Mining with Silent's Gems in the pack can clutter the inventory quite rapidly. Would it be an idea to have a kind of back pack/pouch just for the 32 gem types? With auto pickup etc. and possibly more than one stack (256 or 1024) per gem type (tiered?)?

If you are on 1.10.2, you could use Gemulation's Shinies Bag. Looks like it hasn't updated to 1.11.2 yet though.

Didn't know about that mod. Looks good. Have to check it out. Thanks for replying!
