More Kinds of Colored Gold
This week, we have been looking at different types of gold. Of the colored golds, white and rose gold are probably the more well known. However the gold family has many more hues. Experimenting with gold has led to products with a variety of colors and properties.
While white gold is created using an alloy of yellow gold and other metals, there are several methods for creating black gold. It can be created through electroplating or patination techniques. Both of these methods involve manipulating the surface of an object so that it appears different. The surface of gold and other metals can also be altered with lasers so that they appear black. Black gold can also be created with a chemical vapor deposition process.
Purple gold is often used as a gemstone because it is so very brittle and can shatter easily. Sometimes purple gold, which is made from an alloy of gold and aluminum, is also known as amethyst of violet gold. Because purple gold usually contains about 79% gold, it can technically be labeled as 18 carat gold.
Blue gold can be made from gold and indium. The alloys used to make rose gold can vary depending on how deep of a red is desired, while the alloy for gray (or grey) gold is often made with a specific formula. Gray gold combines silver, manganese and copper along with gold.
Green gold is made from an alloy of silver and gold. However, a different kind of green can be made when you sell gold to a gold buyer. Mix the little effort it takes to mail in gold to an online gold buyer with that gold buyer’s professional expertise and you end up with cash for gold. This is not an alloy or something for you to wear as adornment, but like some gold alloys, cash for gold is quite malleable in that you can spend or save it as you wish.
