What is Sterling Silver? The Science of 925 Silver Explained
A P Jewellers
When shopping for silver jewellery, you will frequently see the stamp "925" or "Sterling Silver". But what does this mean scientifically?
Understanding 92.5% Purity
Pure silver (99.9%) is extremely soft and malleable, making it impractical for everyday wear. To give it structural strength, pure silver is combined with 7.5% copper. This specific composition creates 925 Sterling Silver—the international standard for fine jewelry durability.
How to Identify Genuine Sterling Silver
Always inspect the ornament for a tiny "925", "S925", or "Sterling" hallmark stamp, which certifies its authentic composition.
