I'm trying to decide what to call the shape of this large freeform Nevada Rhyolite cabochon. If you rotate it 90-degrees clockwise, it resembles a bicycle racer's helmet, maybe? Very interesting appearance; the gray area down the right side is slightly softer than the rest of the cab, with a very slight difference in the polish. Very. Slight. Dimensions: 55mm x 25mm x 6mm. Weight: 50.80 carats. |
