Large black obsidian sphere - 25 cm - 18 kg

AMAZING black obsidian ball, outstanding 25 cm diameter, weight more than 18 kg! The ball is just perfect without inclusions of other minerals and fracture typical of the black obsidian, being volcanic glass. Impossible to repeat and find. For connoisseurs and collectors of minerals. The ball is sold like used, because it's part of my private collection, but I guarantee that is just perfect. Extracted from a block of more than 60 kg, expertly crafted with care by the best craftsmen in 1980s and come to the present day thanks to a passion for unique objects for collectors. Only with experience gained over time in the selection of unique minerals and perfect to work, over the years I have been able to collect unique pieces now once-off for the lower quality of raw material and extremely high costs. For the fragility and uniqueness of the object I prefer hand delivery, to be agreed. Unique pieces from my private family collection built during more than 60 years of working with semi-precious stones.
