18K White Gold Vs Platinum

White Gold vs. Platinum Density. Platinum is a very dense metal and much heavier than gold. Platinum is about 60 heavier than 14K gold and about 40 heavier than 18K gold. So, if you have a ring made of 18K white gold and an identical sized one made of platinum, the platinum ring will be almost one and half times heavier than the white gold ring.
