Learn about Blue Tourmaline

blue-tourmaline.jpgTourmaline is a gem of many colors, and blue is one of the rarest and thus most valuable. Pure Blue Tourmaline is a darling of collectors: it's a lush, aquamarine or royal shade of blue, and not too dark. Along with Paraiba, most Blue Tourmaline comes from Brazil, although it is sometimes mined in Nigeria, Namibia, Afghanistan and Pakistan. A challenging stone to cut, Blue Tourmaline is quick to crack due to areas of tension inside the stone. An expert lapidary is usually charged with carefully cutting each stone to best illuminate its dichroism (two-coloredness). If you hear a dealer talking about "indilogoth," he is usually referring to Blue Tourmaline.
