Engraving Gemstones

I make my jewelry and have come up with an idea for a particular
piece that I’m doing, which would include the stone that I have
chosen for the piece to be engraved. I don’t have the capability
myself and was looking for a company that specializes in this medium
(engraving stones).

I would like to do a pilot piece. Based on the finished product, I
would be interested in creating a line of that one piece and was
hoping that you could either assist me in this effort or point me in
the right direction.

Thank you, in advance, for getting back in touch with me.
