The name of this blue tourmaline comes from Sinhala and means "blue stone". Indigolite owes its beautiful color to traces of iron. Blue tourmalines are most valuable when they display an intense, clear, radiant blue and are not too dark. Pure blue indigolites are extremely rare and highly sought after by collectors.
Location also plays a role. Some sites produce much better than average material. The best stones come from Brazil and Namibia. Unfortunately, blue tourmalines that are sometimes more green than blue are sold as indigolites. Indigolite should not be confused with Paraiba tourmaline which can also be blue. Paraiba tourmaline has a much lighter shade that has traces of copper and manganese as a color cause.
When looking at indigolites, the lighting conditions are also important in this context. The color of this tourmaline is best assessed in neutral daylight. Under the light of lamps, the same stone often has a darker shade.
Indigolites are usually transparent and stones over 5 carats of clear color are precious. Larger stones absorb so much light that they become very dark and unattractive. Blue tourmalines come from Brazil, Namibia, Madagascar, Congo and Nigeria.
High quality indigolites are highly sought after collector's stones and are ideal for all types of jewelry. Top quality indigolites are also an excellent investment.
