The International Gemological Institute (IGI) will begin issuing grading reports for moissanite through a partnership with Charles & Colvard, the first company to produce and sell synthetic moissanite.
The reports, which will cover both loose gemstones and moissanite jewellery, will feature unique identifiers that will trace them back to each laser-engraved stone, IGI said last week. The lab will use the same 4 Cs used for diamond grading — cut, clarity, carat and colour — as well as specific grading measures created by Charles & Colvard.

«This strategic alliance will bring unparalleled transparency and accountability regarding the quality of moissanite gemstones. We believe our new certifications will allow consumers, retailers, and distributors to further validate the quality and value of our gems while helping to safeguard customers against misinformation and false claims made by other moissanite providers», said Charles & Colvard CEO Don O’Connell.
In recent years, IGI has begun to release reports for synthetic diamonds, given the significant growth in the market. Just recently, it analysed and graded a 75.33-carat synthetic diamond, the world’s largest to date, which was then displayed at the JCK Show.
