Carats vs Percentage Method

The percentage method provides a more accurate scientific approach. When you see gold labeled as 99.9% pure, it directly corresponds to 24 carat gold. Here's a breakdown of the common standards:

• 24 carat (99.9% purity): The benchmark for pure gold used in bullion and high-grade applications
• 22 carat (91.7% purity): Popular in jewelry manufacturing, offering durability while maintaining high gold content
• 18 carat (75% purity): Standard for fine jewelry, balancing purity with strength
• 14 carat (58.3% purity): Common in everyday jewelry pieces

International Standards for Commercial Refined Gold

Commercial refined gold follows strict international standards. The London Bullion Market Association (LBMA) requires a minimum of 99.5% purity for gold bars to receive their Good Delivery certification. Most refineries producing investment-grade gold aim for the 99.99% (four nines) standard, which represents the highest level of commercial refining capabilities. This level of purity ensures that the gold meets requirements for industrial applications, investment purposes, and international trade standards.
