Diamond certificate explained
Diamond Certificate
You can choose to view diamonds graded by either GIA (Gemological Institute of America) or IGI (International Gemological Institute), or you can explore a combination of both. GIA is widely recognized for its accuracy and reliability in grading natural diamonds, while IGI is known for providing comprehensive analysis of lab-grown diamonds. The choice between the two often depends on whether you're looking for a natural or lab-grown diamond, and your specific preferences and requirements.

What is Diamond Certification?
Diamond certification involves a standardised grading process by trusted experts to quantify essential characteristics of a diamond. This assists diamond buyers in visualising how a particular diamond will appear, making the purchasing process more straightforward and reliable.
Independent certification is a means of ensuring that you receive a high-quality diamond with unbiased and accurate grading.
