If you need to calculate the Zakat on your Jewellery, simply workout 2.5% of your gold value, this can be done by using the gold price on the day.
For example, assuming you have 150 grams of gold jewellery in 22ct and the 22ct gold price is £ 44 per gram (£440 for 10 grams).
(150 x 41) / 100 x 2.5 = £ 153.75 Zakat
