In the realm of lab-created diamonds, ensuring authenticity and quality is paramount. This has led to the emergence of certification bodies like GIA (Gemological Institute of America) and IGI (International Gemological Institute). But when it comes to choosing between them, which certification holds more weight? Let’s delve into the intricacies of GIA and IGI certifications for lab-grown diamonds.

Understanding Lab-Created Diamonds

What are Lab-Created Diamonds?

In the age-old quest for the perfect gemstone, technology has paved the way for lab-created diamonds.
