>>1758181I deal with estate property regularly. Most portable property (furniture, clothes, etc) doesn't keep its value. Gems aren't an exception.
I'm not an appraiser, so I can't tell you if anything there is worthwhile, but I suspect at a minimum that the big rock-looking pieces are worthless. To the extent there is anything valuable there, my guess would be that we're talking a maximum of <$1000 all in.
But hey, they look cool and maybe they have sentimental value for you. That's enough of a reason to keep them if you don't mind storing them. The pair of little red ones in the middle look like they could be set in something if you ever have someone you'd wanna give a family heirloom to.
