Our friends at the Perth Mint Bullion Blog explain how purity, fineness and karats fit together when talking about precious metals. I learned from the article that Good Delivery gold bars are 99.5% pure (995 fine) because it takes additional processes and expense to refine gold the extra 0.4% to reach 99.9% (999 fine).
