A clickable set of Mana Gems, both to conjure missing ones and to use them. Can disable the lower rank gems if unwanted, via the "Load" tab -> check "Never" on each.

I personally don't click to use gems (I use a macro) but as a visual indicator it's great. Couldn't figure out how to stack the icons because of the buttons. Couldn't figure out how to display the 1-3 charges on Mana Emerald (devnote: GetActionCharges() and GetSpellCharges() do not seem to work).

Disclaimer: Apparently clickable weakauras are "a bad idea" and "avoided" but I've never had a bad experience. Tread with caution? xd

Mana gem macros:
