Short Answer
Complete Explanation
The marking “585” on a piece of metal indicates that the alloy is composed of 58.5% pure gold, with the remaining 41.5% consisting of other metals such as copper, silver, or zinc. This proportion corresponds to 14 karat gold, a common standard in many countries, especially in Europe and parts of Asia. The 585 hallmark is part of an internationally recognized system that allows consumers to verify gold purity. It is typically stamped on jewelry, watch cases, and other decorative items, often alongside other marks that denote the manufacturer, country of origin, or additional alloy specifications.
- Gold content:
58.5% pure gold (14 karats). - Common alloys:
Copper, silver, and zinc are added to improve hardness and color. - Regional usage:
Predominantly used in the European Union, Russia, India, and other markets that follow the millesimal system. - Hallmarking standards:
Often accompanied by other symbols such as the maker’s mark, date letter, and assay office stamp. - Durability:
14K gold is harder than 24K gold, making it suitable for everyday jewelry while retaining a rich gold appearance.
Common Misconceptions
585 means the gold is 585 karats.
The number refers to the millesimal fineness (58.5% gold), which equals 14 karats, not 585 karats.
585 gold is inferior to 750 gold.
While 585 gold has lower purity than 750 (18K) gold, it offers greater hardness and is less prone to scratching, making it suitable for certain jewelry types.
FAQ
What does the 585 stamp tell me about a gold item?
The 585 stamp indicates that the item contains 58.5% pure gold, which is equivalent to 14 karat gold. It confirms the gold content according to the millesimal fineness system.
Is 585 gold suitable for everyday wear?
Yes. Because 14K gold (585) is harder than higher-purity golds like 24K, it resists scratches and dents better, making it a practical choice for rings, bracelets, and other pieces worn daily.
Can 585 gold be re‑hallmarked if it is repaired?
When a 585 gold item is repaired, a new hallmark may be applied if the repair involves adding or removing metal. The new hallmark must reflect the current gold fineness, which should remain 585 if the original alloy composition is unchanged.
