Embodiment Construction

[0035] In the preferred embodiments described hereinafter, the gemstone referred to is a diamond. However, it should be understood that the present invention is applicable to the observation of any gemstone surface.

[0036] Furthermore, in the preferred embodiments described below, the viewing apparatus and method involve viewing indicia on the surface of a gemstone. However, it should be understood that the apparatus and method can also be used to observe any blemishes or irregularities on the surface of the gemstone.

[0037] Additionally, in the preferred embodiments described below, the indicia are ionized onto the table of the gemstone. However, it should be understood that the markers may be ionized to any suitable surface of the gemstone. That is, any surface capable of receiving an ionized marker that can then be positioned to cause retroreflection to occur.

[0038] refer to figure 2 , which shows the principle of retroreflection according to the preferred embod...

Abstract

Viewing apparatus for viewing a surface of a gemstone comprises an adjustable platform with a surface adapted to receive the gemstone, a viewing axis along which the gemstone is viewed, and a light source adapted to emit light substantially parallel to the viewing axis, the viewing apparatus characterised by: an alignment means comprising a plurality of misalignment indicators, the misalignment indicators arranged to provide three or more visually distinguishable zones around the viewing axis, the alignment means further comprising three or more adjustment indicators positioned relative to the platform and the misalignment indicators, wherein the adjustment indicators are associated with the visually distinguishable zones such that an image viewed along the viewing axis of one of the zones reflected off the surface of the gemstone provides an indication of which way to adjust the platform and the viewing axis relative to each other to make the surface of the gemstone and the viewing axis perpendicular to each other.

Description

technical field [0001] The present invention relates to the improvement of gem observation method and equipment. In particular, the present invention relates to an improved method and apparatus for observing the surface of a gemstone which enables the surface to be observed by providing an indication of the required adjustment of the apparatus. Background technique [0002] To ensure the quality of gemstones and the integrity of gemstone manufacturers, gemstones (e.g., diamonds) may have a quality mark, identification number (ID) or trade name (collectively referred to herein as the 'mark') ionized thereon. Any combination of these markings can be placed on the face of the stone. In this way, potential buyers of gemstones will be able to observe these markings on the gemstone and use this information to determine the gemstone's provenance. This information can help a potential buyer make a decision on whether to purchase the gemstone. [0003] An ideally cut diamond 101 i...
