Screenshot by Gamepur While Onyx might seem like it is hard to locate, it is actually easy to obtain. All you need to do is mine Rock Spots like you normally would around the valley. You won't get any Onyx for mining the rocks in the different biomes, those will still only get you stone. Mining Rock Spots, however, will occasionally give you an additional gem that is solid black. This gem is Onyx. Related: How to complete the Definition of a Hero quest in Disney Dreamlight Valley Obtaining this material is the same as obtaining Rich Soil or Red Algae.
