What Does 585 Mean on Jewelry?
Anyone who has taken a close look at a piece of fine jewelry has likely noticed a minuscule stamp somewhere on it. These stamps vary and can carry a plethora of meanings. But one stamp in particular often has many scratching their head. What does 585 mean on jewelry? Read on to learn about what 585 means, whether it’s real gold, how it compares to other gold types, and whether it’s worth selling.
In a nutshell
A 585 marking indicates 58.5% pure gold, equivalent to 14K gold. Because more than half of the piece is real gold, it retains inherent value and can be sold based on its gold content, regardless of style or age.
What Is 585 Gold?

To put it simply, 585 on jewelry means it is 58.5% pure gold. These stamps, called hallmarks, allow jewelers to identify and provide information about the piece. This particular hallmark denotes fineness, similar to karats but with slight differences.
Fineness measures gold purity in parts of 1000. So 585 means the gold used contains 585 parts per 1000 of pure gold. The karat system uses parts per 24, so pure gold is 24K. Each karat marking means there are that many parts of pure gold per 24 total parts. For example, 14K gold means the piece contains 14 parts of pure gold per 24.

For high-value items, sellers may be able to fetch a higher price on peer-to-peer platforms like eBay or Poshmark. Pieces made by notable designers or with a vintage appeal may do well on high-end auction sites or on consignment platforms such as The RealReal. While it may be possible to extract more value from a piece this way, it does take much longer than some other selling options. Fees also eat into profits, cutting into the seller’s take-home pay.
When selecting a method of sale, sellers should always compare options. It’s wise to obtain a couple of offers before making a decision. When selecting a buyer, consider these tips to help choose a reputable option:
- Look for transparent pricing. A reputable buyer should clearly explain how offers are calculated and use the current market price of gold.
- Be cautious of pressure tactics. Reputable buyers allow sellers time to review offers and will not rush them into making a decision.
- Check reviews and business history. Businesses should have online reviews, show longevity, and display clear contact information. These establish that the company is active and reliable.
- Ask about fees and deductions up front. Legitimate buyers will not shy away from payout discussions.
- Get offers in writing. A written quote helps prevent misunderstandings and provides proof of the terms offered. Offers should be detailed and break down each piece in the lot individually.
- When selling online, use insured shipping. A reputable online gold buyer will always offer free shipping, insurance, and tracking for items in transit.
By following these tips, one can ensure they are dealing with a reputable service.
