This has been updated for RimWorld 1.5, if anyone cares
Makes gems a "small volume" item and changes their mass to be appropriate. Without any modded gems, this only affects Jade.
If [url=https://steamcommunity.com/sharedfiles/filedetails/?id=1339121712&searchtext=extra+gems]Kura's Extra Gems[/url] is loaded before this one, all the gems in that mod will be small volume items as well.
I might support other mods in the future, if there is a demand for it.
