Root Digging adds a chance when Foraging to find gems by 0.02% per action while mining. The first Root Digging buff adds a tiny chance to gain gems depending on the base foraging time.

Formula

The chance to find a random gem per action is calculated using this formula:

$GemChance={\frac {{\frac {baseActionTimeMS}{500}}+rootDiggingScrolls*100}{500000}}\times 100\%$

Without Root Digging no gems drop when foraging.
