Platinum Hallmarks
950 platinum and the UK hallmarking rules for this dense white precious metal.
Platinum Fineness
UK hallmarking standards recognise platinum at 850, 900, 950 and 999 fineness. 950 platinum is especially common in fine jewellery.
Traditional Platinum Symbol
A traditional orb symbol can appear as an additional mark for 950 platinum, but a complete hallmark is identified by its required sponsor, fineness and Assay Office marks.
Very Low Compulsory Weight Threshold
Subject to other statutory exemptions, platinum articles described as platinum generally require a recognised hallmark when the precious-metal weight is 0.5 gram or more.
Platinum Is Not White Gold
Both can appear white, but the hallmark helps identify the precious metal. Platinum and gold have different recognised fineness marks and different metal properties.
