Karats, making charges and VAT
Karat is the share of pure gold out of 24: 24k is about 99.9%, 22k 91.6%, 21k 87.5% and 18k 75%. So a gram's price is the 24k price × karat ÷ 24. 21k is the most common for jewellery in Saudi Arabia.
Shops add a making charge per gram when selling and usually buy back at the raw price. Jewellery carries 15% VAT in Saudi Arabia, while investment gold of 99% purity or more is generally zero-rated. Prices move daily, so enter today's rate.
