Hand Of Chayula

If I try and engrave Hand of Chayula directly from my Gem stash tab it consumes the uncut gem but does not add the gem to the tab. And I am currently at 450/500 so it's not a limit issue. It works just fine in inventory so still able to make the skill.

After some more digging it looks like the Hand of Chayula skill is only showing up under the Persistent Buff tab of the gem stash tab. So it is making the gem but if you do not have the Persistent Buff Tab filtered on it will not show it.
