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.

55mm x 25mm x 6mm.   Weight: 50.80 carats.

Every one of my cabochons is custom cut to take the best advantage of the particular slab from which it is fashioned. Colors may vary somewhat from what is pictured due to differences in computer monitors.
