What is white metal in jewellery?

Definition
White metal, in a jewellery context, is a broad term for low-cost alloys made from non-precious metals such as tin, lead, antimony and bismuth, which produce a silvery-coloured base used in costume and fashion jewellery. It is sometimes called pot metal, pewter or Britannia metal depending on the exact composition. White metal pieces are often plated in silver, rhodium or gold to improve their appearance, but the base itself has little intrinsic value, and the plating tends to be thin enough that it will wear through with regular use.
Frequently asked questions
- Is white metal safe to wear?
- Most modern white metal jewellery is safe, though older or very cheap pieces may contain lead, which is a concern for pieces worn against skin for long periods, particularly for children. If you are unsure about the composition of a piece, choosing hallmarked precious metal jewellery removes that uncertainty.
- How can you tell if something is white metal versus sterling silver?
- Sterling silver is hallmarked with a 925 stamp, and it is heavier and more expensive than white metal. White metal pieces are often lighter, may feel a little hollow, and can show patchy discolouration over time. The absence of any hallmark is a strong indicator that a piece is a base metal alloy.
- Why is white metal used in jewellery?
- It is inexpensive to cast, takes detail very well and accepts plating easily, so it allows intricate and decorative designs to be produced at a low cost. For fashion and costume pieces where longevity is less important than appearance, white metal is a practical base material.
