My grandmother has passed down some heirlooms. The diamonds are really beautiful and great quality but the mountings are very antique-looking and complicated, where she admits that it is hard to wear it regularly. She doesn't ban the heirlooms to be sold but I don't really want to sell it. I just want to change the mounting but my paranoia will not let me to give it to some jeweler to take care of it. In my country, there are jewelers who would measure the diamonds and make the mounting and a few weeks later would implant the diamonds in front of the owner. This is to make sure that the diamonds are not switched. So my question is this: If you were in my situation would you a. sell the heirlooms and get something else (still diamonds, just not sure where from: winston, debeers, h.on.fire, bvlgari, etc, etc) b. change the mounting If you pic b, where is the place to do it safely? Thanks.
