Hi Gurjeet,
It is a fixed fee of £30.00 no matter where in the world it is heading.
It is high because jewellery is a high value item that needs to be insured when being sent. The cost of sending an insured item of jewellery,through FEDEX to New Zealand is greater than the £30.00 we charge.
We used to send the jewellery another cheaper way but we had problems with lost parcels etc, so we believe that this is the best soloution for us and our customers.
