Nowadays, the intensely colored Paraiba tourmalines are true treasures, not only as impressive gemstones, but also as wearable investments. No other colored gemstone has experienced such a steep rise as the Paraiba tourmaline in the past thirty years. Thus, these stones are also traded as investment stones. Overall, the prices for this gemstone are rising steadily. Paraiba tourmalines from the Brazilian state of Paraiba are the most sought after and expensive. However, the deposits from Brazil have long been exhausted. In 2001, blue-green tourmalines containing copper and manganese were discovered in Nigeria, and in 2005, Mozambique was added to the list. In the meantime, almost all Paraiba Tourmalines available on the market come from Africa, not from Brazil. However, African deposits are also proving to be very limited, which will lead to further price increases. Prices currently range from $2,000 (moderate quality) to $30,000 (best quality) per carat! ATTENTION: We are dealing with new goods. The hammer price includes 19% sales tax, which will be shown!
