I listed these elsewhere and they didn't get any nibbles, so I'll post them here before discarding them since I know there are some that collect such things. They're both from the Spitfire and they've been sitting in my locker for 15ish years:

a ship shaped sapphire

a ballista shaped sapphire

They're 10k each or 15k for both to anyone in the Landing area or with Mist Harbor access.
