Natural rough white-blue topaz .

Topaz is an aluminosilicate that is usually found in pegmatites, rhyolite cavities and in hydrothermal veins. It forms well-developed crystals and is often used as a gem for jewelry making.

The mineral includes a label with the name and origin and is attached to a cardboard box. 4 cm square.

*The price is per unit (a single cardboard box of the four shown in the photo)

    Since the minerals are natural, you will receive a piece similar to the one in the photograph. The minerals come in cardboard boxes and are glued to a porex base with hot silicone; these can be removed using ethyl alcohol without damaging the mineral. The size is approximate.
