The Old School RuneScape Wiki also has an article on Gem rock.

Gem rocks are a type of scenery which can be mined for a random uncut gem. They are found only in northwest Shilo Village. Each gem mined yields 50 Mining experience. Mining these rocks requires level 40 Mining and completion of the Shilo Village quest. Gem rocks have a respawn time of around 2 minutes.
