Why Platinum Stands Apart
Platinum sits apart from gold in almost every physical property. It is roughly 30–40 times rarer than gold, significantly denser — a platinum ring feels noticeably heavier than an equivalent gold ring — and it is naturally white. Unlike white gold, which achieves its colour through alloying and rhodium plating, platinum's whiteness is inherent. It does not fade, discolour, or require re-plating.
Jewellery-grade platinum is typically 95% pure (marked 950Pt), with the remaining 5% composed of palladium, ruthenium, or cobalt to improve workability. This high purity is why platinum is the preferred metal for allergy-sensitive clients.
Sara works with platinum for commissions where these properties matter most: engagement rings and wedding bands that will be worn daily for decades, settings for precious stones where metal security is paramount, and pieces destined to become heirlooms.
Naturally White
Platinum's white colour is intrinsic, not applied. It will never yellow or require rhodium re-plating, unlike white gold.
Hypoallergenic
At 95% purity with no nickel in the alloy, platinum is the safest choice for those with sensitive skin or metal allergies.
Exceptional Density
Platinum is approximately 60% heavier than gold of the same volume. This density also makes it more secure for stone settings.

Both metals achieve a similar white appearance, but they differ significantly in composition, maintenance, weight, and cost. The right choice depends on your priorities.
| Property | Platinum (950Pt) | White Gold (18ct) |
|---|---|---|
| Colour source | Natural | Alloyed + rhodium plating |
| Purity | 95% | 75% |
| Weight | Heavier | Lighter |
| Hypoallergenic | Yes (no nickel) | Usually (check alloy) |
| Requires re-plating? | No | Every 2–4 years |
| Patina over time | Yes — polishable | Minimal |
| Cost | Higher | Lower |
Sara discusses these differences honestly at your consultation and can show you sample pieces in both metals so you can feel the weight difference for yourself.
Designing with Platinum
Platinum suits certain jewellery types and settings particularly well. Its density and strength make it the preferred metal for prong and claw settings — the claws hold their shape over time and provide a more secure grip on stones than lighter metals. For solitaire engagement rings, where the integrity of a single setting is everything, platinum is Sara's most common recommendation.
Platinum also works beautifully with colourless diamonds — the naturally white metal allows a D-colour diamond to appear at its purest — and with pale-toned stones such as aquamarine, white sapphire, and light-coloured morganite. The absence of any warmth in the metal lets these stones speak for themselves.
One characteristic worth understanding is platinum's patina. Over time, and with daily wear, platinum develops a natural soft sheen — its surface becomes slightly less mirror-bright. Many clients appreciate this effect, reading it as evidence of a life lived in the piece. It can always be professionally polished back to a bright finish; Sara can do this as part of an annual service check.
Platinum and Jewellery Remodelling
Platinum can be remodelled, but it is a more technically demanding process than working with gold. It requires higher melting temperatures and specialised equipment. Sara's studio is set up for platinum work and has remodelled inherited platinum pieces — converting an old-fashioned setting into a contemporary design, or combining the metal from two pieces into one.
If you have inherited platinum jewellery that you don't wear, Sara can assess it and discuss whether remodelling is practical for your piece. You can learn more about the jewellery remodelling process here.
Caring for Platinum Jewellery
- Clean with warm soapy water and a soft brush — platinum is low-maintenance and does not require specialist products
- Rinse and dry thoroughly with a lint-free cloth after cleaning
- Remove before activities that involve impact, heavy chemicals, or chlorine
- Store separately to prevent scratching from harder materials
- Have settings professionally checked annually to ensure prongs remain secure
- Polish professionally when desired to restore a bright finish — Sara can do this during a service appointment
