Furnaces, Fluxes and Filling: A Review of Ruby Treatment | GIA Knowledge Sessions Webinar Series

GIA Knowledge Sessions Webinar - recorded live on October 15, 2020.
Many gems are treated to improve their appearance. While treatments can be controversial, they help provide a market for a wide variety of qualities of natural gemstones, which helps keep the supply chain going. Ruby, the king of gemstones, is no exception in often being treated. The degree of treatment varies from none to minimal to a total make-over and can affect value accordingly. Follow GIA Supervisor of Field Gemology Wim Vertriest, as he explores common ruby treatments, their results and how to identify them.

About Flux...
When you size a gold ring. In order to not get fire scale on the setting. You coat the whole ring & stone in, "Jewelers helper". It's alcohol with borax dissolved in it...then when you heat the ring the flux gets heated automatically melting flux into the star sapphire...
