Product Details

As we read in the book Gemstones: Terra Connoisseur, “Introduced to the trade at the Tucson Gem Show in 1990, initial skepticism about this spectacular stone was replaced by awe when the sales jumped from $250 a carat to $2500”. Last decade the price was $18000/ct, and in May 2018 Christie’s fetched a dazzling record of $180000/ct. Are you waiting for the escalation of price and exhaustion of mining, or are you ready to buy Paraiba Tourmaline now?
