Unheated Paraiba Tourmaline Eireita Brazil Ring with Certificate of Authenticity

This is a rare, non-heated Paraiba tourmaline ring. It is a genuine Heitorita from Brazil, proven to be non-heated by its appraisal certificate. As indicated by its high copper content of 3.54%, it possesses a deep blue color. Paraiba tourmalines with over 3% copper content, especially when non-heated, are almost non-existent on the market. Furthermore, the round brilliant cut is said to be very rare. Depending on the light, a bright neon blue sparkles from within the deep blue, making it a truly beautiful stone. Although difficult to capture in photos, there are small cracks on the surface of the loose stone. They are barely visible to the eye, but please check them in the 20th image. (Photographed at an angle and with lighting specifically to make them noticeable.) Please only purchase if you understand that cracks and inclusions are natural characteristics of gemstones. The simple design should allow for resizing. (We do not offer resizing services.) This is a precious item that you may never encounter again, so we are not considering significant price reductions.
