I keep building up a bunch of orb gems now that I bothered to have my Bard sing my emeralds and diamonds. I'd just sell them to the gemshop for 10k, but orbs aren't worth as much as non-orbs for some crazy reason. Anyway, if you need some orbs for chrisms or such, let me know. I usually have a bunch available for 10k each. I only keep the emeralds, diamonds and rubies but if you have a preference, just let me know. You can look for Erstweal in game, he hangs out in Icemule, but can meet you on FWI.
