1Purity (karat): 18k gold is 75% pure gold and 9k is 37.5%. The higher the karat, the more it is worth per gram.
2Weight in grams: we multiply the weight by the per-gram value for your karat.
3Official price: we use the LBMA gold reference price, updated through the day.
4Final appraisal: your definitive offer is calculated after an XRF laboratory analysis that measures each item's real purity.
