Frequently asked questions
What is sterling silver?
Sterling silver is 92.5% silver by weight. A 925 stamp indicates the nominal silver fraction.
How much fine silver is in 50 g of sterling?
50 × 0.925 gives 46.25 grams of fine silver.
How is 999 silver valued?
Multiply the alloy weight by 0.999 and the spot silver price per unit of weight.
Can I weigh a sterling knife as a single piece?
Use only the silver alloy weight. Some knives have steel blades or filled handles.
Can I use this for silver-plated flatware?
No. This calculator requires known bulk purity. A sterling setting would overstate the silver content of a plated item.
