Sterling Silver Rings

Unless it is over 100 years old or the hallmark has worn away, all fine jewellery should be hallmarked. The hallmarks 18K, 14K, 10K, 750, 585, and 375 indicate the purity of the gold. The numbers 950, PLAT, or PLAT are commonly used to identify platinum. The silver hallmarks 925, Silver 800, and Sterling are all well-known.
