Obsidian is a natural glass that forms when lava cools and hardens rapidly, minimizing the formation of crystal structures. As a result, obsidian, also known as Volcanic Glass, is smooth and has a very high luster. It has been used since prehistoric times with numerous applications, to make basic tools, mirrors and jewelry. Obsidian is often cut en cabochon to maximize its glassy luster, but it may also be faceted to give it more depth and character. Although it seems a tough stone, obsidian ranks at 5.5 on the Mohs scale and is fairly soft. It is easily scratched and is prone to breakage if exposed to rough wear or blows. However, with appropriate care, obsidian jewelry can last a long time. Obsidian is a very stylish gemstone and is used to create glamorous pieces. Whether in delicate, small pieces or large statement items, obsidian suits all sorts of jewelry.
