|Another really simply cut native stone from Oro Verde, Brazilian citrine, and it is cut nearly deep enough and with sufficient angles to produce a clean stone with only a tiny "fish-eye" effect at the very bottom of the stone. The last two facets were cut slightly over the critical angle.
It is a very simple step cut on the top and bottom of the stone. It shows that you can find native cut stones that are reasonably cut if you look for them. A better than average native cut tone.
