One of the questions that we are often asked is, what is the difference between White Gold and Platinum? Here’s our guide to the two metals.
Platinum is a naturally white metal, whereas white gold is naturally a light grey / yellowish colour and has to be plated in another metal called rhodium to make it whiter. Platinum is approximately 40% heavier than gold.
Platinum is 30 times rarer than gold, so its price is invariably that much higher.
Platinum is generally 95% pure platinum compared with gold which is 75% pure gold.
Platinum is harder wearing than gold due to its density and weight. It does scratch like all other precious metals, but a scratch is merely a displacement of metal and none of its volume is lost.
If white gold has been rhodium plated, the colour difference between white gold and platinum is not noticeable. The two will look almost identical when new, however the rhodium plating will wear off over time leaving the metal looking slightly yellow in colour.
Palladium is a noble metal and within the platinum group of metals. Palladium is internationally recognised as being a precious metal. Palladium is naturally white, like platinum, and therefore does not need to be rhodium plated to give it a white appearance and it does not tarnish.
Palladium is much less expensive than platinum. The main reason for this is that palladium is far less dense than platinum (palladium has a density similar to silver), and feels very light in your hand. Palladium is a good alternative for men’s wedding rings as it is a cheaper alternative to platinum with essentially the same appearance.
We use 18 carat and. 18 carat yellow gold is 75% pure gold with 25% alloy metals including copper and zinc.nlike white gold, which needs to be rhodium plated to look white, yellow gold does not require plating as it is naturally yellow. Yellow gold is hard wearing and will maintain its yellow colour, but it always looks best once it has been polished.
