Gemstone verification

1. A cutting machine for processing a gemstone, the cutting machine comprising:

a processor to:

obtain pre-stored marking coordinates associated with a gemstone ID, generated during planning phase of the processing;

obtain real-time marking coordinates for the gemstone to be processed;

verify an identity of the gemstone based on a comparison of the pre-stored marking coordinates with the real-time marking coordinates; and

retrieve information, including cutting parameters, associated with the gemstone ID of the gemstone in response to a valid verification of the identity of the gemstone, for processing the gemstone.

2. The system as claimed in claim 1 , wherein the processor is to superimpose the pre-stored marking coordinates with respect to the real-time marking coordinates in a coordinate space.

3. The system as claimed in claim 1 , wherein the processor is to verify the identity of the gemstone by superimposing an image indicative of the real-time marking coordinates with an image indicative of the pre-stored marking coordinates to determine a percentage match therebetween, wherein the processor is to relatively rotate the image indicative of the real-time marking coordinates with respect to the image indicative of the pre-stored marking coordinates to compare at predetermined intervals of rotation.

4. The system as claimed in claim 3 , wherein the processor is to detect a table line of the gemstone, based on a best-match position of the image indicative of the real-time marking coordinates relative to the image indicative of the pre-stored marking coordinates.

5. The system as claimed in claim 3 , wherein the percentage match is compared to a threshold match to determine a best-match for verifying identity of the gemstone.

6. A method for processing a gemstone, the method comprising:

receiving a marked gemstone, the marked gemstone having markings formed thereon in a planning stage of the processing, wherein the markings are based on marking coordinates associated with the marked gemstone;

obtaining a set of pre-stored marking coordinates from a database for all planned gemstones;

generating real-time marking coordinates for the marked gemstone;

determining best-match pre-stored marking coordinates, based on a comparison of each of the marking coordinates in the set of pre-stored marking coordinates against the real-time marking coordinates; and

retrieving information, including cutting parameters, associated with a gemstone ID linked to the best-match pre-stored marking coordinates, in response to a valid verification of the identity of the gemstone, for processing the marked gemstone.

7. The method as claimed in claim 6 , wherein the determining comprises superimposing the pre-stored marking coordinates with respect to the real-time marking coordinates in a coordinate space.

8. The method as claimed in claim 6 , wherein determining comprises superimposing an image indicative of the real-time marking coordinates with an image indicative of the pre-stored marking coordinates to determine a percentage match therebetween, wherein the superimposing comprises relatively rotating the image indicative of the real-time marking coordinates with respect to the image indicative of the pre-stored marking coordinates to compare at predetermined intervals of rotation.

9. The method as claimed in claim 8 , further comprising detecting a table line of the gemstone, based on a best-match position of the image indicative of the real-time marking coordinates relative to the image indicative of the pre-stored marking coordinates.

10. A non-transitory computer readable medium comprising instructions executable by a processing resource to:

receive data corresponding to a marked gemstone, the marked gemstone having markings formed thereon in a planning stage of the processing, wherein the markings are based on marking coordinates associated with the marked gemstone;

obtain a set of pre-stored marking coordinates from a database for all planned gemstones;

generate real-time marking coordinates for the marked gemstone;

determining best-match pre-stored marking coordinates, based on a comparison of each of the marking coordinates in the set of pre-stored marking coordinates against the real-time marking coordinates; and

retrieve information, including cutting parameters, associated with a gemstone ID linked to the best-match pre-stored marking coordinates, in response to a valid verification of the identity of the gemstone, for processing the marked gemstone.
