If there’s one thing guaranteed to catch an adventurer’s eye, it’s a precious stone. If magpie tendencies seem to be running rampant, the following can be used to add a little variety to your loot or even as inspiration for a story hook. The value of the items can vary at the DM’s discretion but are suitable replacements for a handful of coinage or minor quest reward, although they could be worth more to the right person. You can roll randomly for a result below using the handy number provided with each entry to figure out your result on a d20. You can also pick one that works for the area in which your characters currently linger.
