Abstract
A computer-implemented system is provided and includes a processor and a memory accessible by the processor, with the system being configured to measure light performance properties of a gemstone and generate an objective grade for the gemstone.
Claims33
A device for producing a reproducible identification pattern of a polished gemstone comprising:
- a platform for receiving the gemstone;
- a light source for directing a focused beam of light onto the gemstone to produce an output of the internal refraction and reflection characteristics of the gemstone including reflected light beams having particular locations, sizes and intensities;
- an automated positioning mechanism for changing a position of the gemstone relative to the focused beam of light, wherein the automated positioning mechanism is configured to change a yaw motion of the platform on which the gemstone rests by causing controlled rotation of the platform;
- and
- a first imaging device for recording the output in a manner to record the relative size and location of the reflected light beams.

- an automated positioning mechanism for changing a position of the gemstone relative to the focused beam of light, wherein the automated positioning mechanism includes:
- (a) a gimbal assembly for changing a position of the gemstone relative to the focused beam of light, the gimbal assembly including a first gimbal that is operatively coupled to a first motor and a second gimbal that is operatively coupled to a second motor and (b) a yaw frame to which the first and second gimbals are mounted, the yaw frame being free to rotate so as to move the platform in a yaw motion due to rotation of the first and second gimbals when the yaw frame rotates, wherein the first and second motors are attached to and carried by the yaw frame;
- a first imaging device for recording the output in a manner to record the relative size and location of the reflected light beams.
