If a gold product bears the hallmark '585', then your gold has been tested and classed as 14 carat or 58.5 per cent pure.
The proportion of other metals can vary, but the 585 designation always indicates a minimum of 58.5% gold content. 585 gold jewelry is also known as 14-karat gold, a standard for gold purity used worldwide. In the United States, 14k gold is the most common type of gold jewelry.
585 gold is labeled as 14 karats and is 58.3 percent pure gold. When a piece includes 585 gold, the rest of the item's ingredients are alloy metals. Some jewelry manufacturers and sellers will use a slightly higher percentage of gold so that they can call it “585” gold.
To summarize, this was all about the 750 mark and 585 marks. We know that 750 marks mean 75% purity which is 18 karat whereas 585 means that it's 58.5% pure gold. If you measure 585 in karat, it's 12 karat gold.
If the piece is stamped, as in 585 (the European stamp for 14k), in most cases, the gold is real and the karat content is accurate. In some instances, the gold is real but the karat content is not accurately stamped. This is termed “under-karating” and violates both state and federal law.
'585' gold is just one of many different types of hallmarks. If a gold product bears the hallmark '585', then your gold has been tested and classed as 14 carat or 58.5 per cent pure. The remaining 41.5 per cent of the item is composed of different metals such as nickel, copper, or in some cases silver.
An ounce of pure gold is worth $1955.34 today, whereas an ounce of 585 gold is worth $1031.55 today.
Technically, it does not tarnish. It changes colors over a period of time. Let us take a look at the quality of white gold, what changes its colors, and how to prevent it. White gold is made from mixing pure yellow with white metals — silver, platinum, and palladium.
For example, 14 divided by 24 is 58.5, so a 14kt gold piece would be 58.5% pure gold and would get stamped as “585.” “Sterling silver” is 92.5% pure silver, so it might be stamped as “925.” Platinum is usually 90% to 95% platinum and 10% to 50% iridium alloy.
Wearing solid gold jewelry, white gold or yellow gold, in the shower will not harm the metal itself, however it can reduce the shine therefore it is not recommended. Showering with gold plated jewelry can eventually cause the gold layer to wear off completely, therefore you should definitely refrain from doing so.
The gold content of an 18K jewelry item is therefore 18/24 or 75% pure gold. According to the European system, 18K gold is marked 750, 14K gold is marked 585, 10K gold is marked 420. 10K gold is the lowest percentage allowed to be marked and sold as Karat Gold Jewelry in the United States.
Here's the quick answer: 750 means 18-karat gold. 585 means 14-karat gold. 417 means 10-karat gold.
333er gold has a fine gold amount of 33.3%. Jewellery made of 333er gold is often mixed with a very high percentage of copper. This jewellery is often recognizable by a slightly reddish gold tone. 585er gold has a fine gold amount of 58.5%.
The 585 jewelry marking means a piece has 58.3 percent gold content. The jewelry mark 585 is not used as often as the 14K jewelry stamp, although the jewelry mark 585 indicates the same thing that jewelry contains 58.5 percent gold and 41.5 percent alloy.
To be considered “platinum,” the metal must contain at least 95% pure platinum. Many jewelers have begun to offer a more affordable alternative, 585 Platinum, containing 58.5% platinum and 41.5% copper and cobalt. Platinum's natural color is silver-white, which can lead to confusion with white gold.

Salt water, chlorine, soaps, detergents, and lotions: All of these will start to wear off the rhodium plating. Rubbing: The more your white gold is being rubbed, the faster it will turn yellow, which is why rings turn yellow quickly.
White Gold Is Not Hypoallergenic
Some of these alloys could easily irritate your skin if you have a sensitivity to those metals. If you know that you have any of these allergies, then you may want to pick platinum for your wedding band, which is a hypoallergenic metal.
14-carat gold has a higher purity and therefore more pure gold colour than 9-carat gold but is much harder and resistant to damage than 18-carat gold due to the addition of alloys.
For the most part, the two metals will be priced equally based on the same presence of pure gold. That means that 14k white gold will be comparable in cost to 14k yellow gold. In some instances, a jeweler may charge slightly more for white gold since it has the addition of rhodium plating.
Thus, the fineness mark is 585 in most 14 carat gold jewellery.
