Description:
A rare, 3.17ct Paraiba tourmaline and diamond necklace. Featuring one copper bearing 3.17 ct, pear shape Paraiba type tourmaline from Mozambique as per Gfgr gem report 026235, and surrounded with small round brilliant cut diamonds, set in two rows all set in 18ct white gold, the pendant is suspended from a double row diamond tennis style necklace. Total diamond weight 17.60 cts. Necklace length 53 cm. Paraiba Tourmalines, are one of the most rare and expensive gemstones in the world, known for their neon blue colour, result of a combination between boron and copper, with a high concentration of copper responsible for the radiant blue and green hues. The stone was discovered in the 1980s in the Paraiba region of Brazil by Heitor Dimas Barbosa and his team. The discovery led to frantic mining activity on Paraiba hill, but five years after the discovery, no tourmaline deposits were found, where this mine is now closed. In 2001, a bright blue tourmaline was also discovered in Nigeria, which took the market by storm. Both stones had to undergo the intense burning process to reveal their true, bright blue self, just like their Brazilian counterparts. Newer lots of the precious stone have been discovered in other areas of Brazil and Mozambique, providing a positive sign for gemstone dealers struggling to meet the immense demand for this rare gem
