Latest Patents

Thomas M Knobel holds a patent for a process titled "Process for irradiating gemstones." This method involves the electron-beam irradiation of gemstones for uniform color enhancement. The process requires an electron-beam source with a capacity of 500 kW, generating energy between 3 MeV to 50 MeV. The gemstones are moved in and out of the electron-beam path while the source oscillates in a direction ninety degrees opposed to the gemstones. Additionally, cooling means are necessary to prevent heat stress cracking during the treatment. This method is particularly effective for gemstones such as beryl, diamonds, quartz, sapphires, tourmaline, dark pearls, and especially topaz.
