How this calculator works
The calculator starts from the live 24K gold price per troy ounce, converted to EUR 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.
Across the eurozone, jewellery standards vary by country: 18K (750) dominates fine jewellery in France, Italy and Spain, while 14K (585) is common in Germany and central Europe. 22K and 24K jewellery is rarer and mostly found in communities with South Asian or Middle Eastern gifting traditions.
