Original 1940s advertisement from Union Carbide & Carbon Corporation showcasing the innovative use of synthetic sapphires and rubies developed during WWII. Titled “What Else Is in Store for These Man-Made Gems?", the ad highlights how Linde synthetic gems, once used to replace scarce wartime imports, found surprising applications in textiles, timepieces, navigation instruments, and even jewelry. Vivid illustrations show the gems' roles in precision engineering and elegant adornment. A fascinating piece of wartime industrial history. Approx. 6 x 10".
