Gem Testing Services

Certification of Colored Gemstones


The CIGS "Certificate of Gem Identification" is a visually stunning report that accentuates the value of your precious gemstone by highlighting its rarity and natural beauty. It provides comprehensive identification details, including a full-colour gemstone image, physical and tested data, gemstone identification, and opinion on thermal enhancement or CIGS colour type if applicable.

Special Color Reports


Colour types encompass a range affected by various factors like cutting, clarity, pleochroism, and fluorescence. "Out of gamut" colours are not reproducible. Special colour terms are not awarded for treated gemstones. CIGS grades this colour range for both heat-treated and unheated gemstones.

Consultation


Our personalized gem and jewelry consultation service provides expert guidance and advice to help you find the perfect gemstone or create a unique custom design. Our experienced gemmologists and designers will assist you in understanding gemstone qualities, styles, and options, ensuring that you make an informed decision and create a stunning piece that reflects your individual taste and preferences.

Beryllium Treatment


The beryllium diffused sapphire caused concern as it permeated the gemstone, challenging identification. GIC's LIBS technology enables accurate detection, analyzing specific wavelengths emitted by vaporized samples

Stone Heat Treatment Testing


Natural sapphires acquire colour through trace chemicals during the natural process of heat and pressure. Heat treatment, a common industry practice, improves clarity and colour without using chemicals. Fourier-Transform Infrared Spectrophotometer is a crucial tool for detecting gemstone treatments.

Other Treatment Testing


In addition to the treatments mentioned, CIGS is equipped to test and identify other treatments including fracture filling, lattice diffusion and oil impregnations.
