Frequently Asked Questions
What is 950 Platinum?
950 Platinum means the metal contains 95% pure platinum and 5% other metals (usually ruthenium, iridium, or cobalt) to add strength.
This high purity makes platinum rare, valuable, and ideal for fine jewellery, especially engagement rings and wedding bands.
Why is Platinum Denser & Stronger than Gold?
Platinum is naturally denser and heavier than gold, which means:
It feels more solid and substantial
It is more durable for daily wear
It holds gemstones more securely
Unlike gold, platinum does not wear away easily—when scratched, the metal moves instead of being lost, helping jewellery last for generations.
How is Platinum Purity Measured?
Platinum purity is measured in parts per thousand:
950 Platinum = 95% pure platinum
900 Platinum = 90% pure platinum
Jewellery is usually stamped with “950 PT” or “PT950”, confirming its purity and authenticity.
What makes platinum different from white gold?
Platinum is naturally white, while white gold is created by mixing yellow gold with other alloys and coated with rhodium to appear white. Over time, white gold may require re-plating, but platinum maintains its natural sheen forever. It’s purer, denser, and more durable — making it a superior choice for timeless jewellery.
Does platinum lose its shine or fade over time?
Never. Platinum does not tarnish, corrode, or lose color. With daily wear, it may develop a soft patina — a gentle luster that enhances its character and vintage appeal. If desired, professional polishing can easily restore its mirror-like finish.
Is platinum suitable for everyday wear?
Absolutely. Platinum’s strength and density make it ideal for daily wear. It resists scratches better than other metals and keeps gemstones secure in their setting. That’s why platinum is often chosen for engagement rings, wedding bands, and heirloom pieces meant to last a lifetime.
Why is platinum more expensive than gold?
Platinum is rarer and denser than gold — it takes more metal and craftsmanship to create the same piece. Additionally, platinum jewellery is typically 95% pure, compared to 18K gold’s 75%. This combination of rarity, purity, and resilience makes it more valuable both materially and sentimentally.
How do I care for platinum jewellery?
Platinum is low-maintenance and easy to care for. Clean it occasionally with mild soap and warm water, and gently polish with a soft cloth. For deeper cleaning or restoring brilliance, professional polishing at SBM can return your piece to its original radiance — without any loss of metal or purity.
