Here we have a stunning matrix piece from the well known Gröna Mine near Bernburg at Stassfurt. Lustrous and gemmy, these dark, gray-green Boracite crystals, measuring up to 0.5 cm, scattered over this beautiful specimen. Actually attractive in their own way, it is not a "rare ugly." The Boracites have sharply beveled edges and modified corners, and are interpenetrating. This is a classic, textbook example of this rare species with crystals of large size, combining to make a competitive-level miniature specimen. This highly attractive piece is valued in our stock with € 1500 and so much better in kind.
