Blue tourmaline (also known as Indicolite) oval weighing 3.13cts from the Malapa mine, Tanzania. The stone is perfectly fashioned and the deep slightly greenish blue color is exceptional.
Tourmaline is a gemstone noted for the large and unsurpassed range of colors in which it occurs, but blue is one of the rarest and most valuable color sought by collectors and connoisseurs throughout the world. Color of Indicolite (tourmaline) can vary from a light to a deep blue, but pure blue is extremely rare. A teal or blue-green color is most common color of Indicolite. Like most tourmaline, it is strongly pleochroic, meaning it shows different hues when viewed from different directions.
