I actually had the stone set at a local jeweler. They indicated there was no way they could have matched that price for a stone that size and quality. It would have been probably about 15-20 percent smaller all other things being equal. Decide what your price range is and what stone size will be appropriate, and then check a local dealer. Then go online and see how close it is. It will also depend on the shape of the stone what might be available locally.
