Do fake diamonds sink in water? True diamonds have high density and should quickly sink to the bottom of the glass. Fake diamonds are not as thick, and therefore, more likely to float in water. This test is not always foolproof. Some materials that make up fake diamonds, such as cubic zirconia and moissanite, can sink if they are heavy enough.

This phenomenon enables diamonds to produce glows of varied colors when exposed to black light (also known as ultraviolet light). A pure and natural diamond is known to produce a blue glow when exposed to black light.
How do you test a diamond with water? This one’s easy: Get a glass and fill it with water (it doesn’t matter what type of water you use). Drop the diamond into the glass of water.
