18.26 ct. Paraiba Tourmaline, GIA, AGL, SSEF, Unset Pendant Collector Gemstone

SKU 18.26 Paraiba Tourmaline

This exceptionally fine quality paraiba tourmaline is truly spectacular! It is large, clean and highly crystalline. It weighs 18.26 carats and possesses an intense, distinctive “Windex" blue color. Superior clarity gives this gem extraordinary brilliance, and it is accompanied by not one, but three laboratory reports. While the Gemological Institute of America confirms that this stone is definitely the copper and manganese-bearing paraiba variety of tourmaline, the Swiss Gemmological Institute states that this paraiba is from Mozambique, and the American Gemological Laboratories has determined that it is from Brazil. In light of the inconclusiveness of its origin, this stone is priced as a Mozambique paraiba and does not reflect the premium placed on paraibas from Brazil. Regardless of where it originated, this is a world-class gem. A beautifully proportioned cushion with excellent luster and vivid, intense color, this magnificent Paraiba tourmaline is one-in-a-million!
