This is a 1.14ct neon blue paraiba (copper bearing) tourmaline. This stone was sold to me as Brazilian, however, I have no documentation to absolutely prove the Country of origin. This stone was purchased about 14 years ago from a Jeweler who retired. This stone measures approximately 9.5 x 5.3mm. This stone is pretty clean for a paraiba tourmaline and it has that pool water blue color everyone is looking for. These blue paraiba tourmaline are from my personal collection. I did not intend on selling them for a long time because prices continue to increase every year, however, I have some bills that need paid off. My loss is your gain. I'm asking $2850.
