Dear Sarah,
We do have this ring in stock in a size U,I would advise for you to take the ring we have in a size U, if then you are 100% sure about it, you can return it and we will make it a size W, at which point it would become non refundable.
We aim to send all jewellery within 24 hours of receipt of the order and whenever possible we will send your order in the next available mail out (Monday - Friday).
Thank you for your enquiry
