It is the most expensive and rare of garnet gemstones, with fine specimens commanding prices of thousands of dollars per carat! It has many similarities with the diamond ("demant"), hence its name (meaning 'diamond-like'), but it has low hardness, so that it is not suitable forhard wear as jewelry. The stones have inclusions of fine asbestos fibers (byssolite) that are sometimes called ponytails.
