Abstract
A diamond identification apparatus is disclosed, the diamond identification apparatus comprising a support platform for receiving a gemstone at an observation position, a first light source arranged to emit light at a predetermined angle towards the observation position and a first photodiode arranged to detect an amount of light from the first light source being reflected from the gemstone at the observation position. The diamond identification apparatus further comprises a second light source arranged to emit light towards the observation position, a second photodiode arranged to detect light from the second light source that passes through the gemstone at the observation position and a processor unit.
Claims22
A diamond identification apparatus comprising:
- a support platform for receiving a gemstone at an observation position;
- a first light source arranged to emit light at a predetermined angle towards the observation position;
- a first photodiode arranged to detect an amount of light from the first light source being reflected from the gemstone at the observation position;
- a second light source arranged to emit light towards the observation position;
- a second photodiode arranged to detect light from the second light source that passes through the gemstone at the observation position;
- and
- a processor unit;
- wherein the processor unit is configured to:
- determine that the gemstone is a diamond in response to the amount of light detected by the first photodiode;
- and if the gemstone is determined to be a diamond, then determine that the diamond is natural in response to the second photodiode not detecting light.
A sensor module for use in a diamond identification apparatus, the diamond identification apparatus comprising a processor unit, a support platform for receiving a gemstone at an observation position and a second light source arranged to emit light towards the observation position, the sensor module comprising:
- a first light source arranged to emit light at a predetermined angle towards the observation position;
- a first photodiode arranged to detect an amount of light from the first light source being reflected from the gemstone at the observation position;
- and
- a second photodiode arranged to detect light from the second light source that passes through the gemstone at the observation position;
- wherein the processor unit is configured to:
- determine that the gemstone is a diamond in response to the amount of light detected by the first photodiode;
- and if the gemstone is determined to be a diamond, then determine that the diamond is natural in response to the second photodiode not detecting light.
