Bull’s eye is a variety of quartz with intergrowths of parallel fibres of the so-called crocidolite asbestos. It is quite rare and only occurring a few areas in the world. The most popular site is Doorn, South Africa.

Bull’s Eye uniqueness: Bull’s eye is a result of tiger’s eye reddening influenced by thermal processes during rock formation. However, as it occurs quite rarely in nature, the stone is usually made by firing the tiger’s eye with 500°C temperature, during which the stone gets its typical red-brown tint.

Special conditions/ treatment: There is no need for special handling with bull’s eye as it is stable against common detergents.

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.

About the product: Small chips of rough stones have size approx. 7 - 15 mm. The minerals are sold in 5 kg bags, but we also offer a 25 kg package (carton box) for an advantageous price.
