What is platinum in jewellery?

Definition
Platinum is a naturally white, very dense precious metal found in small quantities in South Africa and Russia, and it has been prized for fine jewellery since the early twentieth century. It is harder to work than gold and considerably heavier, which gives platinum pieces a satisfying weight and solidity. Because platinum is naturally white and does not fade or tarnish, it never needs rhodium plating, and its density means claws and settings stay strong over time. It costs significantly more than gold, both for the raw metal and to work with.
Frequently asked questions
- Is platinum better than white gold?
- Platinum is denser, stays naturally white without re-plating, and is hypoallergenic. White gold is lighter, costs less and is easier for a jeweller to resize. Platinum is often recommended for engagement rings because the metal holds stones very securely for decades.
- Does platinum scratch?
- Platinum does scratch, and because it is dense, scratches show as a soft patina rather than lost metal. Many people grow to love this look. A jeweller can polish platinum back to a bright finish whenever you want.
- What purity is platinum jewellery?
- Most fine platinum jewellery is 950 platinum, meaning it is 95% pure, which is far higher than the gold content in 18ct gold. Some pieces are 900 or 850 platinum, with the remainder made up of metals like iridium or ruthenium for added hardness.
