Definition

Fine silver is pure silver with a minimum content of 99.9%, often stamped 999. It is the purest form of silver used in jewellery and has a bright, white lustre that tarnishes far less readily than sterling. The trade-off is softness: at this purity silver marks easily, so it is not well suited to rings or bracelets that take daily wear. Most jewellery is made from sterling silver, 92.5% silver alloyed with copper for strength, though fine silver is used for PMC work, some beads and decorative pieces.

Frequently asked questions

What is the difference between fine silver and sterling silver?
Fine silver is 99.9% pure silver, while sterling silver is 92.5% silver mixed with 7.5% other metal, usually copper. Sterling is harder and more durable for wearable jewellery; fine silver is purer but softer and better suited to less-worn pieces.
Does fine silver tarnish?
It tarnishes much more slowly than sterling silver because there is no copper in the alloy to react with air and moisture. Over time it can develop a slight darkening, but it is far less prone to the black tarnish common with sterling.
What does 999 silver mean?
The stamp 999 indicates 999 parts per thousand, or 99.9% pure silver. It is the standard hallmark for fine silver, in the same way that 925 marks sterling silver at 92.5% purity.
