Obsidian alias volcanic glass is a material with a unique formation, during which hot lava cools rapidly, e.g. in water or on the Earth’s surface. The process is so fast that the individual minerals do not have enough time to crystalize.

Stone´s uniqueness: Obsidian mocca is a charming, brown-black variety of obsidian with mahogany shades. The stone is a result of a merge of two, chemically different, lava varieties. One of these lavas was richer in ore microlites, iron and manganese – which is why mocha obsidian has beautiful black spots.

Use: Our rough stones are a beautiful interior adornment – filling up a vase, fountain or a lamp with them creates an original design. In the exterior, they may be a perfect decoration of gardens. They are also suitable for mineralogist collections and exhibitions. Rough minerals may also be further processed, e.g. small crystals are ideal material for pendants.

Package weight: 1, 2 and 25 kg
