As a result, diamond ring manufacturers and designers were unable to use platinum metals, which in turn urged them to figure out an alternative for platinum. Even though they tried several metals, only white gold metal was able to meet the quality standards of platinum. So, jewelers started to use white gold instead of platinum. White gold is actually an alloy, which is made by adding silver, palladium, nickel, and other metals to pure gold. The pale luminescence in most white gold diamond rings is achieved by plating their surface with rhodium. However, the rhodium coating in white gold diamond rings will wear away after a couple of years. So, you will need to replace the coating to maintain the brilliant white color of white gold diamond rings. Customers who are planning to buy a white gold diamond eternity ring should realize the fact that white gold is not that strong or durable as platinum. However, they are available to customers at a relatively lower price when compared to platinum, which is why these rings are immensely popular among budget shoppers. Moreover, white gold diamond rings are more scratch resistant too.
