Product description: Chrome tourmaline is a rather special member of the tourmaline group. Found only in east Africa, it is usually found mainly in small sizes. But what it lacks in size it makes up for in color - it displays perhaps the richest, most intense green in the gemstone world. Chrome tourmaline is distinguished from the more common and less vibrant green tourmaline by its chromium content. Collectors can test for chromium content with a Chelsea filter. Under the filter, stones that contain chrome will show flashes of red or orangy red.
