Diamond Certificates

Ensuring your diamond is certified by one of the leading independent and recognised certification laboratories is essential for an unbiased assessment of the stone’s quality. GIA, HRD, IGI & EGL are the leading grading bodies in the diamond industry, and are listed here in order of strictness. Today, expect most diamonds over 0.20ct to be graded by one of these.

Even amongst the 5 internationally recognised certificates, there are differences. In fact, the diamond industry benchmarks every diamond against the GIA’s (Gemological Institute of America) strict standards. Comparing a diamond with a GIA certificate against an IGI or the weaker EGL is not an equal comparison. So like-for-like colours or clarity grading on EGL would be graded 2/3 grades lower if sent to GIA and therefore should reflect lower prices

IGI – International Gemological Institute
One of the leading gemological institutions in the world, the IGI was established in 1975 in Antwerp, with a sister laboratory in New York, and has since become the largest independent gem certification and appraisal institute renowned for its quality services, extensive experience and expertise. What originally began with just 3 staff members has expanded to over 250 professionals dedicated to a remarkable standard of excellence in Antwerp, New York, Bangkok, Mumbai and Tokyo

International Gemological Information, a division of IGI, was established in New York in 1981, as a source for unbiased appraisals of gems and jewellery. Like its parent company, IGI Information is totally independent of all commercial sales organisations and does not trade in diamonds or precious stones. Therefore IGI Information is able to provide objective and accurate appraisals and identification reports, alongside appraisal updates and estimates in case of damage.
