Platinum vs White Gold
There are many precious metals such as gold, silver, diamond, platinum and so on. When it comes to engagement rings, people prefer platinum over other metals because of its sparkling beauty, elegance, whiteness, and durability. Though engagement rings can also be made of silver and gold but people like white rings studded with diamonds that add to the beauty of this white metal. However, white gold has become equally popular among people and jewelers and today there are more and more people opting for rings made of white gold. However, not many know about the differences between white gold and platinum. This article will explain these differences so as to enable people to go for either of the two materials when it comes to choosing for their engagement rings.
For starters, white gold is not platinum. It is an alloy of the yellow metal (gold) with other precious metals such as silver or palladium to give it a whitish appearance. Both white gold and platinum have different properties and one must be aware of their features before finalizing either as the material for their engagement rings.
As told earlier, addition of other materials turns gold into an alloy known as white gold. White gold can be 18kt, 14kt or even 9kt depending upon added metals. When 75% gold is mixed with 25% other materials such as silver and palladium, we get 18kt white gold. As the percentage of gold goes down, so does it kt. In earlier times, it was common to use nickel for making white gold but since nickel causes adverse skin reactions, jewelers have stopped adding nickel for this purpose. To make a finished alloy whiter, a plating of rhodium is done. Rhodium has properties similar to platinum and makes ornaments look as white as platinum. However, rhodium plating is prone to wear and one should get rhodium plating done again after every 12-18 months to keep the ring looking white.
Many people prefer platinum over white gold though it is more expensive. It is a pure metal that is white in color and does not need any plating as it is very durable and long lasting. Platinum is denser than gold so a ring of same carats as gold feels heavier.
