Tourmaline is extremely popular among collectors and is a well-known gemstone. It is the most multicoloured mineral type known, occurring in virtually every colour of the spectrum. Individual stones are often multicoloured and are unsurpassed in their beauty. The colour of some Tourmaline can be enhanced through Heat treatment. Some greenish stones can be made deep green, some brownish-red stones can be made red, and some light pink stones can be made colourless through heating. Tourmaline has many interesting optical properties. Many green and blue specimens are strongly pleochroic. Indicolite is one of the most valuable and collectable of all elbaite Tourmaline’s, with hues spanning from lighter to deep, intense blues. Cutting indicolite can be a task for even the most skilled of cutters, as it is strongly Pleochroic and appears darker when viewed down the crystal. This factor must be taken into consideration when cutting, as a loss of transparency and brilliance can occur in darker specimens.
