Named for its discovery in Paraiba Brazil, this variety of tourmaline has since been found in other parts of the world. As with many gems, Paraiba Tourmaline looks different with varying light sources and backgrounds. This stone weighs a modest .45 carat and throws more than its fair share of color for the eye to enjoy. Professional Gem Sciences Laboratory in Chicago Il. confirmed this tourmaline as Natural Paraiba type, via chemical analysis in their report # 43080151 and describe the color as Intense Greenish Blue. Diamond accents are of scale for this piece and securely set bezel fashion in this 14 karat white gold ring. We size and ship this item at no additional charge.
