How this calculator works
The calculator starts from the live 24K gold price per troy ounce, converted to AED at the current exchange rate. Your weight is converted to grams (1 troy ounce = 31.1034768 g, 1 tola = 11.6638038 g), and the value is adjusted for purity — the multiplier is simply the karat divided by 24, so 22K/916 gold uses 22 ÷ 24 ≈ 0.9167. The formula: value = grams × pure gram price × purity, plus any premium and minus any discount you enter.
In the UAE, 22K and 21K gold dominate jewellery sales, with 18K used for lighter designer pieces. Dubai's Gold Souk and malls display the official daily rate for each karat, published in dirhams per gram, and negotiate making charges on top.
