Each country has its own duty on mounted rings based on the value of the centre stone and semi-mount. Our ring prices include the local duties on the semi-mount only. Please factor these duties into your diamond markups.
For example, the US has a 6.8% duty on the value of the ring. The price of the semi-mount will include the duty on the gems and metal in the semi-mount but you will have to pay a 6.8% duty on the value of the diamond separately.
