Is white gold the same as platinum?
The answer to this question is no. White gold and platinum have their own properties which make them unique. The following white gold information and platinum information show you the difference between the two metals.
You will discover the difference between white gold and platinum and whether white gold or platinum is best for your needs.
White gold is an alloy of gold and some white metals such as silver and palladium. White gold can be 18kt, 14kt, 9kt or any karat. For example, 18kt yellow gold is made by mixing 75% gold (750 parts per thousand) with 25% (250 parts per thousand) other metals such as copper and zinc. 18kt white gold is made by mixing 75% gold with 25% other metals such as silver and palladium. So the amount of gold is the same but the alloy is different.
Traditionally nickel was used in white gold, however, nickel is no longer used in most white gold made today as nickel can cause reactions with some people. We do not use nickel in our white gold
When white gold rings are new they are coated with another white metal called Rhodium. Rhodium is a metal very similar to platinum and Rhodium shares many of the properties of platinum including its white colour.
The rhodium plating is used to make the white gold look more white. The natural colour of white gold is actually a light grey color. The Rhodium is very white and very hard, but it does wear away eventually. To keep a white gold ring looking its best it should be re-rhodium plated approximately each 12 to 18 months. Some people find this a bit tiresome and therefore opt for platinum.
Platinum is a white metal, but unlike gold it is used in jewellry in almost its pure form (approximately 95% pure). Platinum is extremely long wearing but does quickly have in our view a gray appearance but it does not need to be Rhodium plated like white gold.
Platinum is very dense (heavy), so a platinum ring will feel heavier than an 18kt gold ring.
Platinum is however generally more expensive.
