Choosing the Best Gold Watches
The yellow color of gold has always been attractive. Since time immemorial when gold was first discovered, it has always been considered a precious metal. Alchemists were beholden by its natural orange-yellowish coloring. They likened it to the shining sun. A very powerful tribute indeed considering the sun is essential to man.
The Alchemists refer to gold as aurum or Latin for shining dawn. Au is the atomic name of gold in the periodic table.
Gold's yellow warm color makes it unique. The jewelers today though are equipped with the technologies that could turn gold into various colors such as red, rose, light yellow, green and white gold.
Gold watches are highly-prized. The price of gold watches range from a few hundred dollars to millions of dollars depending on the quality or carat of gold used. Gold watches come in distinctive yellow hue of course.
But some gold watches are in white color. In order to attain this color, white gold watches are made up of gold plus one metal which could be silver, nickel or palladium. The white color of a white gold necklace is attained by careful selection of light metals which turns deep yellow of pure gold into white. White gold necklace is measured in karats, similar to its yellow gold counterpart.
For instance, an 18 carat white gold is made up of 75% gold and 25% alloy such as silver or palladium. 18 carat gold watches are also made up of 75% gold and 25% other metal such as copper or zinc.
Creating White Gold Watches
Creating white gold watches is just like mixing paint in order to have a lighter hue. Adding red metal such as copper will turn it to red. The same way, adding white metals such as silver, palladium, platinum or nickel will turn it to white. Only copper can turn gold to reddish or yellowish tinge among all the metals.
The process of turning gold into white is much similar to mixing paint to achieve the desired 'white' results. Adding red metal copper like copper will turn gold to red and adding white metals will turn gold to lighter color until it becomes white. All the alloying metals other than copper can turn gold lighter.
This process is called gold bleaching. The bleachers could turn the yellow gold to white. There are two strong bleachers of gold- palladium and nickel. The other bleachers have moderate to light effects compared to these two.
