This is a 4.80ct certified and appraise neon pink paraiba (copper bearing) tourmaline. This stone is from Mozambique This stone measures approximately 14.3 x 8.3mm. It was appraised back on 2010. Paraiba tourmaline have increased in value greatly since that time. This stone is pretty clean for a paraiba tourmaline and it has a nice neon pink color that is not very common for a stone of this size. 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, howdever, I have some bills that need paid off. My loss is your gain. I'm asking $2750 USD.
