You probably don't want dyed, stabilized, reconstituted, etc. beads? Antique or new?

Also, I have found there are many colors of "turquoise" so perhaps you can post an image of the particular shade. I've seen everything from robin's egg blue to sky blue to deep dark green-blues.

The only person I'd trust for turquoise beads at the moment is Danny. However, you must be prepared to pay handsomely for gem quality turquoise beads, if that's what you're after.

It would help if you gave your requirements for size, shape and number of beads. Someone may have what you are looking for in their stash.
