I saw your response to the question of undrilled gem beads, and
thought that you might be able to help with our dilemma. We are
developing a new bracelet which rely on an 8mm.gem bead( jade, lapis,
agate, etc.) with the center hole drilled out to 4mm. We have done it
ourselves, but do not have the equipment to do it properly. Anyone
know a supplier or process that would work?
