20120242977 | RETAIL COMPATIBLE DETECTION OF CVD GROWN DIAMOND - A system includes a radiation source to provide short wavelength light. A holder positions a table of a gemstone to receive the light. A detector is positioned to receive fluorescent light from the gemstone when the gemstone is a CVD grown gemstone. | 09-27-2012 |
20120170019 | DETECTION OF CHEMICAL VAPOR DEPOSITION GROWN DIAMOND - Diamonds may be identified as grown by the use of chemical vapor deposition. One or more diamonds may be placed on a surface and exposed to short wavelength light. Diamonds that fluoresce red may be identified as grown by the use of chemical vapor deposition. In some embodiments, the diamonds are cooled prior to exposure to the short wavelength light. | 07-05-2012 |
20100059034 | GEMSTONE PRODUCTION FROM CVD DIAMOND PLATE - A method of producing gemstones includes obtaining a plate of chemical vapor deposition formed diamond. The plate is cut into a plurality of geometrically optimized preforms. The preforms may be finished and cut into diamond gemstones. | 03-11-2010 |
20100055022 | DIAMOND IDENTIFIER - Diamonds are embedded with one or more layers representative of an identifier. The identifier may include encoding in the form of defects created in one or more layers in a recognizable pattern, such as a bar code, characters or symbols. In some embodiments, a single crystal CVD diamond is formed with layers of varying thickness to provide the encoding. A system includes a radiation source to provide short wavelength light. A holder positions a gemstone to receive the light. A detector is positioned to receive fluorescent light from the gemstone when the gemstone is a CVD grown gemstone, and a pattern identifier correlates a detected pattern of defects to unique identification information. | 03-04-2010 |
20100053597 | DETECTION OF CHEMICAL VAPOR DEPOSITION GROWN DIAMOND - Diamonds may be identified as grown by the use of chemical vapor deposition. One or more diamonds may be placed on a surface and exposed to short wavelength light. Diamonds that fluoresce red may be identified as grown by the use of chemical vapor deposition. In some embodiments, the diamonds are cooled prior to exposure to the short wavelength light. | 03-04-2010 |
20100028556 | CHEMICAL VAPOR DEPOSITION COLORED DIAMOND - Chemical vapor deposition grown diamonds may be provided with one or more layers of doping to form colored diamonds. In one embodiment, layers of pink colored diamond may be formed by doping with nitrogen. In further embodiments, layers of yellow colored diamond may be formed by doping with boron. In some embodiments, the grown diamond has a single crystalline structure with minimal to no grain boundaries. | 02-04-2010 |
20100026985 | RETAIL COMPATIBLE DETECTION OF CVD GROWN DIAMOND - A system includes a radiation source to provide short wavelength light. A holder positions a table of a gemstone to receive the light. A detector is positioned to receive fluorescent light from the gemstone when the gemstone is a CVD grown gemstone. | 02-04-2010 |
20100000507 | ANGLE CUT ON CVD DIAMOND - A cut gemstone has one or more backside grooves cut into backside facets to form sub facets that operate to increase the brilliance of the cut gemstone. | 01-07-2010 |
