White Gold Ring
White gold is gold that has been alloyed with other metals such as silver, palladium or nickel.
The color of white gold is actually light gray so white gold jewellery is often coated in a highly reflective substance known as rhodium. Also it may be coated in platinum or palladium.. This adds a brilliant shine so that what you see is not actually the white gold but the coating.
White gold of course is not as expensive as pure gold but might be expensive if coating with a product such as platinum which is, ounce for ounce, worth almost double the value of gold.
White gold rings are probably more popular with men than with women who tend to prefer the glitter of gold or the sparkle of diamonds.
When buying white gold rings ensure you get a certificate or a guarantee that it is actual what gold you are buying. A certificate that describes exactly what you are getting, in fact, not just the white gold but what the alloy is and the carat and what the coating is if any. (You can tell if there is a coating or not. If not the metal will look grey and dull, if it is coated it will look shiny and bright)
A white gold ring is very nice and a good way to preserve some assets in the long term. It is usually purely for decoration however which is how most people will wear it.
