Transform your passion for jewellery into expertise with GIA

To see what that level of expertise looks like up close, we visited the world’s leading jewellery and gemstone trade fair, Jewellery & Gem World (JGW) Hong Kong. Navigating the massive event can be intimidating, but the Gemological Institute of America’s (GIA) booth offered a welcoming entry point for visitors to explore the beauty, origin, and science behind natural diamonds.

With informative displays and explanations, interactive learning corners dedicated to the journey of a natural diamond, live demonstrations of its state-of-the-art grading instruments, on-site grading services, and attentive specialists ready to answer questions, GIA’s booth offered a rare, hands-on look at how the pros evaluate these precious stones – and it makes sense why they drew in crowds during their five days at the trade event.

Founded in 1931, GIA sets the global standard of diamond grading and gemstone identification across the jewellery industry by establishing the four C’s of diamond value – colour, clarity, cut, and carat weight – along with the International Diamond Grading System™. While GIA’s grading and analysis form the backbone of industry standards, its ultimate goal is to ensure you can trust your jewellery by using the highest standards of integrity, academics, science, and professionalism. By submitting your stones to GIA’s global laboratories, each piece undergoes thorough testing that adheres to the organisation’s expertise and global standards, leaving you with a comprehensive grading report to take home.

For those investing in gemstones, a GIA report is an invaluable tool that takes the guesswork out of your next purchase. To ensure buyers know exactly what they are getting, the organisation offers dedicated assessment services across the board – covering everything from natural and lab-grown diamonds to coloured stones and pearls. After submitting your stone, GIA’s experts will use advanced technology to meticulously evaluate your gem’s four Cs, unique features, treatment, place of origin, and other specific details.
