stunning Mexican alpaca silver bracelet w/ abalone

I'm not sure how old this beautiful hinged bracelet is, likely vintage, but it is definitely stunning. The bracelet is stamped "Mexico" and what appears to be "silver 925" yet it did not test as sterling on an acid test. I will definitely update with the metal content if I can get an XRF analysis for it! Regardless, the piece is substantial, with shades of purple, blue, pink and gray in the abalone inlays, each with a beaded bezel setting. This bracelet is from an estate sale and is in good vintage pre-owned condition, with a bit of surface scratching (primarily on the back) and normal wear. Circumference (with clasp closed) approx. 6.5" Width approx. 1" Weight approx. 30 grams Comes from a smoke free home. Bundle this with other items from my closet for a discount! Reasonable offers are welcome.
