Comments:
This is the second of two available lots of vanadium kornerupine facet rough. This one has a nice range of color tones, including a richly emerald green piece.
One of the pieces is silky, but free of other inclusions or problematic fractures.
This parcel of 5 pieces is a blind pour from my 2 to 2.99 ct stock, and they're all well shaped for decent to good yield.
This is a great group of pieces for this incredibly rare gem material. It was last found, and depleted between 2019 and 2021. All new material has ceased. The only available kornerupine out there now comes from old collections trading hands, or material being dug out of the back of a safe somewhere.
