Understanding gold purity is essential for anyone buying or selling gold jewelry, coins, or bars. This comprehensive guide explains the different karat systems and how to calculate the actual gold content in your precious metal items.
Gold purity is measured in karats (K) or fineness. Pure gold is 24 karats, but most jewelry contains alloys for durability. Here's what you need to know:
24K Gold (99.9% pure): The purest form of gold, soft and malleable
22K Gold (91.7% pure): Common in jewelry, good balance of purity and durability
18K Gold (75% pure): Popular for fine jewelry, more durable than higher karat gold
14K Gold (58.3% pure): Affordable option, very durable for everyday wear
To calculate gold value, multiply the weight by purity percentage and current gold price per gram.
