If you pick up the jewel in Belgium, you will need to advance the VAT.
You can claim the VAT back by having the invoice stamped at customs before you leave the European Union. You then need to send the original copy of this stamped invoice back to us at Hoveniersstraat 30, 2018 Antwerp, Belgium. As soon as we receive this document, we will refund the VAT. You can find more information here.
