Paraiba tourmaline is famed for its electric, copper-bearing neon blue-green glow. An October birthstone, it rates 7 to 7.5 on the Mohs scale and holds up to everyday wear. Its lively colour makes it a rewarding choice for a one of a kind design. Loose and unmounted, it can anchor a ring, hang as a pendant, or accent your own design.
