Indicolite Tourmaline Gemstone Guide

Indicolite Tourmaline, also known simply as Blue Tourmaline, is among the rarest, most prized varieties of the elbaite mineral family. Celebrated for its captivating spectrum ranging from deep oceanic navy to vibrant teal and neon turquoise, Indicolite derives its iconic colouration from trace amounts of iron embedded within its complex crystal structure. At Tivon, we select only the top 5% of loose gemstone from this elite elbaite family to guarantee an intense concentration of vivid turquoise blues and electric greens. What makes fine Indicolite particularly mesmerizing to gem collectors is its strong pleochroism, an optical phenomenon where the gemstone displays two distinct shades of blue or blue-green when viewed from different angles. Because intense, clean blue crystals represent less than 1% of all mined tourmalines, fine-grade Indicolite is a true treasure of high jewellery.
