Ring in white gold, 750 MM, set with an oval Paraiba tourmaline weighing 13.22 carats sold with its certificate of the CGL Laboratory "Paraiba grey blue" finely hemmed with diamonds totaling 0.70 carat. Exceptional stone. "Paraiba" is the name of a region and deposit in Brazil now virtually exhausted where these first tourmalines were found in 1989. Deposits were discovered in Mozanbique and Nigeria with the same chemical components in 2001 and 2005. Their production is also very limited. Due to their rarity and the interest of the Haute Joaillerie, these rare tourmalines from blue to green, are very sought after, size: 52, weight: 7.9gr. gross. Video on request to the study
