G-ID is capable of handling a wide range of complex materials for identification, including loose gemstones, gemstones mounted in jewelry, lab-grown materials, and imitations. When applicable, detailed information about any treatments applied to the gemstones is crucial for forming an accurate opinion. Geographic origin determination, upon request and when feasible, is available specifically for ruby, sapphire, and emerald.

To ensure the safety and traceability of your items, G-ID follows strict standard procedures. Each sample is assigned a unique series of numbers as QR-coded and is tracked throughout the entire process, from initial intake to returning to the customer. RFID technology is employed, with sample baggies tagged, enabling verification at each step and ensuring the identity matches the recorded information. This system allows all involved personnel to track the progress of the sample.

G-ID employs sophisticated technology ranging from microscopy to advanced spectroscopy, this allows our gemologists to perform all necessary analytical techniques required to properly determine its gemological identity and detect any treatments. At least two gemmologists independently perform the process of identification, an additional gemologist/specialist may be required for examination and double check principle in order to reach a consensus. 

G-ID pledges to make straightforward communication and transparent results to the public. Our gemmological descriptions conform to standards established by the international Laboratory Manual Harmonization Committee (LMHC).
