Awesome HUGE Chunk of Grape Green Nigerian Tourmaline Faceting Rough. We estimate that roughly 60%+ of this stone is Top Facet Grade with quite a bit of the remainder having additional Facet Rough potential; however, you will have to saw this piece along feathers to insure you get clean finished stones. There are nice LARGE CONTIGUOUS Clean sections in this piece and for the price we have on this you can't go wrong!!! We didn't bother to cob this stone as we didn't want to take the chance of it fracturing the wrong way and we DON'T saw. Ideally you should use a saw to take out the facet rough sections in this. 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.
