The Assurance of Certification
 

Your confidence is our priority. The vast majority of our diamonds are independently certified by the world's leading gemological laboratories:

Gemological Institute of America (GIA): Widely regarded as the gold standard for natural diamond grading, a GIA certificate provides the ultimate assurance of a diamond's quality and characteristics.
International Gemological Institute (IGI): A highly respected authority, particularly for the grading of lab-grown diamonds. An IGI certificate offers a comprehensive and reliable assessment of your diamond's attributes.
Each certified diamond is laser-inscribed with a unique serial number, providing an extra layer of security and verifying its identity.
