My fiancee has just purchased a diamond and we would like to have a tension setting for it (we have one picked out at titanium-rings.com). This website wants us to send them the diamond so they can mount it and construct the ring, which is understandable. Before we send it to them (I think they're in Montreal), we want to know if they're reputable. I can't find them anywhere with the BBB or AGS...does anyone know where else I can look to check credentials? Or has anyone worked with this website before? Also, do you think it woud be possible to get the ring with a CZ in it and have a local jeweler set the diamond? I worry that a local jeweler won't have the experience and knowledge to set it correctly- we live in Knoxville, TN. Thanks for the advice.
