We have a huge stock of certified natural and lab grown diamonds sourced directly from the industry's largest trade suppliers. There may be a few days delay in shipping these orders while we get them from our suppliers and check them over for you before shipping. We apply a small margin for our time to do this. Currently the diamonds shown here are not returnable. All videos are of the actual diamond you will receive. Please contact us for a quote to set these into a bespoke piece.
