The ICA | GemLab Journal
Volume 2 Issue 3
This edition of our journal is a captivating journey into the world of gemstones, where we explore Mozambique’s ruby mines and the intricacies of international auctions while gaining invaluable insights into the dynamics of the gemstone market. Beginning with a comprehensive Auction Report on Fura Gems, we delve into FURA’s Colours grading systems and offer an insider’s view of their Mine to Auction process.
Furthermore, our two-part series on Provenance Proof highlights the harmonious fusion of advanced technology and traditional practices, forging a secure and transparent chain of custody that marks a significant step towards an accountable gemstone industry. We are also excited to introduce “GEM NERDS,” a new segment for gemstone enthusiasts, featuring articles on topics like cobalt spinel space inclusions and the utilization of fluorescence and iron content for potential provenance verification.
It’s a must-read for all gemstone lovers, gemmologists, and those passionate about transparency and knowledge in the world of precious stones.
On Origin determination
In order to determine the origin of a gemstone, the mineralogical and gemological properties collected during the testing is vital information.
Our gemologists take this data to compare it with our vast database, narrowing down the specific gem bearing localities around the world
