Various sizes of White lab created sapphire/corundum rough for faceting and gemstone creation.

As decent #12 corundum boules become increasingly scarce due to reduced production, I was able to find these cylinder cores. They are most likely cored from Kyropoulos-grown sapphire boules. These pieces will make excellent cut gemstones, giant doorknob gems, a D20 die, or serve as fascinating discussion pieces in their current form. Some have minor chips along the edges.

Length: 20mm - 210mm
Diameter: 23mm - 60mm
