    State-of-the-Art Resourceful Unmatched


GIC is well equipped with the state-of-the-art equipment and tools, so we can test and analyze any type of gems up to the highest international standards.

  • Capturing High Resolution Data GIC,Sri lanka


    One of the most powerful instruments use in today’s testing laboratories. FTIR is used to measure absorption in materials within the infrared part of the electromagnetic spectrum. When Infra-red radiation is passed through a sample, some of it is absorbed by the sample and the remaining will be transmitted. The resulting spectrum represents the molecular absorption and transmission, creating a molecular fingerprint of the sample.

    This technique is a non-destructive fast, reliable and easy technique in:

    • Detection of gem materials.
    • Distinguish certain natural and synthetic gem materials, e.g. emerald, Quartz.
    • Opinion on heat treatment on ruby and sapphire.
    • Detection of oil, resin and polymer impregnation in Emerald and jadeite.
  • Measuring the Light Absorption Accurately GIC,Sri lanka


    Absorption patterns within the UV radiation range of the gemstone are utilized in this method.

    The non destructive UV-VIS spectroscopy is used in:

    • Detection of gem materials.
    • Opinion on heat treatment of sapphire.
    • Opinion on colour variety of gems.
    • Helping tool in origin determination of emeralds and sapphires (certain different origins may produce different absorption patterns).
    • Identification aid for minerals.
  • Significantly Lowering the Cost of Beryllium Testing GIC,Sri lanka


    LIBS is an elemental analysis instrument with a good throughput to detect Be in Corundum. Its mechanism is to analyze the spectrum of the plasma of each element. The ultraviolet (high energy) laser vapours the quite small spot of sample (50-100um). The vapoured gas of element is excited with the laser (ablation) and transform to plasma state (ionized gas by high energy). And then the excited plasma returns to normal gas state with emitting some specific light for each element.

  • Studying Gemstone Inclusions GIC,Sri lanka


    Raman scattering or the ‘Raman effect’ is the inelastic scattering of a photon upon interaction with matter. When a ray of light passes through a gem material, a tiny amount of light is scattered and changes in wavelength. This scattering has the same energy (frequency and wavelength) as the incident photons. One in ten millionth of those scattered photons shifts to a different wavelength and this shift generates a spectrum which we could use to identify gem materials.

    Raman Spectroscopy is a non-destructive tool for fast, reliable and easy for:

    • Identification of gem materials (whole or parts of the material) and imitations.
    • Ideal for identification of cut & polished gems but also could be use to identify rough materials.
    • Identification of loose or mounted gems.
    • Identification of Inclusions.
    • Identification of impregnation of oil and resins in Emeralds
