We are so sorry to hear that you haven't yet received your necklace. Do get in touch with us at enquiries@mantrajewellery.co.uk so we can look into it for you. The Royal Mail has struggled in some areas with the volume of mail over the Christmas period, combined with Coronavirus absences, so it may simply have been delayed in the post slightly. They were asking us to allow up to 10 working days for delivery before Christmas.
