Various sizes of discontinued Djeva made Dark Green lab created sapphire/corundum rough for faceting and gemstone creation..
The Swiss company Djeva, is no longer producing any lab created corundum. As such, Djeva made corundum will become more and more difficult to come by. Get yours while it lasts.
Each split boule is listed for sale by weight and will typically vary in size within the following ranges:
Length: 40mm - 50mm
Width: 12mm - 17mm
Thickness: approximately 6-8mm at the base
Green is a difficult color to produce.
