White gold jewellery

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 color.
Jewelry in its most basic form has been used since the dawn of of man's use of tools and clothing. Until recently, researchers had believed that the ability to use symbolism did not develop until humans had migrated to Europe 35,000 to 40,000 years ago. Recently discovered mollusk or nassarius kraussianus shells that had been perforated to be made into beads are now thought to be some of the oldest known man-made Jewelry. This mollusk jewelry was discovered in a cave in Blombos, South Africa, and dates back to the Middle Stone Age 100,000 years ago. Other readily available natural materials used to make the first jewelry include animal teeth, bone, various types of shells, carved stone and wood. Most likely, jewelry started out as a functional item used to pin articles of clothing together and was later adapted to a purely aesthetic adornment.
Used as a symbol of wealth and/or status as well as to protect against harm, ward of evil, and heal ailments, jewelry was used to adorn nearly every part of the body and has been made out of almost every material known to mankind.

Care of white gold:


White gold is looked after more or less the same way as yellow gold products. It has a thin layer of rhodium plating, which can wear off after continual use. This can be prevented by rhodium plating the white gold products after at least every six months. A little effort will keep your white gold jewelry in perfect condition.
