Mexican Retro Vintage Abalone Heart Cuff Bracelet

Pretty Boho heart design with inlaid abalone shell. 

• Size: Bracelet is 1 1/4" wide. Slightly adjustable with current opening of 2 1/4" in width. Inside diameter from end to end is 5".
• Type: Pre Owned Retro Vintage from the 1980's. 
• Condition: Darkened patina from age. There are two pieces of aligned shell. If viewed closely or under magnification you can see the line between them. I do not believe it is a crack because while the left side of the pieces align almost perfectly, the right side does not. That said, please inspect the photos as there is a line there regardless.
• Materials: Silver tone color metal alloy, inlaid abalone shell.
• Markings: Marked Hecho en Mexico on the back. There is also a small rectangle in gold color near where the bracelet is welded to cuff. It has what looks like tiny dots or circles in it which may or may not be a maker's mark of some kind.
