Black Obsidian Donut Pendant measuring 4 cm
Obsidian
Obsidian is a natural volcanic glass formed during the rapid cooling of silica-rich magma. The mineral usually has a deep black colour and glassy luster, but can also show variants with inclusions or colour splashes, such as snowflake obsidian or rainbow obsidian. Its structure is amorphous, meaning it has no crystal lattice.
Obsidian is found worldwide in volcanic areas, including Iceland, Mexico, the United States and Japan. As it has no crystalline structure, it is not technically classified as a mineral, but as a rock of volcanic origin. Its composition consists mainly of silica (SiOâ‚‚), and its hardness is around 5 to 5.5 on the Mohs scale.

Donuts
Donut gemstone pendants are flat, round pendants with a central drill hole of about 5-6 mm. They are available in various gemstone types and sizes from about 2.5 to 5 cm, with 3 cm being the most common with us. Thanks to their shape, they are easy to wear on a cord or chain.
