950 jewelry stamp
In a 950 jewelry stamp, 950 SILVER is silver above sterling fineness. EPNS and ALPACA describe different base-metal constructions from sterling.
Reading the metal designation
PT950 or 950 PLAT is platinum. 950 SILVER is silver above sterling fineness. Do not interpret the number from the white colour of a ring: white gold, silver, platinum and palladium can look similar.
What to check next
EPNS and ALPACA describe different base-metal constructions from sterling. A silver standard can still appear on a gilded silver object. Check the mark on the main piece as well as detachable fittings, then use the separate signature to look up its maker.
