Excuse the stupidity...I''m probably purchasing a diamond thru Whiteflash. I''ve found an A. Jaffe setting that I like. After I receive the diamond from Whiteflash, I bring it to a jewler who carries A. Jaffe''s line to have it set? I''m nervous about giving them my diamond. How is the consumer protected from the old bait and switch? I''m scared to have it in my hands let alone someone elses. Please inform.
