A superb, 3-dimensional, vuggy cluster of very gemmy, sharp, lustrous, sea-green boracite crystals from the Boulby Mine of England. Boracite is a rare borate and this is a very rich and fine, older specimen for the species and classic locality. This specimen is solid boracite. Ex. Lindsay Greenbank and Robert Whitmore Collections. Lindsay is a noted English collector. These came out in the early 1990s (see upcoming issue of the Mineralogical Record on the Greenbank Collection for more info) .
