180 (+ 3-5) stones "Frost Obsidian", 21.5 x 10 mm
Obsidian is a volcanic rock formed by the rapid cooling of lava. It is a glassy, black substance characterised by a lack of crystal structure. Black obsidian is a special variant of this volcanic glass and is characterised by its deep black colour. The black colour of obsidian is due to the presence of iron and magnesium and the rapid cooling of the lava, which leaves no time for crystals to form. Historically, black obsidian has been used by various cultures as a cutting tool, weapon and ritual tool. Due to its sharp edges, it was often used for tools and weapons in the Stone Age. Due to its deep black colour, black obsidian is often used in jewellery, pendants and as a decorative material. Its smooth surface and sharp edges make it a popular material for handmade jewellery.
