Originally, white gold was developed to imitate platinum as it is cheaper.It has become increasingly popular since then.It has come to be used more extensively than pure yellow gold in the recent times.
No real white Gold
You will be surprised to know that there is no such thing as white gold!However,there are some gold alloys which appear white, silver or grey. When some people speak of white gold, they mean white gold alloys. There is no such thing as naturally occurring white, rose or green gold. Gold itself is only one color – yellow. All these “colors” of gold are created by mixing pure 24K yellow gold with other metals. The percentage of these other metals produces the different shades of gold.White gold is generally created by increasing the silver-colored alloys (zinc, silver, nickel) and mixing with gold and decreasing the yellow-colored alloys .White gold is usually derived from yellow gold by using palladium, nickel, or zinc in the alloy to reach a white color.
14k white gold contains 14/24 gold, and the rest is comprised of the alloys that give gold its white color. If stamped 18 karat, it would be 75% pure gold.
White gold is used to make all types of jewelry, from rings to bracelets and from white gold chains to necklaces. White gold is the preferred choice of many when using white jewelry because it does not tarnish like silver and it is less expensive than platinum.It can also be combined with yellow gold to make two-tone gold jewelry.Two toned gold jewelry has become extremely popular in recent years.
White Gold is produced by mixing yellow gold with Nickel and Palladium:
White Gold Alloys with Nickel
White gold became fashionable in the 1920’s.it was used mainly as a substitute for platinum.Because platinum is quite expensive, needs greater temperatures than gold, and it is generally considered harder to work with when compared to gold, although it is ideal for use in diamond settings.
The commonest metal which causes a significant bleaching effect in gold is nickel. It is quite inexpensive, and also provides, in 18 carat alloys, a good color match for platinum.But its color matching in 14 and 9 carat alloys is poor.
White Gold Alloys with Palladium
The other metal which is ideal and commonly used as a constituent of white gold alloys is palladium, which is a close relative of platinum. But its main disadvantage is that it is quite expensive.
White Gold Versus Platinum
Eighteen-carat white gold consists of 75% gold mixed with 25% white metals. White gold rings are usually coated with a hard protective finish of rhodium, a silver-white metal like platinum. Like normal yellow gold, white gold glitters in a variety of carats: 18ct, 14ct, or 9ct. Platinum is an entirely different element .It is a white metal that is denser, heavier, and longer-wearing than gold. It is mostly used in its pure form and does not require a protective coating. But Platinum is quite expensive compared to white gold. A platinum ring is perhaps twice the price of a similar ring that’s made in white gold.
