I found these rings on Craigslist, and I took them to my family''s jeweler to have them looked at. He told me that they are around I in color and SI2. Does this seem to be correct? The center stone is .71cts, but I do not know anything about the cut. He also did not comment on the wedding bands. He just told me I got a good deal on them. I am really hoping to reset the center stone into a halo setting for an engagement ring. Would it be possible to use the other stones for the halo or a wedding band?
