Awesome Neon Bluish Green to Steel Paraiba Blue Nigerian Tourmaline Faceting & Cabbing Rough. We estimate that roughly 80% of this stone is Cabbing Grade; however, a nice chunky contiguous section that probably weighs in at about 5-6 or so Grams is almost Eye-clean and we are confident it will produce a spectacular finished stone. We didn't bother to cob this stone as we didn't want to take the chance of it fracturing the wrong way. Ideally you should use a saw to take out the facet rough section in this. The color on this is really quite lovely and we are confident that it should improve considerably moving more towards a Bluer end once it is sawed and/or cobbed out. The price on this just doesn't get any better and we only have 1 piece of this so don't let someone beat you to it!

1. Nigeria has steadily risen to be a powerhouse country for Tourmaline production and is now set to eclipse many traditional sources in sheer volume of material. Overall Nigerian material, like most African material, has the brownish overtones, darker colors and lacks the vibrancy and life that Afghan (and some Namibian and Nigerian) Tourmaline is known for; however, many Nigerian and African stones can cut beautiful finished gems that rival Afghan material. From my experience I don't think quality is even questionable as I still haven't seen any Tourmaline Floor me like the Best Afghani material in its natural crystal form! Afghan Tourmaline can cost an arm and a leg and Nigerian material is a great affordable substitute for everyone to have fun faceting some Tourmaline.
