Understanding Platinum
A dense, naturally white precious metal used for fine jewellery and secure stone settings.
What Is Platinum?
Platinum is a naturally white precious metal known for density, corrosion resistance and suitability for fine jewellery. Because it is dense, two similarly sized rings can feel noticeably different in weight if one is platinum and the other is a lighter alloy.
Platinum Fineness
Common platinum jewellery is 950 fineness, meaning 950 parts platinum per thousand, although UK hallmarking standards also recognise other platinum fineness levels.
In the UK, platinum articles described as platinum generally require a recognised hallmark when the precious-metal weight is 0.5 gram or more, subject to statutory exemptions.
Platinum and White Gold Are Not the Same
Platinum is naturally white. White gold is a gold alloy created using white-coloured alloying metals and is often finished with rhodium plating to produce a bright white surface. Their maintenance, density and price structures can therefore differ.
Gold, silver and platinum are distinct precious metals even where their finished colour looks similar.
Patina and Wear
Platinum can develop a soft patina as the surface acquires microscopic wear. Some customers like this appearance; others prefer periodic professional refinishing. Any work should take account of the design, stones and original finish.
Frequently Asked Questions
Does platinum tarnish like silver?
Not in the same way. It can develop surface wear and patina rather than typical silver tarnish.
Is platinum heavier than gold?
Platinum is very dense, so a similarly sized item can feel heavier, though the actual weight depends on design and alloy.
Do you buy platinum?
Yes, subject to testing and assessment.
