Rent Your Rocks is quite possibly the best idea we've heard in ages. Rather than actually selling its fabulous range of stunning fine jewellery, this innovative company offers you the opportunity to rent it by the week, allowing you to wear pieces that you might otherwise never be able to afford. Some of the pieces are worth thousands of pounds, yet are available to rent for less than 10% of the price. Just choose the piece you like, decide how long you want it for and it will be delivered to your door by post. Once you've finished with it all you have to do is send it back in the pre-addressed envelope, then admire all the photos of yourself in your gorgeous bridal bling!
