The IGL Difference

IGL is completely independent. We do not sell diamonds, nor are we affiliated with any manufacturers of diamonds. We therefore have no interest in grading loosely to boost profits.

We meticulously analyse every diamond's MAKE using the latest generation of diamond laser proportion instruments. Working to very strict and demanding parameter standards the diamond is assigned one of FOUR following categories:

  • IDEAL
  • EXCELLENT
  • VERY GOOD
  • GOOD

THE IGL DIFFERENCE
Unlike many other certification companys that will grade and produce certification for any diamond presented, IGL refuses to issue certificates to stones that fall below a certain standard. IGL's aim is to produce certificates for only high quality, naturally formed stones.
