Gold grade measures the amount of gold within ore before it's processed, while gold purity refers to the percentage of gold in the final, refined product. Gold purity is either measured in fineness (the number of parts gold per 1,000 parts) or gold karats, where 24 karat gold is deemed pure.

Calaverite is a telluride mineral that's really special because it's packed with gold. It's not just a rock with a little bit of gold; it has a lot of it, making it pretty unique. In calaverite, gold isn't just a tiny part – it makes up about 42% of the mineral. This means that calaverite is almost half made of pure gold.
