If you are wearing your charm or ring all the time, the 22k gold lustre will eventually wear away, especially if you decide to wear it whilst bathing, or in a way in which it rubs against other jewellery. If you wish to have the gold lustre re-applied to your piece, you can purchase this service here. You must pay to ship the piece safely back to me. The £5.00 charge is for the lustre and return shipping to you. Once you purchase this service I will send you an email with my postal address. Ship the item to me, let me know roughly when to expect it, and once the lustre is put back on I will ship it back out to you.
