Ojewellery metal stamps: All of our our jewellery is stamped to indicate the fineness of the material it is made from.
Our silver jewellery under 7.78g is stamped with 925 for sterling silver. Our gold items under 1g are marked 375 for 9ct gold.
Our sterling silver items over 7.78g and gold over 1g are sent to be independently verified for metal quality. This is referred to as being assayed. A metal mark, referred to as a hallmarked, is applied as part of the assay process to verify the metal grade. Ojewellery is registered with the Birmingham assay office for this process.
The hallmark is made up of three parts:.
Part one: Our sponsors mark - the letters OJ in a hexagon.
Part two: The metal fineness grade - 925 for sterling silver or 375 for 9ct gold.
Part three: The Birmingham assay logo - an anchor.
