Commitment to Confidence

IGI pioneered the grading of lab grown diamonds in 2005 and is the World Leader in the field today.

More complex than the analysis of loose gemstones, IGI’s expertise in the analysis and documentation of finished jewelry items is unrivaled anywhere. Without disassembling heirlooms or complex pieces, IGI performs thorough, objective and expert analysis of finished jewelry items

IGI screens every gemstone using state of the art technologies to determine naturally mined, laboratory grown or simulant origin. Experienced graduate gemologists conduct further assessment in controlled conditions, detailing relevant gemological characteristics according to the strictest international system. The presence of any treatments will be noted in the comments section.

For round brilliant diamonds, the overall proportions are compared with IGI studies of brightness, fire, scintillation and pattern to determine the Cut Grade. Fancy shaped diamonds are assessed using a four-step system combining finish assessment with proportions qualifications, shape-specific requirements and light return grading. All diamond shapes and colors will have craftsmanship grades for polish and symmetry noted on the grading report.

Diamond color is graded in a standardized viewing environment. IGI gemologists analyze color in the D to Z color range with the diamond placed upside down, viewed through the side, to facilitate a neutral view. Multiple graders submit opinions independently, with no collaboration, and the grade is determined when there are sufficient agreeing opinions. Diamond clarity is assessed at 10X magnification. Grading depends on the visibility, size, number, location and nature of internal and surface characteristics at that magnification. Diamonds with characteristics which are immediately obvious or noticeable are likely candidates for lower grades, whereas diamonds with characteristics which are minor, minute or extremely difficult to see at that magnification may qualify for the higher grades.

IGI co-created the modern laser inscription process. Using a very fine and precise laser beam, alphanumeric characters, a brand logo or even a personalized message can be inscribed on the girdle or outside circumference of a diamond. Adding the report number to a diamond’s girdle with Laserscribe permits fast identification of a gemstone under magnification, verifying of all of its gemological details. Now standardized as an efficient and easy way to identify a diamond, the majority of diamonds around the world have laser inscriptions.
