loftus, North Yorkshire, England. This locality has produced sea-green crystals, in large clusters many times larger than all previous finds of this mineral. Another recent and important producer of Boracite is Alto Chapare, Cochabamba Department, Bolivia. Crystals from this mine are in cubic form with poor transparency, and usually in matrix. The color ranges from grayish-green to a less common peachy pink.
