IGI Certificates

IGI (International Gemological Institute) is an extremely well respected and world-renowned laboratory which specialises in grading diamonds and precious gemstones.

An IGI certificate is a real 'seal of quality'. This certificate will assure you that the diamond you have chosen is nothing less than it should be.

The value of a diamond is determined through an intricate process during which its gemmological makeup, rarity and quality are examined. This is the only real way of separating one diamond from another. Experts at gemmological laboratories, such as the IGI, use powerful analytical tools and have years of experience in grading diamonds.

The diamond you are buying has been through a rigorous testing process and the independent report/certificate you receive with your jewellery confirms its true qualities.

These certificates can also be validated on the IGI website. By entering your diamond certificate number on the IGI website, you will be shown a verified copy of the report that you have.
