Description

  The present invention relates to a jewel cut confirmation loupe for confirming and judging a cut state of a gem such as a diamond, and more particularly to a jewel cut confirmation loupe capable of effectively judging a cut state by enlarging a jewel.

  2. Description of the Related Art Conventionally, when confirming and determining a cut state or other states of a jewel, a method is generally employed in which a jewel is directly enlarged by a magnifying glass to make a determination.

  In addition, it is not easy for general jewelry owners to confirm the cut state of a jewel simply by enlarging it with a normal loupe.

  As described above, in the related art, in a confirmation determination method in which a gem is enlarged one by one with a normal loupe, an expert who is familiar with cutting jewels can easily confirm and determine, but a general owner can use There is a problem that it is difficult to easily confirm and determine the cut state.

  When a general owner checks the cut of a jewel with a normal loupe, it is necessary to focus while holding the loupe with one hand, and there is a problem that the check cannot be performed in a stable state.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a jewel cut confirmation loupe that enables ordinary non-expert jewelry owners to easily confirm and determine the cut state of a jewel in order to solve the above-mentioned conventional disadvantages.

  Still another object of the present invention is to provide a jewel cut confirmation loupe that enables a purchaser of a jewel to easily confirm the cut at a jewelry store and that can obtain a high advertising effect.

  In order to achieve the above object, the gem cut confirmation loupe of the present invention is configured by a translucent or transparent lower cylindrical main body and a translucent or transparent upper cylindrical eyepiece, and the main body is formed into a gem. It is characterized in that it is easy to confirm the cut by putting on the cover, the focal length can be adjusted by moving the upper eyepiece up and down, and the magnification can be changed by replacing the upper eyepiece.

  The jewelry cut confirmation loupe of the present invention has a lower opening for putting a jewel on the main body, a film part for facilitating the cut confirmation, and a removable structure for making the upper eyepiece replaceable. It features a lower retaining portion with

  The gem-cut confirmation loupe of the present invention has an upper eyepiece, a tubular part movable for focus adjustment, a retaining part for retaining the lower body and an upper eyepiece abutting part, and an upper contact part. It is characterized by a convex lens installed above the eye and a lens frame for fixing the lens.

  According to the jewel cut confirmation loupe of the present invention, an excellent effect is obtained that not only a specialist but also a general jewelry owner can easily confirm and determine the cut state of the jewel.

  Further, the cut state of the jewel 100 can be confirmed with a stable focal length.

  Further, by showing the purchaser at the jewelry store, a high advertising effect for the purchaser can be obtained.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is an external perspective view, FIG. 2 is an exploded perspective view, and FIG. 3 is a longitudinal sectional view of a jewel cut confirmation loupe according to a preferred embodiment of the present invention.

  In the figure, the jewel cut confirmation loupe according to the present embodiment includes a main body 10 and an upper eyepiece 30.

  The main body 10 is formed in a cylindrical shape with a material (for example, plastic or the like) that transmits translucent or transparent light.

  The main body 10 accommodates a film material 60 for facilitating checking of cuts therein, and has a lower retaining portion 20 for preventing the upper eyepiece 30 from coming off at an upper portion. .

  The upper eyepiece 30 is formed in a tubular shape that can be inserted into the main body 10, and has a lens frame 50 containing a convex lens 40 for enlargement at the upper part.

  As shown in FIG. 4, a transparent or translucent film material 60 of a predetermined color (a color other than black and white such as red or blue) is removably disposed on the inner wall surface of the main body 10 in a rounded state. I have.

  The main body 10 has a connecting portion 11 having a hole for connecting a string or a chain for hanging the loupe and carrying the loupe.

  The lower part of the upper eyepiece part 30 is formed with a retaining part 31 on a flange for preventing the retaining part 31 from coming out of the main body part 10, and this retaining part 31 abuts on the lower retaining part 20 of the main body part 10. This prevents the upper eyepiece 30 from coming off.

  Next, a method of using the jewel cut confirmation loupe according to the present embodiment described above will be described with reference to the drawings.

  When confirming and determining the cut state of the jewel 100 such as a diamond, first, the main body 10 is placed over the jewel 100 whose cut state is to be confirmed and positioned.

  In this state, a stable focus is maintained by moving the upper eyepiece 30 up and down to adjust the focus.

  Then, the jewel 100 is stored in the main body 10 as described above, and the jewel 100 is checked by looking through the opening 51 of the lens frame 50.

  In the jewel cut confirmation loupe of the present embodiment, the jewel 100 housed inside is enlarged by the convex lens 40, and the film material 60 of a predetermined color is arranged in the transparent or translucent main body portion 10, so that the external Since the light that has entered the main body 10 from above becomes the color of the film material 60 and hits the enlarged jewel 100, dark and light colored portions appear depending on the cut state. The cut state of the jewel 100 appears to be raised by the shading of the color of the film material 60.

  As described above, since the cut state of the jewel 100 magnified by the convex lens 40 appears and appears as beautiful shades due to the color of the film material 60, it is extremely easy to confirm and determine the cut state of the jewel 100, and to judge the cut. A person who has no experience can make a confirmation judgment of the cut state. Also, since the cut state of the jewel 100 appears as a beautiful shade of color, there is a pleasure to see.

  Further, as described above, the cut state of the jewel 100 can be confirmed with a stable focal length by fixing the main body 10 and the upper eyepiece 30.

  Further, in the sale of jewelry, if the jewelry 100 is shown to the purchaser using the jewelry cut confirmation loupe of the present embodiment, the effect of promoting the jewelry to the purchaser is increased.

  The present invention is not limited to the above-described embodiment, but can be variously modified and implemented within the scope of the technical idea.

  In the second embodiment, as shown in FIGS. 5 and 6, the shape of the lower retaining portion 20 of the main body 10 is formed in a ring shape having a cutout 21 in the lower retaining portion 20, and the upper eyepiece portion 30 is formed. Of the retaining portion 31a is formed in a projecting shape passing through the notch 21 of the lower retaining portion 20. The structure of other parts is the same as in the first embodiment.

  With such a structure, the upper eyepiece 30 can be removed from the main body 10 by turning the upper eyepiece 30 and aligning the retaining portion 31 a with the notch 21 of the lower retaining portion 20. Yes, it can be replaced with an upper eyepiece 30 of another different magnification. Therefore, by preparing a plurality of upper eyepieces 30 of lenses having different magnifications, the cut can be confirmed at an appropriate magnification according to the size of the jewel.
