This is one of the largest celestite crystals that I have ever seen, although it must have been even larger at one time - one end has been cleaved off, leaving a crystal fragment that is merely 7" x 2.1" x 0.6". This huge crystal is blue and transparent in areas, although its clarity is obscured through most of the crystal by a milky white inclusion, which takes the form of a large arrow. The crystal is also criss-crossed by a network of cleavage planes, which add a colorful sparkle when the light hits them right. The back of the specimen is covered with thousands of small crystals which look like more celestite to me. There is also a bit of host rock attached, which itself contains many more small celestite crystals. In addition to the cleaved end, there is some minor damage to some of the edges on the good termination. Even with the damage and milky inclusions, this is an impressive crystal of celestite.
