What is IGI Certificate

1. Standard Grading System
The IGI Certificate utilized accepted laboratory diamond grading standards that evaluates each stone on four criteria, known as the 4 C's.
The 4 C's are cut, clarity, colour and carat weight. The cut of the diamond is given the highest weighting of the four grades and has the most importance in the overall score. Other details included on the IGI certificate are measurements, analysis of the diamond fluorescence, its stone shape, presence of an inscription or laser treatments, and its impact on the diamond's appearance.

2. Benefits of IGI Certificate
The IGI Certificate offers several benefits aside from a grading system. It also verifies the accuracy of diamonds’ information, providing customers with confidence in their purchase. Additionally, the IGI verifies if the diamonds are laboratory-cultivated or natural mined. Other benefits include reports on the diamond’s ‘genetic programming’- the diamond’s exact crystal orientation, which identifies the optical properties of the stone.

3. Steps for Obtaining IGI Certificated Diamonds
The process for certifying a diamond with an IGI Certificate begins by submitting your sample to the nearest IGI office. Once the sample is submitted, the IGI gemologists Grade it according to 4C standards, assigning a unique identification number and making an entry in the IGI database to secure it. The diamond is observed and studied under intense magnification and the lab includes a photography of the sample for the IGI Certificate. At the end, the diamond is placed back in its individual protective pouch and sent via mail or courier to the receiver.

4. Care instructions
To preserve the quality of the IGI certifed diamond, certain precautions should be taken. Care must be taken to avoid contact with dirt, dust, grease and other foreign materials. Additionally, chemical detergents should not be used on the diamond as they can damage its surface. When diamonds are not in use, they should be kept clean and stored away properly in a cool, dark and dry place, ideally in a soft cloth or safe jewelry box.

5. Conclusion
In conclusion, the IGI Certificate was created to be the most reliable and respected source for diamond authentication and grading. It is the most widely accepted yardstick for comparing the quality of cultured diamonds, and its certification offers customers confidence and authenticity that their diamond is a genuine item. The diamond’s information is secure in the IGI database, ensuring that buyers are obtaining the most accurate assessment of the diamond’s value, quality and authenticity.
