About Us

The World Gemological Institute (WGI) was established to provide professional, precise and efficient gemological services to the global jewellery industry with our newest headquarter laboratory located in the heart of London’s diamond district, Hatton Gardens.

Over years the expert Gemologists at World Gemological Institute (WGI) have built a solid standing reputation as one of the leaders in the Industry.  Our appraisals and lab reports are recognized worldwide by insurance companies, retailers, private jewellers and wholesalers.  We offer a number of different appraisals and comprehensive laboratory services to suit our customers’ needs.

Gemologists

All of our Gemologists are graduated from the Gemological Institute of America (GIA) and have many years of industry experience. Our staff is required to continually improve upon their education by regularly attending seminars, lectures and advanced gemological studies, including the coveted and highly regarded Fellowship (FGA) through the Gemological Association of Great Britain (Gem-A).

 

Our Goal

Our goal at WGI is to accurately identify and evaluate diamonds and gemstones and distinguish if they have been treated prior to your purchase.

When you consider the high cost of gemstones and jewellery, it makes good sense to have them evaluated by a professional, unbiased and reputable company.  We have saved our customers agonizing regret and thousands of dollars over the past 30 years with our detailed evaluations and assessments.  We take a great care with customer’s precious items and details with the high standard of integrity.

Please call today to set up an appointment or to speak with one of our Gemologists.
