## Understanding the International Gold Standard 585
The international gold standard 585 is a measure of the purity of gold alloys. It indicates that an alloy contains 58.5% pure gold and 41.5% of other metals, typically copper or silver.
Composition:
* 58.5% Pure Gold
* 41.5% Other Metals (usually copper or silver)
Characteristics:
* Color: Yellowish gold
* Hardness: Relatively soft and pliable
* Ductility: Easily worked and shaped
* Corrosion Resistance: Resistant to tarnishing
Uses:
Gold alloys with a purity of 585 are commonly used in jewelry, particularly in settings for diamonds and gemstones. They offer a good balance of strength, durability, and affordability.
Comparison to Other Gold Standards:
The international gold standard 585 is less pure than some other commonly used gold standards, such as:
* 9 Karat (37.5%): Less pure and more affordable
* 14 Karat (58.3%): Slightly less pure
* 18 Karat (75%): More pure and slightly softer
* 22 Karat (91.6%): Very pure and soft
* 24 Karat (100%): Pure gold, but too soft for practical use
Advantages of 585 Gold:
* Affordability: Less expensive than higher purity gold
* Strength and Durability: Contains stronger metals like copper to enhance durability
* Versatile: Can be used in a wide range of jewelry designs
* Appearance: Retains a warm, golden color
Disadvantages of 585 Gold:
* Lower Purity: Contains a significant amount of other metals
* Potential for Allergic Reactions: Some individuals may be allergic to the metals present in 585 gold
Conclusion:
The international gold standard 585 is a popular choice for jewelry due to its good balance of purity, durability, and affordability. It is commonly used in settings for diamonds and gemstones, providing a secure and attractive foundation for precious stones.
