Patent number: 8972528Abstract: A ring design machine receives one or more selections of gemstones and one or more selections of settings and allows a user to “mix and match” gemstones and settings and view a selected gemstone in a compatible setting for that gemstone. To present the gemstone in the setting, the ring design machine presents a combination image that depicts the gemstone in the setting. The ring design machine, which may be implemented using a computer programmed by software, may present the combination image to the user in response to receiving a selection of the gemstone and a selection of the setting from the user via a network.Type: GrantFiled: August 21, 2013Date of Patent: March 3, 2015Assignee: eBay Inc.Inventors: Ganga Muthyala, Belmer Perella Garcia Negrillo, Gang Han, Sarthak Dudhara, Rasesh H.
