Sure, for something like a pendant if I knew what I was looking at and the price was right.
For example, if I knew it was in the colorless range, I couldn''t find the inclusions myself with a loupe and/or they were hidden, and I had an idealscope to check the light leakage.
Otherwise, no I wouldn''t and especially not for an important piece. Too many unknowns, especially cut which is the most important one of all!
Yes, and it was a mistake as far as QUALITY of CUT. The price was okay, the diamonds were 1 carats, completely eye clean but when compared to an ideal diamond.... you could tell a difference.
maybe if it was an antique piece, but I would have it independently appraised and make sure the vendor has a good return policy. I''d never do it on ebay!
Yes I would, if I trusted the jeweler. My 3 stone has 3 gorgeous stones, complete with viewable arrows, and they are not certified. That being said, the jeweler who got the stones for us and put it all together is a very good personal friend who has been in the business for years. I let him do all the picking, after I told him the specs I wanted, and my DH and I are stunned daily at how gorgeous these stones are!
I would for smaller items, like smaller ctw earrings or a pendant. But I would only do it from a trustworthy jeweler that I had built a relationship with.
Also, I would buy an antique diamond or diamond ring but I would definitely want to get it appraised after I bought it.
Yes I would, if it is an antique diamond through a jeweler that I trust. If I were going to by a modern cut diamond I would probably just get something that was certed, since there are so many out there.
