WOWW! Another of natures masterpieces. This was part of 2 inter-grown crystals that naturally produced a HEART pattern in the stone. The stone looks roughly 70% clean while the remainder has some minor inclusions. YES, this can be faceted; however, this is an AWESOME piece for a creative jewelry project or just to keep as is. I think this would make a lovely suite of Slices that could be strung up into earrings showing the Heart pattern inside. I've never seen anything quite like this from Nigeria and I have seen quite a lot of Tourmaline in my time. Even the colors on this are PERFECT!
