If I were to buy a pre owned tacori, or just one off ebay would I be able to get an old european diamond set in it fairly simply, or would this be a huge headache? My girlfriend likes some of the tacori rings, but also likes the old european stones. Im not sure yet what route we want to go, but Im checking my options. She knows it would be pre owned and doesnt care fyi. I get the feeling she doesnt want me spending a ton of money. Anyway, any advice would be great. Thanks.
