Go with the consignment shop. That is an opportunity with the best shot. The guy online examining and appraising your gems means you are competing with Asian cut gems. Don’t compete- stand out. Taking your gems to a bench jeweler or fine jeweler is a good idea. Don’t be put off when the jeweler says no- just ask why and if it’s the quality, work on it.
Sorry your gems are not selling now, but neither is anyone else’s. Be aware this is a hard time for the jewelry industry. This is an industry still shrinking, due to poor sales all across the country. These are known retailers and wholesalers.
