What are the different variations of gold?

There are many types of gold, including white gold, yellow gold, pure gold, and, of course, 14-karat gold, 18-karat gold, 24-karat gold, and so forth and so forth. We are probably all familiar with these types of gold. What sets these various types of gold apart from one another?

We thought that it might be helpful to provide a brief explanation of each of these different kinds of gold, so here it is. In this way, if you are interested in purchasing gold jewelry, you will be able to go to the best Jewelers with the knowledge that will assist you in making the choice that is most suitable for you. You can easily sell gold in Miami FL, online easily when you have enough knowledge. 

Gold in a rose hue

In some circles, pink or red gold is referred to as rose gold. You can make it by combining gold in its purest form with copper, which also gives it its characteristic red color. The ratio of gold to copper that you use to create rose gold yields shades of color that are very distinctive from one another. The final color will be darker if there is a greater quantity of copper and if the percentage of copper in the mixture is higher.

The ratio of gold to copper that is typically used in jewelry is 75%:25%. It is not possible to make rose or white gold that is completely pure. The optimal strategy is to combine it with various other components in order to achieve the ideal tone that is tailored to your preferences.

Because it is colored with copper, which is a relatively inexpensive metal, it is also the type of gold that has the lowest price. Because of the presence of copper, it is considerably more durable than white or yellow gold.

Green gold

Electrum is another name for green gold, also recognized as electrum. In most cases, it is combined with gold, silver, and sometimes even copper in some instances. The bluish-green hue that can be seen on this gold alloy is due to the presence of silver.

Around the year 860 BC, ancient people began using green gold. It was referred to as electrum at the time. The color of this naturally occurring alloy of gold and silver is closer to a greenish-yellow than it is to green.

Alternatively, the green color can be accomplished by incorporating cadmium into a gold alloy. However, due to the fact that this practice is extremely hazardous, it is not very common. In order to obtain an alloy with a dark green color, 4% cadmium, 6% copper, 15% silver, and 75% gold are required.

Gold that has been electroplated

Electroplating is a method utilized in modern gold layering that involves charging the base metal through the use of electrical currents. After that, it is immersed in a solution of positively charged ions, which also are drawn to the base metal’s negative charge because of the solution’s positive charge. A layer of gold is produced as a result of their attachment to the base metal. Electroplating enables the rapid production of jewelry with gold plating at such a cost that is comparatively low. In addition, the method produces a layer of extremely long-lasting gold alloy.

Gold in black form 

Some other type of gold that is commonly used in jewelry is called black gold. There are a few different routes that can be taken to produce black gold. One method is to use compounds based on sulfur and oxygen to bring about oxidation. The controlled oxidation of gold that also contains chromium or cobalt (for example, 75% gold and 25% cobalt) is another method. By treating copper-rich alloys with potassium sulfide, one can produce a spectrum of colors on the surface of the alloy, ranging from brown to black.

Gold in Gray

It is the result that is produced when palladium and gold are combined. This type of metal is an alternative that is significantly less expensive. It is produced by combining iron, silver, copper, and manganese in specific proportions and then heating the resulting mixture. The proportions of gold, copper and iron that are most frequently utilized in the production of the alloy are 75% gold, 8% copper, and 17% iron. This is the most popular type that people sell gold in Miami, FL. 

Gold in Blue

Pure gold must be combined with either indium or gallium in order to produce blue gold. Alloys made of gold and indium have a composition of 46% gold and 54% indium, which also leads to the formation of an intermetallic compound that has a deep blue hue.

In alloys of gold and gallium, the gold takes on a color that is slightly bluish. By alloying gold with rhodium and ruthenium, one can achieve a rich blue color that is between 20 and 23 karats.

Both price and longevity are impacted by the amount of gold present in terms of karat. Compare, for instance, a ring made of 10 karat gold to one made of 14 karat gold. The 10k gold ring has already been mixed with much more alloys than a standard 10k ring, which tends to make it more durable for day-to-day wear but results in the ring having a lower gold content overall. When compared to 10k gold, a 14k gold ring would have much more gold, but it would also be subject to more daily wear. However, it would be worth more.
