Fake diamonds, often made from materials like cubic zirconia or moissanite, can vary in density compared to natural diamonds. While natural diamonds are dense and typically sink in water, some synthetic alternatives may be less dense and could potentially float or sink depending on their specific composition. In general, if you want to test a stone's authenticity, other methods like examining its brilliance or conducting a scratch test are more reliable than a simple sink or float test.
