Our diamond testing and grading process evaluates numerous qualities of each stone. Quality assessments are carried out by independent gemological labs, ensuring unbiased results.
We provide an accurate assessment of a diamond's authenticity and quality, including its cut, color, clarity, and carat weight. Our reports follow internationally recognized standards, with permanent treatments clearly noted in the comments section. Non-permanent treatments are not included in our IGS Diamond Grading Reports.
At IGS, every diamond is graded meticulously by experienced professionals using the GIA grading system. Our process not only covers the 4Cs but also identifies any treatments or enhancements that have been applied to the diamond. The grading is performed with precise instruments like the Proportion Scope, Master Stones, and Colorimeter.
We offer comprehensive certification services for diamonds, jewelry, and gemstones. Each certification is a testament to the quality and authenticity of the item, verified by our fully equipped gemological laboratory.
