How it works: Simply drop the loose stone into the water. Because loose diamonds are so dense, they should sink to the bottom when dropped in a glass of water. Many diamond fakes – glass and quartz included – will float or not sink as quickly because they’re less dense.
How should a diamond look in sunlight?

Which diamond is the rarest diamond?
