The Gemlab diamond certificate is essentially a warranty of the authenticity of a diamond and a reliable and accurate statement of its identity and grade based on a world wide standard.
Each diamond is analyzed by gemologists who use their own knowledge in combination with the best equipment today available to produce an accurate analysis of the characteristics of the diamond and the quality of its cut.

 

 

The grade of a diamond is based on four characteristics, internationally commonly referred to as the 4C's: the Carat weight, Color, Clarity and Cut.
