NEED HELP.

I posted once in this group about my 40 carat star sapphire and it got really good responses! I currently reside in DC and due to an emergency, have to sell some of my rings. The first one is a 57 carat star ruby and then the others are around 6-7 pieces of natural alexandrite stone. Problem is, everywhere I’ve called near me want nothing to do with it and not buy it and I don’t know what to do. At this point, I’m willing to fly out to anywhere in the States if I have to. Can anyone tell me if there’s any worth in these rings? Much appreciated.
