Should you be unable to clean your Hold upon Heart jewellery yourself, then you can return it to us for a professional clean and re-polish. We are only able to offer this service on jewellery we have made. Please ensure you contact us for the studio address before sending your jewellery. We advise you use royal mail's special delivery service which offers insurance against loss in the post. Jewellery will be returned to you by special delivery, which is included in the price.
