What Is IGI?
The International Gemological Institute (IGI) is one of the world’s largest and most well-known diamond grading laboratories. Founded in 1975 and headquartered in Antwerp, Belgium, IGI provides certification for diamonds, colored gemstones, and jewelry. While it is known for grading both natural and lab-grown diamonds, IGI is particularly prominent in the lab-grown diamond sector.
Key Features of IGI:
- Diamond Grading: IGI evaluates diamonds based on the 4Cs Carat weight, Cut, Color, and Clarity similar to other major labs. They provide reports detailing these characteristics, helping buyers understand the quality of their stone.
- Colored Gemstone Certification: In addition to diamonds, IGI certifies colored gemstones like sapphires, emeralds, and rubies, offering a detailed analysis of their origin, treatments, and characteristics.
- Jewelry Certification: IGI certification also offers complete jewelry evaluations. They assess the entire piece, including the quality of the diamonds or gemstones used, metal purity, craftsmanship, and design.
- Global Reach: IGI has laboratories and schools around the world, including major locations in New York, Hong Kong, Mumbai, Dubai, and many more. This makes it one of the most accessible and widely recognized certification institutes globally.
- Lab-Grown Diamonds: IGI has become the leader in grading lab-grown diamonds, which have gained popularity in recent years. Many jewelers and manufacturers rely on IGI to certify these diamonds, especially because of its expertise in this area.
- Grading Leniency: Compared to the Gemological Institute of America (GIA), IGI is often considered a bit more lenient in its grading standards. As a result, diamonds graded by IGI may sometimes appear to have slightly higher grades for characteristics like color or clarity than they would receive from GIA.
- Affordable Certification: One of IGI‘s strengths is offering a more cost-effective certification option, making it popular for lab-grown diamonds and more affordable gemstones or jewelry.
IGI Reports Include:
- Grading of 4Cs (Carat, Cut, Color, Clarity)
- Diamond Identification (natural or lab-grown)
- Laser Inscription (optional, for identification)
- Proportions and Measurements (depth, table, girdle, culet, etc.)
- Symmetry and Polish
- Fluorescence
IGI in the Market:
While IGI is widely respected and offers detailed, professional certification, it’s often seen as more consumer-friendly and budget-conscious compared to the stricter GIA. IGI’s reputation is especially strong in the lab-grown diamond industry, but it’s not as highly regarded for natural diamonds due to its more lenient grading.
IGI certification
IGI certification entails a thorough evaluation and grading of a gemstone or jewelry item to ascertain its quality and authenticity. This process involves assessing the color, clarity, cut, and carat weight of the gemstone, as well as any potential treatments or enhancements it may have undergone.
The purpose of IGI certification is to offer buyers an unbiased and comprehensive evaluation of a diamond’s quality, enabling them to make well-informed purchasing choices. Furthermore, it serves to prevent fraud and dishonesty in the gemstone industry by establishing a consistent framework for evaluating and grading gemstones.
In summary, IGI is a reliable certification body with global influence, particularly for affordable and lab-grown diamonds, but it’s not considered as strict or prestigious as some other labs, like GIA, for high-value natural diamonds.
What is GIA?
The Gemological Institute of America (GIA) is the most respected and recognized authority in the field of diamond, gemstone, and pearl grading and certification.
