You have 30 days, from the date you receive the diamond to inform us that you would like to return it. If you desire to return it, you must inform us first and we will provide you with an RMA number. Upon receipt and verification that everything is in order, you will receive a complete refund of the cost of the stone. We do not provide refunds of custom mountings, however, we will accept custom mountings back and re-work any unacceptable element of the mounting. If the diamond jewelry has been used or worn the return will be void.
