I believe the stone on this lovely Taxco, Mexico bracelet is Chrysocolla or azurite which is found in California and Mexico. It's not cracked - natural seam shows up in photo. The bracelet was made by Sigi Pineda (circa 1960's?? - not sure) It's marked 277 w/Hecho en Mexico and Sterling stamps - plus a round "eagle or logo" stamp and Sigi Taxco. It has a security catch on clasp. Stone measures 1-1/2" square.
From what I read Sigi Pineda produced lots of sterling and stone jewelry.
I researched this particular bracelet about 5 years ago and found a black onyx for $375. but since then can't find add'l internet information. I bought this in 1995 San Diego consignment shop.
Any more information is greatly appreciated. Thank you!
