We all associate gold with a soft, malleable, highly conductive yellow metal with unique properties and an impressive list of advantages. But gold experts know that this precious metal can sparkle not only in yellow shades.
Check the list of gold colors existing on the planet. Spoiler: some of them you’ll face for the first time…
What impacts the gold color?
In nature, gold has a rich yellow color. As for jewelry production, it has never been used in a pure form, as it’s plastic, which makes the metal unstable to deformation. However, this problem can be solved by using some compounding material for the gold alloy. Usually, it is metals found in nature: copper, palladium, and others. Impurities of other components are called ligatures, which determine gold color.
To find out how much gold is contained in an alloy, check its purity. It demonstrates how much precious metal is contained in a kilogram of alloy. For example, 585 purity means that a kilogram of alloy contains at least 585 grams of gold, while 415 grams are impurities, that is, ligature.

Yellow gold is characterized by 750 rate purity. It’s a high-quality metal, which is used in elite jewelry making, as the alloy has a rich yellow tint due to a large amount of pure gold in the ligature (at least 750 grams per kilogram). The ligature in such an alloy is represented by copper and silver, taken in equal proportions. Jewelry made of yellow aurum looks expensive, but requires careful handling – the predominance of pure gold in the alloy makes it fragile and prone to deformation.
Jewelers are absolutely in love with white gold. It’s perfectly combined with gems and enhances the splendor of diamonds. White gold is made of traditional gold with palladium and platinum, nickel, and silver.
Most often, white gold is extremely durable and has a 585 or 750 purity rate.
How to distinguish between white gold and silver? It may appear that the color of these alloys is the same. Indeed, they are very similar. However, if you look closely, you’ll notice that silver is characterized by a cold steel undertone, while gold jewelry is white.
Moreover, metals can be distinguished by sound. To do this, toss two products so that they land on a table or other hard surface and listen. Gold has a more sonorous sound, while silver has a softer sound. The thing is that metals have different hardness.
This is an alloy with the lowest purity. The red tint is achieved by adding a large amount of copper (approximately 600 grams per kilogram). An insignificant part of the ligature (25 grams) consists of silver.
For a decorative effect, jewelers sometimes add palladium to give it a reddish shade.
Pink gold looks very chic and stylish. Jewelry designers who create wedding collections adore this metal. Today, it is rose gold that sets the trend in fashion.
A sweet pink hue is achieved thanks to the mix of gold with Argentum and copper.
Brown or “chocolate” gold appeared thanks to the founder of the de Grisogono brand, who often experiments with the jewelry. The jeweler doesn’t disclose his technology for obtaining such a shade. But experts insist that this is due to nickel, manganese, iron, and copper.
Black tinted gold makes the piece of jewelry truly noble and a little mysterious. The process of its making requires a lot of effort, time, and funds. The easiest way to get it is by alloying pure gold with chromium and cobalt. Then the resulting material is oxidized and scorched at high temperatures.
Green gold is an incredibly beautiful metal, but not all varieties are safe for health. The classic version is created from gold, copper, and silver. The more silver it contains, the more delicate olive color the finished product acquires.
However, such jewelry is extremely fragile and can cause a severe allergic reaction. So green gold is often used by craftsmen to create masterpieces for professional exhibitions.
There are also purple, azure, gray, and navy blue shades of gold, however, they are almost never used in jewelry making. Such metals are very fragile and not wear-resistant.
Not only jewelry is made of gold. “Edible” metal is used even in the food industry and cooking.
Still, bars and coins are considered to be the most flawless gold (you can see examples on the Pacific Precious Metals website) – they are the most expensive, stable, and valuable. The purity of such gold bars is the highest possible – 999, which means that there is only one “non-gold” particle for every 1000 gold ones. It is this gold that banks, major companies, and investors use to preserve and increase their capital.
