Abstract
A method for universally identifying gemstone cuts is provided. The method includes mounting a cut gemstone sample on a gemstone sample support, irradiating a laser beam onto a boundary between a first surface and a second surface of a measurement target gemstone, and measuring an angle between the first surface and the second surface based on an angular difference between a first diffraction component and a second diffraction component of the laser beam diffracted from the boundary.

A method for universally identifying gemstone cuts, the method comprising:
- mounting a cut gemstone sample on a gemstone sample support;
- irradiating a laser beam onto a boundary between a first surface and a second surface of a measurement target gemstone;
- and
- measuring an angle between the first surface and the second surface based on an angular difference between a first diffraction component and a second diffraction component of the laser beam diffracted from the boundary.
A universal gemstone cut identification device, comprising:
- a gemstone sample support for mounting a cut gemstone sample;
- a light source configured to irradiate a laser beam onto a boundary between a first surface and a second surface of a measurement target gemstone;
- and
- a controller configured to measure an angle between the first surface and the second surface based on an angular difference between a first diffraction component and a second diffraction component of the laser beam diffracted from the boundary.
A computer-readable storage medium containing instructions executable by a processor of a computer, wherein the instructions, when executed by the processor, cause the processor to:
- control such that a laser beam is irradiated onto a boundary between a first surface and a second surface of a measurement target gemstone;
- and
- measure an angle between the first surface and the second surface based on an angular difference between a first diffraction component and a second diffraction component of the laser beam diffracted from the boundary.
