Welcome to Cyprus Gemological Laboratory (CGL)
The diamond industry is a global business and its growth in recent decades has been matched by the development of specialised gemological laboratories dedicated to the identification, grading and certification of diamonds using advanced technology.
The Cyprus Gemological Laboratory (CGL) is a modern gemological facility providing precise, high-quality testing and appraisal services to the diamond and gemstone market of the Eastern Mediterranean.
Our Gemological Standards & Online Verification
In line with international gemological practice, CGL certifies both natural and laboratory-grown diamonds, grading each on the 4Cs: carat weight, cut, colour and clarity. Every certificate clearly states whether the diamond is natural or laboratory-grown.
Every CGL certificate is a signed, detailed record of your gemstone based on rigorous scientific analysis, advanced laboratory instrumentation and the professional expertise of our resident gemologist. Each certificate is securely stored in our laboratory database and can be verified online.
All grading, identification and treatment findings represent the professional opinion of our gemologist at the time of examination. Results from other laboratories may differ due to differences in equipment, methods and examination conditions. Full terms are printed on each CGL certificate.
Trusted Regional Expertise
CGL provides a full suite of specialised services for the scientific identification, grading and valuation of loose diamonds, coloured gemstones and fine mounted jewellery.
Through our professional membership of the International Gem Society (IGS), our extensive gemological experience and our specialised testing equipment, CGL has established itself as a trusted regional gemological laboratory serving both private clients and the fine jewellery trade.
