How can you tell if a diamond is real?
To know if a diamond is real
1method - Because all you need is your eyes to perform a sparkling test, it's quick and simple. Simply place your diamond under a regular lamp and observe the brilliant glare of light that it reflects. Because it reflects white light so beautifully, a true diamond has an extraordinary shine.
2 method- Put the stone in a glass of water and see if it sinks to the bottom. Due to its high density, a real diamond will sink, while a fake one will float on the surface or in the middle of the glass.
