The standard in the industry is GIA and for accuracy AGS is on par with GIA and than we got EGL which tends to be inconsistent as it competes against the two previously mentioned. Always try to compare EGL next to GIA certified diamonds so you understand and see why it’s cheaper. As a diamond seller it never made sense why so many people will not consider a GIA graded “J” color though will consider an “H” with the EGL certificate. As the same diamond graded by both labs will produce inconsistent results, one making it more saleable to the unexpected shopper than the other. Not to mention the many in house certs that are anograms of the popular certificates to confuse people like "AIG", and "EGL Intl" (no affliation with EGL USA) and appraisals from gemologist that are not reputable or adhere to any guidlines or regulations. What was your experience when comparing certs?
