Gold is not only white, yellow, red and pink. We will introduce you to its most incredible shades, which you did not even know about.
When it comes to gold, many people immediately imagine a sunny-colored metal. But what is interesting is that it can have a more interesting and unusual color. Today we will talk about all the colors of gold that are used in modern jewelry production.
It is considered a classic bright yellow gold. Such a beautiful rich shade is obtained by melting the precious metal with silver and copper. This is because pure gold is very soft and brittle, and it must be mixed with other metals. And the brightness of yellow gold depends entirely on the addition of silver to it. The more it is in the finished product, the brighter the gold shines.
Jewelry houses are increasingly turning their eyes to the side white gold. It is ideally combined with diamonds and pearls, emphasizing the beauty of precious stones. It is obtained by mixing yellow gold with palladium and platinum.
Until 2000, nickel was actively used to create a white tint, but then it turned out that it causes allergic reactions in many. Therefore, its use in precious alloys was discontinued.
Red gold was very popular in Russia in the 19th century. Such a metal is obtained when pure gold is mixed with copper and zinc. And the higher the copper content, the richer the shade. For a decorative effect, palladium is sometimes added to red gold to give it a slightly brown tint.
rose gold looks very elegant and impressive. For these qualities, jewelry designers who create wedding jewelry collections fell in love with him. Today, it is rose gold jewelry that sets the trend in jewelry fashion.
It turns out a delicate pink color due to the synthesis of gold, silver and copper. There is very little silver in this alloy, it is added to soften the shade and give the finished product a pleasant sheen.
Chocolate gold appeared on the jewelry market not so long ago. According to one version, its creator is the famous jeweler Fawaz Gruosi, the founder of the de Grisogono brand, who often experiments with the shapes, materials and colors of jewelry. The jeweler does not disclose his technology for obtaining such a shade.
It is only known that brown gold is obtained by fusing red and rose gold of various samples. Then it is treated thermally and chemically, gradually oxidizing until the coveted brown color appears on its surface. Experts are of the opinion that nickel, manganese, iron and copper help to achieve this effect.
Perhaps the most mysterious alloy is black gold. To make such a metal, a lot of resources are required, and the process of obtaining black gold is very complicated. It can be obtained in several ways, but the most popular is the method of alloying pure gold with chromium and colbat. The resulting material is then oxidized and treated at high temperatures (700 to 950 degrees Celsius).
Green gold is an incredibly beautiful metal, but not all of its variations are safe for health. The classic version is made of gold, copper and silver. The higher the silver content, the more delicate olive color the finished product acquires. To give gold a rich green color, cadmium, potassium and zinc are used.
True, such products are characterized by increased fragility and can cause severe allergic reactions. So green gold is often used by craftsmen to create masterpieces of the highest jewelry art, which are usually admired at professional exhibitions.
Purple gold is often referred to as purple or amethyst gold for its interesting lavender hue. True, as an independent metal from which jewelry is made, it is not used. He is the most fragile of all. Therefore, it is used as decorative inserts in jewelry, and it is obtained by mixing gold and aluminum.
Blue and blue gold
Blue has been one of the favorites in the jewelry world for several seasons in a row. This could not but affect the color of gold. Blue and cyan metal is rarely used in the jewelry industry and is not easy to obtain.
The main way to obtain gold of this unusual color is by alloying gold with indium (approximately 46% gold and 54% indium) or with gallium (56% gold and 44% gallium). Strictly speaking, the resulting material is not an alloy: gold enters into a chemical reaction with these metals and forms a new chemical compound.
At the same time, its physical properties change - blue gold is much more fragile, therefore it is used only for decorative elements of the product. It is hard to work with it - it requires experience and special skill, so not every jeweler undertakes to use it.
The combination of gold with indium gives a richer and deeper blue color, and with gallium - a gentle, sky blue.
Blue gold Antoniassy
The well-known jeweler Antoniassy from Argentina, at the beginning of the 20th century, discovered a way to obtain a blue-colored alloy that contained 90% gold (unlike modern methods). Gold acquired a hue due to microscopic inclusions of cobalt. To confirm the samples of metals, according to international rules, the jeweler was forced to disclose and publish a list of all components included in the alloy. But at the same time, he hid all the nuances of the technological process of production.
Until now, modern jewelers have not been able to obtain blue gold using the Antoniassy method according to his recipe.
