purity marking

**Purity Marking**

Purity marking refers to the official stamps or hallmarks applied to precious metals like gold, silver, and platinum, indicating their purity and authenticity. These marks serve as a guarantee of quality, helping consumers and jewelers verify the metal content and ensure they are receiving genuine products. Commonly found on jewelry and bullion, purity markings follow standardized systems set by assay offices or governing bodies and often include numbers (such as 925 for sterling silver or 750 for 18K gold), symbols, or letters. Understanding purity markings is essential for anyone buying, selling, or valuing precious metal items.
