Any one know of lab or other non natural being sold as natural rough diamonds? Bought one 3 years ago and thinking of getting a few more to set in silver, small, 1ct. or so. Thanks

Then, I guess you know all synthetic diamonds will be type II. Type I and type II diamonds can be distinguished by type II’s transparency under short-wave ultraviolet radiation and both types can be definitively separated by infrared spectroscopy or a buddy with an EXA.
Natural diamond xls commercially available for the public are usually a bit ugly.....except for the John Betts specimens. I'd still rather see them in a display case than in jewelry.
There are lots of imitation rough diamonds on the market. However, most are in the diamond fields where small dealers sell them to uneducated buyers trying to get rich.
