How can you tell if a diamond is real at home?
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. Due to the high density of diamond, when dropped into water a real diamond will sink. If the diamond floats to the top or middle of the glass, it’s fake.

How can you tell difference between diamond and cubic zirconia?

How can you tell if a diamond is real by water?
Water testing your diamond
