How to Identify Real Platinum? 4 Expert Tips to Spot Genuine Pieces
6 June 2025
Platinum is one of the most luxurious and sought-after precious metals, known for its natural silver-white hue, exceptional durability, and understated elegance. However, its high value also makes it a target for imitation using white gold or platinum-plated materials. In this article, we'll share 4 practical tips to help you verify the authenticity of platinum jewellery and shop with greater confidence.
Tip 1: Check for Platinum Hallmarks (e.g. Pt950, Pt900)
Authentic platinum jewellery should feature clear markings such as "Pt950," which means it contains 95% pure platinum. Other common marks include "Pt900" and "Pt999." These hallmarks are usually engraved on the inner band or edge of the piece. If the item lacks a clear hallmark, it's a red flag.Note: Be aware that counterfeit items may include fake markings, so hallmarks should only serve as a preliminary reference. Use additional methods for confirmation.
Tip 2: Assess Weight and Density
Platinum is significantly denser than most metals, making it noticeably heavier. Among precious metals, it has one of the highest densities. When comparing two similar-sized pieces, a platinum ring should feel heavier than one made of gold or silver. If the item feels surprisingly light, it might not be real platinum.Quick Test: Compare with a gold ring of similar size to feel the weight difference.
Tip 3: Observe Colour and Shine
Platinum naturally has a soft, white lustre and does not require rhodium plating to maintain its colour. It has a refined, subtle glow that remains stable over time. In contrast, white gold may appear brighter but requires plating, which can wear off.Visual Clue: Lay platinum next to silver or white gold. Real platinum will have a more subdued, elegant sheen.
Tip 4: Seek Professional Testing
If in doubt, have the piece professionally tested by a jeweller or an independent gem lab. Common testing methods include:- XRF (X-ray fluorescence) analysis: Quickly identifies metal composition without damaging the piece.
- Density testing: Verifies whether the weight-to-volume ratio matches platinum’s characteristics.
- Fire assay testing: A precise but advanced method carried out by professionals.
Platinum vs White Gold: Know the Difference
Many confuse platinum with white gold, but their properties differ significantly:| Feature | Platinum | White Gold |
|---|---|---|
| Composition | Pure platinum (e.g. Pt950) | Gold mixed with white metals (e.g. nickel or palladium) |
| Colour | Naturally white | Slight yellow tint, rhodium-plated |
| Purity | Typically 95% | Typically 75% (18K) |
| Price | Higher | More affordable |
| Durability | Very durable and dense | Softer, more prone to wear |
