Lunn's Portfolio of Fine Diamonds offer a free ring sizing service. We will ask you for the ring size when you place your order. If you know it, we will endeavour to have your ring sized prior to despatch. This may add a few days on to the despatch of the ring, but we will call you or e-mail all of the relevant details when you place your order. A free ring sizer is included with every order to facilitate you in finalising your ring size. Please return the ring to us by recorded and insured mail and we will arrange to have the ring sized and returned to you, again by FREEPOST. In the event that the ring cannot be sized to the correct size, we may need to manufacture a new ring for you. It may be necessary to source a new diamond to ensure we can fulfil the order and meet your requirements. We will keep you informed if this is the case and update you on a delivery date. If this does not fit with your plans, a refund or exchange of the ring can be requested, as set out in the terms of our Returns Policy.
