Source special issue: classic-minerals-of-northern-england, PDF page: 57. Label: (Above) Boracite crystal cluster, 7 cm, showing sharp, tetragonal crystals to 5 mm, from the Boulby potash mine, Cleveland, North Yorkshire (LG-491). The hard, tough nodules of boracite in the Boulby deposit cause damage to mining machinery designed to process the compact but easily worked sylvite and halite. Miners and collectors were slow to realize the unique worth of these stony masses, but word eventually spread and the deposit is now recognized as the source of some of the finest specimens of boracite ever found. The specimen shown here was mined in 1993. Joe Budd photo.
