What Does 585 Mean on Jewelry?

Have you ever flipped over a piece of jewelry and noticed tiny numbers stamped inside?
These markings aren’t random—they’re hallmarks that tell you exactly what your jewelry is made of.
Understanding these stamps is crucial whether you’re buying, selling, or simply curious about what you already own. They reveal the metal’s purity, authenticity, and value. One of the most common marks you’ll encounter is “585,” and knowing what it means can save you from overpaying or being misled.
What Does 585 Mean on Jewelry?
The number 585 stamped on jewelry indicates that the piece contains 58.5% pure gold. The remaining 41.5% consists of other metals like copper, silver, zinc, or nickel.
This marking is the European way of denoting what Americans call 14-karat (14K) gold. Both systems describe the exact same purity—just expressed differently. While the U.S. uses the karat system, many other countries prefer the more precise decimal notation.
The History Behind the 585 Gold Mark
Gold hallmarking dates back centuries, originally developed to protect consumers from fraud and ensure quality standards. Different regions adopted different marking systems based on their measurement preferences.
European countries, Russia, and many Asian nations gravitated toward the numeric system because it directly states the percentage of gold content. This eliminates confusion and makes verification straightforward.
The 585 mark became standardized across these regions as trade expanded globally. It remains the preferred marking in most of the world outside North America, where the karat system dominates.
How 585 Gold Compares to Other Gold Purities
24K Gold (999)
Pure gold measures 99.9% purity and carries a 999 hallmark. It has a rich, deep yellow color and maximum softness.
However, this extreme softness makes it impractical for most jewelry. It scratches easily, bends out of shape, and doesn’t hold gemstones securely. You’ll mainly find 24K gold in investment bars and coins rather than wearable pieces.
22K Gold (916)
With 91.6% gold content, 22K gold is immensely popular in India, the Middle East, and parts of Southeast Asia. It offers a warm, vibrant yellow hue close to pure gold.
While more durable than 24K, it’s still relatively soft. It works well for traditional jewelry that’s worn occasionally but may not withstand the rigors of daily use in active lifestyles.
18K Gold (750)
Containing 75% pure gold, 18K gold strikes a balance between luxury and practicality. The 750 hallmark indicates higher gold content than 585.
This purity level offers richer color, higher prestige, and greater value. However, it’s softer than 14K gold and comes with a notably higher price tag.
14K Gold (585)
The 585 marking represents the sweet spot for most jewelry buyers. With 58.5% gold content, it’s durable enough for rings, bracelets, and other pieces that face daily wear.
It maintains a beautiful golden appearance while resisting scratches and dents better than higher purities. The price point makes quality gold jewelry accessible without sacrificing longevity.
10K Gold (417)
At 41.7% gold content, 10K gold is the minimum purity that can legally be called “gold” in the United States. It’s the most durable option but has a paler color.
This budget-friendly choice works well for those who want real gold jewelry at the lowest price point. However, some people find the color less appealing, and it has lower resale value.
Is 585 Gold Real Gold?
Absolutely—585 gold is genuine gold, not plated or fake. The presence of other metals doesn’t make it less “real.”
Pure gold is too soft for practical jewelry use. Alloying it with other metals creates a material that’s strong enough to hold its shape, secure settings for gemstones, and withstand years of wear.
The 585/14K composition has been refined over centuries to achieve optimal performance. You get authentic gold that actually functions as durable jewelry rather than a delicate ornament.
Colors of 585 Gold
Yellow Gold 585
Traditional yellow gold 585 typically contains gold alloyed with silver and copper in specific ratios. This creates the classic warm, golden color most people associate with gold jewelry.
The exact shade varies slightly based on the precise alloy mix, but it maintains that timeless golden glow. Yellow gold 585 complements most skin tones and never goes out of style.
White Gold 585
White gold achieves its silvery appearance through alloying gold with white metals like palladium, nickel, or manganese. Despite the name, the natural color is slightly grayish.
Most white gold jewelry receives a rhodium plating to enhance its bright, white finish. This plating may wear off over time and require re-plating every few years, depending on wear.
Rose Gold 585
The romantic pinkish hue of rose gold comes from adding copper to the gold alloy. The more copper present, the redder the tone.
Rose gold has surged in popularity over recent years for its vintage-inspired, feminine aesthetic. The copper content also makes it one of the most durable gold color options.
Advantages of 585 (14K) Gold
Durability stands out as the primary benefit of 585 gold. The alloy mixture creates jewelry that withstands daily activities without constant worry about damage.
The price point makes quality gold jewelry accessible to more buyers. You’re not paying for the maximum gold content you’ll find in 18K or 22K pieces.
Resistance to scratching and denting means your jewelry maintains its appearance longer. While not completely scratch-proof, 585 gold holds up remarkably well.
Wide availability makes finding and replacing 585 gold pieces easy. Most jewelers stock extensive selections in this purity, giving you plenty of options.
How to Identify 585 Gold
Look for the “585” stamp on the inside of rings, the clasp area of necklaces and bracelets, or the back of earring posts and pendants. You may need a jeweler’s loupe to spot smaller markings.
Additional stamps might appear alongside the 585 mark. These could include the manufacturer’s mark, a country of origin stamp, or other quality indicators.
Be cautious of pieces with no markings, poorly stamped numbers, or marks that wear off easily. Genuine hallmarks are clearly stamped and permanent. If you’re uncertain, have a jeweler test the piece with professional equipment.
585 Gold Value: How Much Is It Worth?
The value of 585 gold jewelry depends on several factors beyond just the gold content. Current market gold prices form the base value—you can calculate roughly 58.5% of the current gold price per gram.
Craftsmanship significantly impacts price. Intricate designs, hand-finishing, and artistic merit add substantial value beyond the raw metal worth.
Brand names command premium prices. Designer pieces from established jewelry houses cost more than comparable unbranded items, though both contain the same gold purity.
Resale value typically runs 50-70% of retail for 585 gold, depending on condition and buyer. Pawn shops and gold buyers usually offer less than private sales or consignment through jewelers.
How to Care for 585 Gold Jewelry
Regular cleaning keeps your 585 gold jewelry looking its best. Mix mild dish soap with warm water, gently scrub with a soft toothbrush, and rinse thoroughly.
Store pieces separately in a fabric-lined jewelry box to prevent scratching. Remove jewelry before swimming, showering, or applying lotions and perfumes.
Professional cleaning and inspection every six months helps catch loose stones or worn prongs before you lose anything. Jewelers can also re-polish pieces that have developed surface scratches.
Avoid harsh chemicals like chlorine and bleach, which can damage both the gold and any gemstone settings. Remove rings before working with cleaning products or doing heavy manual work.
FAQs
Yes, 585 gold represents excellent quality for everyday jewelry. It offers the durability needed for pieces you wear regularly while maintaining authentic gold content and appearance.
Exactly the same. The 585 marking and 14K designation both indicate 58.5% pure gold content—just different marking systems used in different regions.
Pure gold doesn’t tarnish, and 585 gold is highly resistant to tarnishing. You might notice some dulling over time from oils and dirt buildup, but this cleans off easily and isn’t true tarnish.
While 585 gold itself won’t be damaged by water, it’s best to remove jewelry before showering. Soap residue can build up, and you risk damage to gemstone settings or losing pieces down the drain.
Conclusion
The 585 mark on your jewelry confirms you own genuine 14-karat gold with 58.5% pure gold content. This purity level has become the global standard for quality jewelry that balances beauty, durability, and value.
Whether you’re shopping for new pieces or evaluating what you already own, understanding hallmarks empowers you to make informed decisions. Look for that 585 stamp, and you’ll know you’re getting real gold that’s built to last through years of wear and enjoyment.
