摘要： A system for the automatic grading of a cut/polished gemstone (SUT) includes an enclosure with a stage for mounting the cut/polished SUT. The enclosure further includes one or more sources of broadband visible (BBV) light, the sources of BBV light being controllable by a programmable controller; an image sensor for capturing a plurality of images of a mounted SUT, and one or more sources of UV light mounted within the enclosure. The controller captures images of the mounted SUT from one or more selected angles relative to the sensor elevation axis and relative to the position of the SUT on the stage rotation axis; an image capturing module is configured for processing the one or more images; and, a light grade calculation module is configured for grading the cut/polished SUT using light indicative parameters from at least a part of the one or more images captured.

摘要： The application provides a gemstone testing apparatus for testing a specimen. The gemstone testing apparatus includes a handheld casing, a plurality of light sources, a test probe, a photodetector, a processor unit, and a display unit. The test probe is placed at one end of the handheld casing. A first end of the test probe is placed outside the handheld casing. The plurality of light sources is provided for emitting light rays towards an area that is in the vicinity of the first end. The first end is adapted for receiving light rays from the specimen and for transmitting the light rays to a second end of the test probe. The photodetector is arranged to measure an intensity of the light rays from the second end. The processor unit is provided for determining a material of the specimen in accordance to a measurement of the intensity of the light rays.

摘要： A multi-functional precious stone testing apparatus includes a portable housing, a testing unit, and an indication unit. The portable housing includes a hand-held casing and a probe casing extended from a front end of the hand-held casing. The testing unit includes a conductive probe having a testing end portion extended out of a tip end of the probe casing for contacting a testing object to determine a conductivity of the testing object. The indication unit includes a LED light unit received in the hand-held casing for illuminating the testing end portion of the conductive probe during testing, wherein the LED light unit is positioned away from the tip end of the probe casing for preventing heat generated from the LED light unit being transmitted toward the conductive probe to affect an accurate measurement for the conductivity of the testing object.

摘要： A magnifying device for jewelry and system for use of the same are disclosed. In one embodiment of the magnifying device, a securing ring is coupled to a body to selectively attach in a snap-fit engagement with a gem tester. A hinge assembly is also coupled to the body and a support frame is pivotally coupled thereto. A seat within the support frame defines a circular opening securing a magnifying lens therein. The support frame also includes a pivot blade extending therefrom that accepts rotational bearing force to cause the support frame and therefore the magnifying lens to rotate relative to the body.

摘要： Technology is disclosed for use in diamond processing. Diamond parameter information is obtained and information for numerous diamonds can be aggregated into a database. At least one candidate diamond for potential recutting is identified based on processing the received measurement information by applying logic based on selection criteria stored in the memory. A virtual model is then generated of the at least one candidate diamond based, at least in part, on the received measurement information. The virtual model is analyzed by applying recut criteria to determine a parameter indicative of recut potential and this is output for use in selecting diamonds for a recutting operation. By reducing the requirement to transport diamonds to an analysis site, significant energy, processing, and environmental benefits may be achieved.

摘要： A gem tester for testing a gem under test and a kit including a horizontal recharging stand are disclosed. In one embodiment of the gem tester, an elongated body has a line-of-sight contour tapering from a bulbous end to a radially deviating frontal nose having a probe extending therefrom. Internal circuitry measures electrical and thermal conductivity of the gem under test in order to identify the type of gem under test and drive a color control signal in response thereto. A luminescent mounting extends about the contact to provide, in response to the control signal, a color indication of the identified gem type.
