So I finally got my hand well enough to get back to cutting and finished the first of two calibrated 4mm stones for earrings for my daughter. This is the first one which comes in at 4.04mm.
This is the second attempt at cutting this stone, as the first one ended in failure when a fracture appeared in the center of the original rough.
The design for this cut was done by my son who wanted to try his hand at designing a cut. His design turned out great, and wasn't too hard to cut!
feel free to start a discussion with questions if you'd like. I'm still working hard to seed this community with content and try and get some additional people posting. :-)
