Since Stone Picking as a skill is going to get deleted with the Cleric balancing update patch,
How about recycling the Yak Warrior gem for Kabbalists Double Chance, which became a Rank 7 skill with the patch?
If yes, please consider making it a weapon/boots or top/bottom gem, because there are already too many Cleric skills fitting into weapon&gloves gem sockets, while there is only a small amount of skills occupying boots, shield/sub-weapon or top/bottom body armor sockets.
