Hi Sheila what a lovely Bracelet! I like the hinged stationed too.
Yes, Peruvian bracelet, sterling silver, R130596 will either be a registration number, patent number of design number. The only way to positively identify the yellow metal is by testing it. Here is the best gold tester on the market.
It's easy to use but a bit pricey, although if you sell jewelry on a regular basis, it's worth every penny. This gold tester will also tell you the composition of the gold.
The other alternative is to take the bracelet to your local jewelry and let them test it, to determine if the metal is gold or not.
