On cutlery, "sterling" means the item is made from sterling silver, a specific and legally defined alloy.
Understanding Sterling Silver
Sterling silver is not pure silver. Pure silver is too soft for practical use like cutlery. To make it durable enough, it is mixed with other metals, primarily copper.
Based on the standard, sterling silver is an alloy composed by weight of 92.5% silver and 7.5% other metals, usually copper. This composition gives it the necessary strength and resilience for everyday use while retaining the beauty and prestige of silver. The sterling silver standard has a minimum millesimal fineness of 925, meaning 925 parts per thousand are pure silver.
Why Use Sterling Silver for Cutlery?
- Durability: Adding copper makes the silver much harder and more resistant to bending and scratching than pure silver.
- Workability: The alloy is still pliable enough for artisans to shape and engrave intricate patterns.
- Lustre: It maintains a beautiful shine characteristic of silver.
Identifying Sterling Cutlery
Genuine sterling silver cutlery is typically marked with a hallmark indicating its authenticity and fineness. Common markings include:
- "Sterling"
- "Sterling Silver"
- "925"
- "925/1000"
- Hallmarks from assay offices (e.g., lion passant for British sterling)
These marks guarantee that the metal meets the 92.5% silver standard. Cutlery marked "silverplate" or "EPNS" (Electro-Plated Nickel Silver) is different; it is a base metal with a thin layer of silver applied to the surface.
