Pure gold is too soft as a material for jewelry production. Gold alloys are used instead. An alloy is a mixture of different metals that are melted together.
585 gold is the most commonly used gold alloy for jewelry worldwide. The fineness of 585‰ thousand parts corresponds to the value of 14 carats.
A piece of jewelry with 14 carat therefore consists of 58.5% pure gold, the rest consists of other precious metals, such as copper or silver, which are added to make the gold more dimensionally stable and scratch-resistant.
Check fineness: 585 gold = 14 carat
The fineness of gold jewelry is usually embossed in the form of a hallmark. Both the carat number, such as "14 kt." or more rarely "14k" or "14c", and the fineness in parts per thousand, such as "585", can be hallmarked. Such a hallmark can be found on the inside of rings and usually on the clasp of chains or pendants.
In order to check the correctness of hallmarks, the acid test, also known as a line test, is usually used when buying gold.
The piece of gold to be tested is rubbed on a test stone, a slate, in such a way that a clear line remains. Various test acids are then applied to this test mark one after the other. Each alloy has its own test acid, which consists of a mixture of hydrochloric acid and nitric acid (aqua regia).
If the abrasion on the test stone becomes twisted or discolored, the alloy is below the tested fineness; if the line remains unchanged under the influence of acid, the gold content corresponds to the respective carat activity.

Our prices for 585 gold jewelry
If you want to sell old gold made of colored gold alloys, you will generally receive the same price for 14 carat white gold or red gold as for 14 carat yellow gold. The 585 gold price is identical for all these alloys.
The relevant factor when buying gold is the proportion of gold it contains - the fineness - and this is the same for 14 carat yellow gold as for 14 carat red or white gold, namely 58.5%. The difference in color is only due to the mixture of different metals (alloy).
