Gem positioning and analysis system

A gemstone analysis system for measuring characteristics of a gemstone comprising:

• a mounting plate including a centermost point, for supporting the gemstone;
• a narrow-band spectrophotometer adapted to measure the light absorbance of the gemstone;
• a movable light source adapted to illuminate the gemstone from a plurality of angles;
• a wide-band spectrophotometer adapted to record images of the gemstone;
• and
• the wide-band spectrophotometer and narrow-band spectrophotometer further adapted to provide data to a computer system adapted to analyze the data and to output material characteristics of the gemstone.

A gemstone positioning and analysis system for measuring characteristics of a gemstone comprising:

• a cabinet;
• a clear mounting plate including a series of markings to facilitate centering the gemstone on the mounting plate;
• an alignment device including at least one linear pusher in proximity to the clear mounting plate and capable of moving the gemstone on the mounting plate;
• a camera adapted to record images of the gemstone;
• and
• a control system adapted to use images of the gemstone from the camera and control the alignment device so as to automatically center the gemstone at the centermost point of the clear mounting plate.

A gemstone positioning and analysis system for measuring characteristics of a gemstone comprising:

• a cabinet including an analysis chamber adapted to receive the gemstone;
• the analysis chamber having upper and lower hemispherical portions with a clear mounting plate between the hemispherical portions;
• the hemispherical portions having reflective inner surfaces;
• the lower hemispherical portion having an aperture at its lowermost point, the aperture adapted to allow light to pass into the analysis chamber;
• the clear mounting plate including a series of markings to facilitate centering the gemstone within the analysis chamber;
• an alignment device including at least one linear pusher and adapted to automatically center the gemstone at the centermost point of the clear mounting plate;
• a movable light source adapted to illuminate the gemstone from a plurality of angles;
• a camera adapted to record images of the gemstone;
• and
• the camera further adapted to provide data to a computer system adapted to analyze the data and to output material characteristics of the gemstone.

A method for analyzing the material properties of a gemstone comprising the steps of:

• placing a gemstone in an analysis chamber having a clear mounting plate for supporting the gemstone;
• automatically aligning the gemstone to the centermost point of the clear mounting plate;
• illuminating the analysis chamber and the gemstone from a plurality of angles;
• recording images of the gemstone;
• and
• using a computer system to analyze the images of the gemstone to determine certain material qualities and characteristics of the gemstone.

A gemstone positioning and analysis system for measuring characteristics of a gemstone comprising:

• a cabinet;
• an analysis chamber mounted in the cabinet and having an aperture adapted to allow light to pass into the analysis chamber and having a center point;
• a clear mounting plate positioned within the analysis chamber and having a series of markings including a center point;
• a movable light source adapted to illuminate the gemstone from a plurality of angles via the aperture and having a center point;
