10K vs 14K vs 18K vs 22K vs 24K Gold Value
Karat is the biggest reason two items with the same weight can have very different gold values.
What karat means
Karat tells you how much fine gold is in an alloy. 24K is treated as pure gold, 18K is 75%, 14K is about 58.3%, and 10K is about 41.7%. This is why two rings with the same weight can produce different estimates. The higher-karat ring contains more fine gold.
Why jewelry uses lower karat
Pure gold is soft, so jewelry is often mixed with other metals for durability, color, and price. That does not make it fake; it means the fine-gold percentage is lower. The calculator focuses on gold content, not brand, design, gemstones, collectability, or resale premium.
How to compare items
When comparing items, look at both weight and karat. A heavy 10K chain can contain more fine gold than a tiny 18K pendant. Use multiple-item mode for mixed jewelry so each piece keeps its correct purity.
Key points
Karat measures fine-gold content out of 24 parts. 24K has the highest melt value at the same weight. Lower karat can still be valuable, especially at higher weights.
