Rare Naturally Etched Ametrine Crystal

Amazing rare ametrine crystal was naturally etched on the surface. When back lit it shows the beautiful zoned purple and orange of amethyst and citrine.  From what I understand, this was a small find in Bolivia that hasn't been commonly producing since the original find. We consider this piece to be a Large Cabinet (LGC) size specimen.
