International Gemmological Services

Gemmology is an evolving science comprising of necessity and to a few, a labour of love. It differentiates between the genuine and the fakes, the natural and the treated and the different varieties of the same coloured gemstones. The science of gemmology is concerned with the study and identification of gemstones and gem materials. International Gemmological Services [IGS] takes this science seriously and for that reason will follow only the grading standards enforced by the Gemmological Institute of America [GIA]. IGS gemmologists are all graduates of the GIA with a decade of experience in diamond testing and grading. IGS diamond experts are always updated with the industries latest grading procedures and in the identification of the latest man made diamond simulants.
