Over the years, metal trends have changed and we have been following them closely.
In the 1990’s over 85% of fine jewellery sold with white precious metals at the company were sold in 9/18k White gold. This was predominantly because platinum production is capital intensive and needs production facilities to make large capital investment to cast and manufacture jewellery in 95% pure platinum.
The consistent issue with white gold came to the fore front as historically nickel was one of the alloys used in 9k (37.5% pure) &18k (75% pure) white gold production and nickel at times can be sensitive or harmful to skin. As this was highlighted, the alloy moved from nickel to palladium or silver and currently all white gold production has to be nickel free. Some lower end jewellery retailers cannot afford to use palladium and they use substitutes like silver which does change colour over time.
As we all know, gold is inherently yellow and over time and persistent use, any alloy gives way and the item will change colour or tarnish. Gold is usually coated with rhodium in jewellery to give its white lustre, this coating wears off over time as well, hence jewellery made with 9k and 18k white gold needs to be re-plated from time to time at an additional cost.
At Marlow’s we have recently advised customers to opt for platinum over 18k white gold in their everyday jewellery. Our platinum is 95% pure and will not generally change colour unless the skin comes in contact with chemicals which rarely happens.
Further, platinum is a heavier metal that 18k White gold so like for like, an item in platinum will be heavier than 18k White gold and far heavier than 9k White gold. This provides for a longer lasting metal. As the metal is harder than 18k gold, platinum is generally more difficult to work with and even though it should not change colour, small blemishes and scratches may commonly appear over time, which may need a clean.
If you are in search for a white precious metal jewellery, our recommendation is to opt for platinum instead of 18k White gold for longer lasting whiteness. If you are opting for a gift item, choose 9k White gold and if possible combine it with one of our aftercare products to make sure your gift sparkles for years to come.
