Abstract: The present embodiments relate to a modular system to sort and analyze melee sized gemstones in an automated manner. The system can use a rotating tabletop design to separate gemstones for individual analysis and sorting. For instance, a feeder subsystem can obtain gemstones, and a singulation subsystem can orient the gemstones for further processing. The gemstone can move between subsystems due to the rotation of the table. A set of metric subsystems disposed about the table can process aspects of the gemstone to derive metrics for the gemstone. Further, a sorting subsystem can sort the gemstone into a corresponding bin based on the derived metrics for the gemstone.

Abstract: Systems and methods here may be used for a setup of image capturing of a gemstone, such as a diamonds that are of high clarity grades. The present embodiments can provide methods to capture a diamond surface and internal clarity features from a diamond table and through and of other facets. Systems and methods may be used to convert gemstone dimension information into azimuth, slope, and distance information and adjust the motorized stage accordingly for surface imaging. Further, a calibration method can consider the offsets between design and actual system alignment. A calibration process can be used to compensate the offsets. Further, an additional conversion can be derived to compensate the offset caused by the geometry of the gemstone. The methods can automatically capture surface reflection images on facets of the gemstone and internal features taken through facets of the gemstone.

Abstract: Some examples herein include systems and methods of creating standards of gemstones of various classifications, which may display certain characteristics of the various classifications when excited by ultraviolet radiation and fluoresce in response. In some examples, a set of standards are created using fluorescent material, filters, and a radiation source to compare against a sample gemstone. In some examples, specific Light Emitting Diodes are selected to illuminate the gemstone samples under analysis.
