Do diamonds need light to sparkle?

When light enters an ideally-cut diamond, the light bounces around its internal facets, bends, and exits through the top of the diamond. This is known as refraction. Refraction creates a sparkle in a diamond as a result of light bouncing around the inside, which hits your eye when the stone is in motion.

Do fake diamonds float or sink?

Diamonds are dense and will sink quickly, while certain imitations will sink more slowly. If your gem doesn't immediately sink to the bottom, it's likely a glass or quartz imitation. However, other imitations, including cubic zirconia, will also sink quickly.

Can a fake diamond pass the water test?

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.
