Caesium tungstate or cesium tungstate is an inorganic chemical compound with the formula Cs₂WO₄. It is notable for forming a very dense liquid in solution (a solution containing 85.6g Cs₂WO₄ per 100g water has a specific gravity of 3.0133). The solution is used in diamond processing, since diamond sinks in it, whereas most other rocks float.
