Sounds like the jeweler wouldn't know the difference from a diamond and
a piece of quartz. The stones aren't turquoise,they are azurite
malachite which occurred in most of the SW copper mines. The bolo looks
like it was made by a hobbyist and not NA.
It's a "marriage" piece,early commercial/trading post piece.Center piece
replaced after being"lost" cracked band in center.Center piece replaced
with Mexican travertine carving.
