Description

Observation apparatus {VIEWING APPARATUS}

The observing apparatus includes a jewel case formed of a main body portion providing a jewel gemstone or a means for supporting a jewel, and a cover pivoted from the main body portion, and the jewel gemstone when the cover is closed. Or by keeping jewelry in a protective case, which is typically an opaque chain, to protect the gem or gem from damage, to some extent the gem or gem from dust, and to provide a larger unit, in particular It is known to prevent gemstones from being misplaced.

In recent years, some diamond processors have adopted the practice of marking the girdle of gemstones and, more recently, marking the table or table facet of gemstones. The mark is an information mark or indicium, such as an alphanumeric mark representing the origin or serial number of a gemstone, or a logo or trademark and / or Or a mark indicating excellent quality and authenticity. According to modern technology, the mark is formed on a flat surface, ie by removing an extremely fine amount of gemstone by milling. Milling techniques are proposed, for example, in GB 2 325 392A and WO 97/03846. The advantage of marking the flat surfaces is that these flat surfaces are inconspicuous in the decoration of gemstones. The mark can be made small enough so that the value of the gemstone is not reduced and is typically not visible to the naked eye. Nevertheless, the presence of a mark on the flat or any other side of the gemstone is an indication that a precious indicator, for example gemstone, is not synthetic and has not been processed to improve color.

There are many ways to inspect gemstone asbestos marks, but apart from the use of simple loupes, all relatively cumbersome equipment, such as the inscription loupe or magnifying tweezers, For example, you need equipment that requires the removal of gemstones from the case. It is desirable to provide a simple and convenient way to inspect the marks. It is desirable to provide a method that does not require removal of gemstones from the case, while it is desirable to provide a method that allows for easy removal of gemstones from the case, if desired. It is generally an object of the present invention to overcome or ameliorate one or more disadvantages of the prior art or to provide a useful alternative.

None of the foregoing prior art permits such prior art as it is well known in the art to which this invention pertains and forms common knowledge.

The present invention relates to an apparatus for visually observing a mark of gemstone asbestos using an external light source. In addition, the present invention relates in more detail to a gemstone for holding a gemstone such as a diamond or a gemstone decorated with a gemstone, such as a ring or an earring.

Figure 2 is a side view of the jewelry case.

3 is a cross-sectional view taken along plane III-III shown in FIG. 1;

4 is a plan view of the jewelry case with the cover removed.

The present invention provides an observation apparatus according to claims 1 to 26, and a method according to claims 27 and 28. The remaining claims claim preferred or optional features of the invention.

In accordance with the present invention, a low cost device is provided in which a conventional room light or overhead light or an outside light (light source, for example a light emitting diode) is selectively incorporated into the device. Using an external light source, and making it possible for a jeweler or the general public to see, identify, recognize or read and refer to the mark of the gemstone asbestos. In use, the user keeps the lens close to the eye, adjusts the angle of the cover member to focus on the face of the gemstone, and then observes the device to obtain reflected light from an external light source (as opposed to the reflection of scattered light). Tilt. The edge, the part of the shield that is furthest from the pivot connection, can be clamped or pressed to move, and the lens is moved through a smaller distance due to the lever effect. The magnifying lens can provide a virtual image and an upright image of the enlarged mark, and are provided so that the mark is in the correct position with respect to the axial direction of the lens. The pivot connection allows the lens to be adjusted relative to the gemstone assembling such that the gemstone asbestos is at the correct position and at an angle to the axial direction of the lens, so that the device will maintain the relative alignment of the gemstone with the lens. The device controls the positional relationship between the gemstone and the lens to allow the mark to look very easy. The pivot cover member also provides axial focus control. Compared to the positioning of a rocking gemstone or gemstone with the loupe, this focusing is very easy for the user.

Thus, the device provides a convenient way of viewing the mark and a preferred device using indoor or outdoor lighting without the need for any additional light sources. The light is irradiated at an angle to the plane at an angle, that is, at a right angle. Oblique rays of illumination can enhance the contrast of milled marks, and in some cases make it possible for the milled marks to be seen as difficult using light specular reflection.

The lens can be at a suitable magnification, for example, at magnifications greater than about 2 or 6 times and at magnifications less than about 20 or 16 times, but 10 times the lens can read most marks commercially applied. . The axis of the lens is preferably at a small angle perpendicular to the line joining the axis of such a generally inclined pivotal connection in the direction of rotation raising the edge and cover member. The angle is preferably about 2 ° or more and 8 ° or 10 ° or less.

At a distance that is about 2 times, 3 times, 4 times, or 5 times or more of the effective radius of the lens, the edges and pivot joints of the cover member may be maintained at regular intervals, respectively. The effective radius of the lens is the part available for the transmission of light. Preferably the cover member extends a considerable distance in all radial directions from the lens. In this case, the cover member may be effectively opaque, or may be effectively opaque in one or more wavelength bands, and acts as a shield to increase the sharpness of the image by reducing scattered light affecting the quality of the image. If the shield is opaque for one wavelength band, in this case the mark is more visible when viewed only at that wavelength band by placing the light source to be irradiated only at that wavelength band or by providing a filter in the light path associated with the lens, for example. Looks good. The shield extends to reduce scattered light, which generally affects the quality on the gemstone asbestos. For example, the shield may extend in all radial directions from the axis of the lens at a distance that is at least about five or ten times the effective radius of the lens (ie, the portion of the lens available for light transmission).

In a preferred device, the observation device of the present invention can normally function as a jewel case and make it possible to visually identify the mark of the flat surface of the gemstone without any additional equipment. Therefore, the apparatus of the present invention is a cover having a cover state pivoted at the body portion such that the gemstone or jewelry is in a protective case when the cover is closed and the body portion having positioning means for supporting the gemstone or jewelry It may be in the form of a jewel case made of a member. The jewelry case may be made as in claim 11. However, as another example, the observing device need not be capable of being closed in the enclosing form for gemstones or jewellery, but merely for observing the mark. For example, the viewing device may have an open end and may be arranged to allow each gemstone to be positioned under the lens and inspected in turn so that the necklace or bracelet can be moved. In this case, the positioning means only need to position the gemstone or the gemstone in a stable manner.

The pivotable connection may be in the form of a hinge with a hinge pin. However, this is not essential, and in other arrangements the pivotable connection is in one elastically deformable plastic in which the means for locating the shield and the gemstone can be integrally molded, for example. It can be provided in a manner using a hinge part.

The dependent claims optionally claim features as preferred or other forms of the invention.

With reference to the accompanying drawings will be described an embodiment of the present invention by way of example.

The jewel case 1 is a cover member or shield in the form of a cover or lid 3 pivoted from the body portion 2 by a body portion 2 and a simple hinge pin 4. It is provided. The body part 2 is embellished with a means for positioning, more particularly a gemstone 6 which represents a brilliant-cut diamond having a table 7 on the topmost layer.
