Gemmy, light greenish blue Boracite crystals measuring to 3 mm form a rich druse over the top faces of creamy yellow Magnesite with associated scattered crystals of orange red Hilgardite. From Boulby mine (aka Boulby Potash mine) at Loftus, near to Staithes in North Yorkshire, England. Boulby’s surface plant is adjacent to the North Sea coast, with its deep underground workings extending far out beneath the sea. The mine still operates and is currently the second deepest mine in Europe at about 1,400 m (4,600 ft). The Boracite forms pseudo-cubic crystals and this miniature specimen is from Panel 282 within the mine. It is accompanied with a Lindsay Greenbank label, No. LG.577.
