Best Gemstone Testing and Identification?
Lab testing is very important before any gemstone or diamond is bought, it has to be certified from a good laboratory. Consumers should be wary when buying gemstones and diamonds and not fall prey to advertising tactics like celebrity endorsements, offers, and discounts; the only way to be absolutely certain is to demand an appropriate government lab certificate, which clearly states the authenticity of the gemstone and any treatments it may have undergone.

I would like to recommend an excellent gemological lab GSI https://gemscience.net/ that offer a variety of gemological services and their services are backed by ethical practices. They use the most advanced and innovative tools which are designed and built for the specific purpose of analysing and measuring diamonds related properties. They have been working in the grading industry for years and have professional and experienced staff that can create grading reports as per the need of clients in different types of formats, layouts, sizes.
