1. A method comprising:
receiving structure characteristic information of a gemstone;
supplying light directly onto a table facet of a gemstone via a coaxial light assembly;
supplying uniform light to the gemstone via a diffuse dome assembly without directly illuminating the gemstone;
generating an image of a surface of the gemstone; and
estimating weight of the gemstone based on the image of the surface of the gemstone and on the structure characteristic information, wherein estimating weight of the gemstone based on the image occurs in response to detecting a foot pedal input, wherein no other user input is involved in estimating weight of the gemstone other than the structure characteristic information and the foot pedal input, and wherein estimating weight of the gemstone involves determining whether to apply watershed segmentation to identify a boundary of the gemstone in the image.
