Microcrystalline.
Chert is a cryptocrystalline siliceous sedimentary rock. It resembles the physical properties of rocks having a glassy texture and a conchoidal fracture.
The easiest way is to find a geology book and look at the texture of each one.
Chert has no streak, it is too hard.
Chert is generally darker, and less pure.

Diagnostic features would include a Mohs hardness of around 7, conchoidal fracture, and extremely fine grained texture.
Chert is NOT a metamorphic rock.
