The physical and chemical makeup of lab grown diamonds matches that of natural diamonds because they possess identical properties. The use of advanced technological methods to produce these diamonds requires proper certification to validate their authenticity as well as their quality.
The IGI established early certification standards for lab grown diamonds when this innovative market segment emerged thus becoming one of the first major institutes to do so.
The main importance of IGI certification for lab grown stones exists in three essential factors.
Verified Authenticity: Confirms that the diamond is lab grown, not synthetic simulants like cubic zirconia or moissanite.
Accurate Grading: Ensures honest reporting of cut, color, clarity, and carat weight.
Global Recognition: Widely accepted by retailers and jewelers worldwide.
Resale and Insurance: An official certificate simplifies insurance claims and resale valuations.
The IGI certification process at Silveroni ensures the highest level of trustworthy documentation for our customers who want to invest in our products.
IGI implements a thorough scientific certification process for all its evaluations. The evaluation process of IGI certification follows these exact steps that occur behind the scenes.
Diamond Submission: Raw or polished diamonds arrive at the lab securely.
Initial Examination: Expert gemologists inspect the stone under magnification, identifying its origin and characteristics.
Grading: Each diamond undergoes thorough evaluation using calibrated instruments to measure:
Carat weight
Cut quality and symmetry
Color grade on the international D-to-Z scale
Clarity grade, from flawless to included
Laser Inscription: Many IGI-certified diamonds feature tiny laser-engraved certificate numbers embedded on the girdle for increased security measures.
Official Report: The lab issues a detailed certificate that travels with the diamond.
The complete evaluation procedure removes all potential uncertainty and prevents dishonest conduct and incorrect assumptions.
