Platinum jewelry is usually 950 platinum (95% pure) or 900 platinum (90%), stamped PLAT, PT950, or PT900. It is denser and rarer than gold, and is also found in lab and industrial scrap.
This calculator converts the weight to troy ounces and applies the live platinum spot price. Choose your purity below - 950 is the most common for rings and fine jewelry.
