You do not need to set the pick or shovel to mine for gems. You can set it at ore or ore and granite and the special gems will still drop in your backpack. You just need to be at GM. Wearing mining gloves also helps.
The book is only for mining normal gems. Per the wiki: The book ‘Mining for Quality Gems’ bought from a blacksmith in Royal
City allows normal, jewelry gems, to be found randomly when mining with
the tool’s context menu set to ‘ore and gems’.

didn’t the mining of regular gems start before the ml gems ?
