plated sterling silver
In newer designs Ive seen where Ster/10K indicates that the ring is sterling silver, plated with 10K gold. In older designs, the 2 stamps usually mean that part of the ring is sterling and part of the ring is 10K gold.
PC on a 10k ring means the diamonds are real
I Believe It would be the ring being sterling silver with 10k black hills gold.
It tells you the proportion of gold in it.
