Sonora Sunrise - Custom piece

I was asked if I could drill holes in a stone.  Well - I'm not really equipped to do a good job at drilling, only having a Dremel hand power tool and 1.5mm diamond drills to work with.  No drill press to ensure a straight hole, no water flow to keep the diamond tool cool.  Anyway.... here are a few images to show the transformation from the rough cut slab to a finished double sided Sonora Sunrise cabochon

Saw cut slab, rough ground.  You can see the ink line at the edge and two dots where the holes will go.

The slap is 6.5mm thick - thin for such a large cab - especially double sided

finished - one side

the other side
