Hi,
There's a local company that does custom gemstone faceting etc and I checked out their website www.atlasgemsinc.com

The music is annoying after a short while but I saw a photo of something and was wondering what it is.
What is happening in this snipping tool jpg?    Are they polishing or faceting or what??

Looks like a concave facet machine.

Nice looking Lapis Lazuli necklace in their web information.

I know....that must have been a trick to get the lapis beads to be graduated in size but have that gray band fall in the same spot throughout the graduation.
Nice work eh??
