What is White Gold
White gold is nothing but YELLOW gold mixed with some other metal so basically it is an ALLOY of gold made by mixing GOLD with another metal usually nickel, manganese etc. Sometimes copper, zinc or silver are added. The purity unit remains the same i.e. KARAT.
The most popular and common application for white gold is in the use of jewellery items. White gold jewellery includes such items as earrings, necklaces, ankle bracelets, and rings.
Pure gold as such is too soft to make jewellery by itself, manufacturers mix pure gold with other metals before shaping it into any jewellery product. These other metals contribute to the gold’s colour. White gold is an alloy of pure gold and white metals, such as palladium, platinum, or silver. Originally is DULL what makes it shine is Rhodium plating then gives the white gold its bright white colour; pure white gold without plating actually looks light gray.
White gold contains nickel alloys, but nowadays most manufacturers don’t use nickel to create white gold because one-in every eight people is allergic to nickel. If you are allergic to nickel, use caution buying second-hand white gold. People often get rashes if they are allergic to nickel for instance, If you notice a small rash around the area of the jewellery, it could be because the white gold contains nickel and that you are allergic to it, so it is recommended that one should be careful before buying white gold and see that he/she is not allergic to it.
Yellow gold of different karats differ in colour, easy to say that different quality gold will have different colour. But white gold of 10kt, 14kt, and 18kt usually looks the same because of the rhodium plating given to it for exclusive SHINE. However, one thing white gold actually differs is that in hardness, with 10kt white gold being the hardest of the lot. 18-karat White gold is the softest. It contains the most pure gold and is, therefore, the most expensive. By law, every piece of gold jewellery should bear a stamp declaring its weight in karats.
The properties of white gold differ according to the metal that is mixed with gold to form the alloy. White gold that is composed of a gold and palladium mixture will tend to be somewhat more pliable. The presence of nickel in white gold adds strength which is desirable for the creation of rings and other jewellery. The white gold that has nickel mixed will have a longer period of life and does not wear that easily. Rhodium as mentioned earlier provides the extra SHINE to the jewellery and also helps to protect the finish of white gold and also provide protection from scratching.
