How the per-gram price is calculated
World gold markets quote one price: US dollars per troy ounce. A troy ounce is 31.1035 grams, so the price per gram is simply the spot price divided by 31.1035. There is no separate gram market and no separate gram price — every dealer, refiner and jeweler starts from the same ounce quote and does the same division. If a buyer quotes you a per-gram price well below this page, the gap is their margin, not a different market rate.
