We all know we have to spend a significant amount of money for buying a diamond. Diamond rings and other jewelry are very commonly used even though they are costly. But how to know the diamond you are buying is worth the price? This is where diamond certifications come to play. Diamond certification is important in determining the price and quality of the diamond. We are going to explain IGI certifications for diamonds and their significance below.
About Diamond Certification
Diamond certification is the process of evaluating the properties of a diamond by an internationally accredited lab. The findings of the lab are summarized in the lab report. The report contains all information about the characteristics and physical features of the diamond.
The certification of lab-grown diamonds is similar to natural diamonds, but they mention that the diamond is lab-grown in the certificate. The grading is done based on the ‘Four Cs’ (cut, color, clarity, and carat). Each and every diamond is individually graded by the gemology labs. The diamonds can undergo several grading methods to attain the correct quality grades. The results of these individual tests are then summarized in the diamond certificate.
So it is very important to go through the diamond certificate before you purchase them. Now, let us look at the lab-grown diamond grading authorities.
Authorities Who Grade Lab-Grown Diamonds
Several internationally approved labs can grade lab-grown diamonds. These labs include the International Gemological Institute (IGI), Gemological Institute of America (GIA), Gemological Science International (GSI), etc. The standard of grading lab-grown diamonds by all these labs is similar and the certificates provided by them can be trusted.
IGI Certification For Lab-Grown Diamonds
For natural diamonds, the certification from GIA is preferred whereas, for lab-grown diamonds, IGI certification is preferred. This is because IGI provides a more elaborate range of grading lab-grown diamonds. By reading an IGI certificate, a deeper understanding of the lab-grown diamond can be obtained.
The important data in an IGI certificate are the followings.
The type and origin of the diamond are mentioned in the certificate. The details about the cut and shape of the diamond are available. The sectional division measurements which include crown height, pavilion depth, culet, girdle, etc are provided in the certificate.
Whatever data you need to know about a lab-grown diamond is available in the IGI certificate. You have to understand that each diamond is unique. IGI Certification helps you understand your purchase and enables you to make smart purchases for lab-grown diamonds.
