Information about Black Obsidian
One of the most common colours of Obsidian, this gorgeous black glass was formed by rhyolitic volcanic eruptions thousands, if not millions of years ago.
Some pieces can be blacker than others – a dark brown colour is reasonably common too.
Some pieces of this Obsidian can have play of colour, sometimes known as ‘Rainbow Obsidian’, or a glorious sheen, which occurs in several colours including silver and golden.
