Systems and methods for mobile gemstone identification are described herein. According to an embodiment, a mobile gemstone identification system (100) includes a gemstone holder (104, 202, 302, 402) to hold a gemstone (102) and includes an optoelectronic assembly (106). The optoelectronic assembly (106) includes an illumination device (108) to illuminate the gemstone (102) by causing radiations to be incident on the gemstone (102). Further, the optoelectronic assembly (106) further includes a screen (110) to form a pattern indicative of an optical response of the gemstone (102), in response to the radiations being incident on the gemstone (102). According to an aspect, the screen (110) is formed as having a plurality of regions (114, 116) having different masses, and the pattern is to be formed substantially on a region (114) having greater mass than other regions (116).

Examples of gemstone verification are described herein. In one example, for processing a gemstone, pre-stored marking coordinates associated with a gemstone ID are obtained, the pre-stored marking coordinates generated during planning phase of the processing. Further, real-time marking coordinates for the gemstone to be processed are also obtained. An identity of the gemstone is verified based on a comparison of the pre-stored marking coordinates with the real-time marking coordinates. Further, information, including cutting parameters, associated with the gemstone ID of the gemstone is retrieved in response to a valid verification of the identity of the gemstone, for processing the gemstone.

Ring attributes may be predicted using a predictive model. A diamond selection system determines predicted ring attributes by obtaining and analyzing data related to a recipient, such as social media activity. The diamond selection system may determine search parameters based on predicted ring attributes and present a curated selection or list of candidate stones and/or settings that match the determined search parameters, for example, in a user interface of a mobile electronic device.

A system comprises a faceted structure imaging assembly and a faceted structure image analyzer. The system is configured to determine carat weight of a gemstone while in a mounted setting. In a first mode, the imaging assembly obtains a first image of a top gemstone surface. The image analyzer uses the first image to obtain at least one gemstone dimension, such as table and diameter dimensions. In a second mode, the imaging assembly obtains a second image of the top gemstone surface while a colored light pattern is reflected onto the gemstone. The image analyzer uses the second image to obtain at least one other gemstone dimension, such as crown and pavilion angles. The image analyzer uses the dimensions obtained from the first and second images to determine weight information of the gemstone. The system quickly determines gemstone weight reliably and consistently without skilled gemologists or removal from the setting.
