The Distinction Between 18K White Gold and Pt950 Platinum in Watches[/size]
18K White Gold and Pt950 Platinum are often confused but are entirely distinct metals with no direct relation. 18K White Gold, part of the 18K gold family, is an alloy primarily consisting of gold (750‰ pure gold) and a mix of white metals constituting the remaining 250‰, leading to its white appearance.
There are two main schools when it comes to the composition of these white metals in white gold. One adds zinc, resulting in a greyish-yellow tone that requires rhodium plating for that shiny appearance. Over time, as the plating wears off, the gold may appear dull, requiring re-plating which can be cumbersome.
The other approach involves adding palladium, a more costly method due to palladium’s status as a precious metal itself. However, palladium-enhanced white gold offers a lustrous, uniform white hue without the need for rhodium plating, simplifying maintenance. Despite the industry’s emphasis on the 750‰ gold content in white gold, manufacturers do not typically specify which white metal is added. Still, those in the know often prefer palladium-added white gold for its lasting beauty and ease of care.
Platinum (Pt950), representing the pinnacle of materials for watches and jewelry, stands significantly more expensive than gold. Often mistakenly called “white gold,” platinum bears no relation to gold. Only the most exquisite watches are crafted from platinum, reflecting in their premium pricing. For instance, a gold watch may sell for $20,000, while its platinum (Pt900) counterpart could range from $30,000 to $40,000, with Pt950 models reaching even higher. The 900 or 950 denotes the purity level of platinum, contributing to its elevated status and cost.
Understanding the differences between these metals not only enriches one’s appreciation for watch craftsmanship but also aids in making informed decisions when selecting a luxury timepiece.
