Platinum sat above gold for most of the 20th century — since 2015 it's mostly traded at a discount. It's used mainly in catalytic converters and high-end jewellery (the Platinum 950 alloy is the standard for premium engagement rings). Below: the live UK price plus per-purity values for jewellery and bullion.
All values use the live spot above. Per-gram = (spot ÷ 31.1035) × purity. Per troy ounce = spot × purity.
