How to tell if a Diamond is Real or Fake ?

Updated: Aug 7, 2023

When it comes to buying a diamond, it is essential to be able to distinguish between a genuine diamond and an imitation. Learn about the characteristics and methods that will help you make informed decisions when purchasing diamond jewelry.

Dazzling Brilliance: The First Sign of a Real Diamond

The first step in identifying a real diamond is to observe its brilliance. Authentic diamonds reflect light spectacularly, creating a sparkling shimmer. In contrast, imitations made of glass or plastic often lack brilliance and have a dull shine. Use a light source to assess the diamond's brilliance.

Unmatched Hardness: A Crucial Test to Authenticate a Diamond

Another crucial aspect to consider is the hardness of the diamond. Diamonds are the hardest natural substance on Earth. Perform a scratch test by rubbing the presumed diamond against glass. If the glass cannot resist scratches, it is a genuine diamond.

Clarity and Color: Revealing Clues of a Diamond's Authenticity

Examining the clarity and color of the diamond is equally important. Genuine diamonds typically display crystal clarity with few visible inclusions to the naked eye. In terms of color, high-quality diamonds are often colorless or slightly tinted. The presence of dark spots, inclusions, or unusual color may indicate a fake diamond.

When purchasing diamond jewelry, the ability to distinguish a real diamond from an imitation is crucial. By evaluating brilliance, hardness, clarity, and color, you can make well-informed decisions.
