Gemological Science International is involved in the diamond grading industry and uses its advanced technology and laboratories to assess diamonds. This company is different from the rest because its proprietary software grades diamonds with reduced error. Gemological Science International offers lab services, grading reports, education, and research opportunities. After careful inspection in the labs, a GSI Certificate is made available and contains information on the clarity, cut grade, measurements, and other criteria.
