NYG (New York Gemological Laboratory Resources) is a non-profit Laboratory and Resources center and is likely, one of the most recognized and respected organization of all the Gemological labs worldwide.
Graders are always on the lookout for simulated stones, synthetic gems and stones that have been treated in some way to enhance their appearance, such as the treatments that are commonly applied to create a new or more vivid color.
However, once you grasp the basic principles, you will wonder how anyone could buy a gemstone without using this kind of vocabulary.
The NYG Colored Stone Report clearly states whether the stone is natural or synthetic.
It also provides other data describing its shape, cut, weight, measurements, color, transparency and major optical characteristics, and also includes a detailed photograph of the stone.
Gemstones should only change hands when accompanied by a certificate attesting to quality. Regardless of location or marketplace, an authentic IGI Laboratory Report is the common language of trust and confidence in the gemological world.
NYGL report also provides detailed information about the dimensions, carat weight, shape, cut, and enhancements of a stone.
NYGL reports also include an illustrated diagram of the stone that shows cut and clarity information.
NYGL certification also provides information on the stone's country of origin, and identifies any gemstone enhancements or treatments.
