Gold is an extraordinary precious metal with a long history. It has the nickname “the King of Metals”.
This material is widely used for jewelry. But also for space travel, dentistry and electronic components.
Approximately 80% of our gold on earth is used for jewelry. That is quite a lot!
This material is connected to the energy of our sun. It’s a very good conductor of energies and high frequencies. It opens the crown chakra and helps you gain wisdom from the universe and your higher self.
It’s also a good energetic protector. For this reason talismans, amulets and protective symbols are often made of this remarkable metal.
Ancient Egyptian priestesses used this pure material to channel healing energies. But coins and the “death masks” of the pharaohs are also made of it. Not surprisingly, this is a popular material. Alchemists, for example, were looking for years for the Philosophers Stone.
With this stone they could convert any material into gold.
Gold itself is a heavy but soft metal that does not corrode. In its pure form it’s so soft that it is almost malleable.
For this reason it is alloyed with other metals to make it harder. The amount of gold in the alloy is expressed in karats. The most common is 14K, 18K and 22K.
With 3D printing it is only possible to get 14K and 18K.
Carat represents a unit of mass (such as gram, kilogram, etc.). This carat is mainly used for gemstones.
1 Carat equals 0.2 grams and 1 gram equals 5 carats.
The other Karat represents a content with a ratio. This Karat is mainly used for alloys of precious metals. The contents are divided into 24 parts. 24 Karat means that 24/24 part is pure gold, in this case 100%. 18K means that 18/24 part is pure gold, so 75% gold and 25% other metals.
There are many different shades of gold. Such as white-, yellow- and rose gold. These colors are the result of the different metals used in the alloy. As explained above, other metals are often added to the alloy to make it harder. Otherwise it is too soft and almost malleable.
The most commonly used additive metals are silver, copper, zinc and sometimes nickel or palladium.
Silver, zinc, nickel and palladium are naturally white metals. Copper, for instance, is naturally reddish. Depending on the ratio of the alloy, the final metal gets its specific color.
For example, 14K yellow gold contains copper and silver (usually a little more copper with a little zinc) to give it its specific yellow color.
14K rose gold, for example, contains a lot more copper with a very small amount of silver and zinc, so you get a much warmer color.
14K white gold, for example, contains much more silver than copper with zinc and nickel (or palladium), which gives it a much whiter color.
The exact proportions of the alloy depends on the supplier or goldsmith. But the percentage is fixed.
