Look at this large Rubellite Tourmaline, the color on this gem along with the neon glow makes this one breath-taking gemstone. This Rubellite measures:9.16 x 11.49mm cut in the oval shape, weight: 4.65 carats, Tourmaline is a 7 to 7 1/2 on the hardness scale, double refractive with a 1.66 on the refractive index, origin: Mozambique, Africa. This gem has been heat treated to bring out the best of its color. This area of Mozambique which this stone was mined has produced some of the best of the cooper bearing Parabia Tourmaline coming out of Africa. We didn't test these Rubellites to see if they were cooper and manganese bearing, so I can't say they are but several of my gemologist freind and myself believe they are some of the cooper bearing gems from this area, because of the color and the neon glow it gives. This piece would make a gorgeous pendent with some diamonds around it. We have 100's & 100's of different types of gemstones so call me for your gem needs. All my pieces have a seven (7) day inspection period. We can have this gem put in a ring casting with a matching set of earrings.
