All about purple gold
Recently, non-ferrous metals have become more and more popular. They attract attention with extraordinary combinations of shades, from which it is very difficult to look away. Today you can find products made not only from ordinary yellow, white or red gold, but also from black, blue and even green. Jewelry made of purple gold also looks interesting.
What it is?
Amethyst, purple or violet gold is an alloy that which includes not only common gold, but also palladium and aluminum. As a result of remelting, a fairly high-grade alloy of 18-19 carats is obtained, which is assigned a 750 standard.
The process itself is quite difficult and time-consuming, moreover, it is also expensive. After all, the melting point of each of the metals is different. So, for example, gold melts at a temperature of 1350 degrees Celsius. As for aluminum or palladium, a temperature of 600 degrees Celsius is sufficient to melt them. To obtain a beautiful lilac color, it is necessary to add at least 20 percent potassium to the alloy.
In the event that the percentage of potassium is less, the precious metal will acquire an olive color.
For the first time, items made of amethyst gold were discovered back in 1931 during archaeological excavations in Egypt. They were found in the graves of Tutankhamun. Many scientists have worked on the secret of obtaining such gold. However, only the American physicist Robert Wood was able to unravel the secret. The alloy consisted of aluminum and master alloy, but was very fragile. For this reason, it was not used to create jewelry.
Several decades later, the work was resumed. Patented purple alloy recipe scientist from Singapore Lo Peng Cham. He has been working on his invention for over 30 years. When the purple alloy hit the markets, it made a splash all over the world. The developments were bought out by the well-known company Aspial, which became the main producer of amethyst gold. The fineness of a Singaporean alloy depends on the amount of precious metal in it.
So, on the products you can find both 750 and 800 samples.
You can get purple gold in another way, which was used by the scientists of the Russian Academy of Sciences. Thanks to the applied nanotechnology, the alloy turned out to be of higher quality and stronger. To create it, microparticles of gold and aluminum were used. In addition, Egyptian scientists also obtained purple-colored metal using a laser.
Properties
TO merits this material should be attributed to the unusual beauty as well as exclusivity. Like any gold items, purple gold items are completely harmless to the human body. Moreover, they do not cause allergic reactions. This makes all items made from purple alloy very popular. As for the shortcomings, there are many more.

- In addition, purple gold requires very delicate handling and regular cleaning.
Application
Usually amethyst or purple gold is used for the production of jewelry... However, in some cases it can be found in microelectronics. But since this material is very fragile, the boards quickly deteriorate.
Sometimes a violet alloy is found at the soldering points of contacts made of aluminum and gold.
As for jewelry production, then amethyst gold is most often used as inserts instead of precious stones... The main part of the product is white or yellow gold. If the jewelry is made only of purple alloy, then it must necessarily have a frame made of a more durable metal.
Sometimes amethyst gold is used to inlay various works of art. It can be paintings, crystal objects, and even sculptures.
Criterias of choice
When making a purchase of items made of purple gold, you should always remember about it. excessive fragility... Therefore, if jewelry is purchased for daily use, then you should pay attention to more durable materials.

- Do not expose them to aggressive agents that can damage such an alloy.
- For cleaning, it is best to use a slightly damp piece of cloth moistened with a solution of soap and water. In the event that the pollution is very strong, it is worth contacting a specialist.
