|Bracelet, stamped with a kachina symbol and STERLING,|
one of the marks used by
Maisel's Indian Trading Post of Albuquerque NM, mid 20th century.
The seller told me that the stones in both pieces are stabilized Kingman turquoise. If you don't want an answer plucked out of the air, don't ask. I guess all that matters is it's nice-looking turquoise, set in older mass-produced sterling silver for the tourist market.
