Monte Belo indicolite is coveted for its beauty and rarity, gaining the highest value for collectors when it shows an intense, clear, radiant blue reminiscent of premium sapphire. This is a gem that displays pleochroism, meaning that it appears different colors when viewed from different angles.
Gemstone specialists refer to indicolite as "indigolith," meaning blue stone. Indicolite gemstones larger than one or two carats are quite valuable, and those larger than four or five carats are extremely rare and expensive. These beauties are considered among the rarest of gemstones and also the rarest variety of tourmaline, next to Paraiba.
Tourmaline, when heated or rubbed, creates an electrical charge becoming a magnet that attracts lightweight materials. Almost all tourmaline has been heat treated for color enhancement, including indicolite.
Tourmaline is one of the most colorful gemstone groups, with varieties in green, red, blue, yellow, black, and colorless. Some even display two or more colors at once.
