Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a portable, small-sized and versatile device for observing diamond cutting patterns and other jewels, whether they are good or bad, flaws, foreign substances, or whether they are genuine or not.

[0002]

[Prior art]

 Conventionally, when observing such expensive jewelry cut patterns and flaws, whether it is a genuine article or a fake article, jewelery specialty stores use a large observation instrument, but at stores and on the go. It is normal to use a magnifying glass when watching at.

[0003]

[Problems to be solved by the device]

 However, when using a loupe, it was impossible to accurately observe the details of the diamond cut, even with a magnifying glass with good magnification. This is due to the fact that a shadow caused by light creates an invisible position.

[0004]

[Means for Solving the Problems]

 The inventor arrived at the present invention as a result of continuous research over many years for developing an accurate gem observing device that can be used at such stores and on the go, and the diamond cutting is good or bad. Obviously, all colored gems such as rubies and opals, pearls and other gems can be observed in a compact and portable size, and not only light from one direction but also reflected light can be used to make lenses. It is intended to provide a multi-purpose gem observation device that can be viewed through.

[0005]

[Action]

 The observation device of the present invention is about the size of a cigarette box, this box is divided into upper, middle, and lower three stages, a lens tube is provided on the upper step, and fluorescent paper is attached to the inner surface of the lens tube, and the middle step is While a step for mounting a jig suitable for the type of jewelry is provided, a mirror is installed on this side, and a miniature bulb is used as the battery box in the lower step. In addition, a color filter is used in place of the lens to judge whether a colored gem such as ruby or opal is a natural stone or an artificial stone.

Therefore, when the switch is turned on and the light bulb is turned on, the light is observed from the lens or the color filter in the upper stage through the jewelry arranged on the jig, but this light is reflected by the mirror provided in the middle stage. The light shines on the jewel from the side, and is diffused by the fluorescent paper on the inner surface of the lens barrel, so that the jewel can be seen as if it were seen through the lens.

When the observation device of the present invention is used, not only transparent jewels such as diamond, but also opaque jewels such as opal and colored jewels such as rubies and emeralds, Even jewels such as pearls can use the reflection of light to detect the appearance of cuts, determine whether they are natural stones or artificial stones, and discover the presence of defects.

【Example】

 The gem observing device of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a front sectional view and FIG. 2 is a side sectional view. In addition, Fig. 3 and subsequent figures show plan views of jigs used according to the type of jewelry.

In FIG. 1 and FIG. 2, A is a main body and is about the size of a cigarette box as a whole, and there is no partition plate in practice, but it is divided into upper, middle, lower three stages, and the upper stage (1) The lens barrel (4) is mounted on the upper lid (10) that slides left and right, and the stone on the jig can be seen accurately by sliding. A lens (5) is mounted on the upper part of the lens barrel, and fluorescent paper (9) is attached to the inner surface of the lens barrel. The color of the fluorescent paper (9) is not particularly limited, but bright fluorescent paper such as red or yellow is preferable. And in the case of colored jewels, color filters are used instead of lenses.

Further, the middle step (2) is a hollow portion, and several steps (6) for suspending a jewel jig described later are provided, and a mirror is attached to this side surface. This mirror is required to be provided on at least two side faces in order to effectively use the reflected light. Therefore, one side of the jig should be slid upward for convenient handling.

Further, the lower stage (3) is a battery box, in which a battery (7) is housed, a miniature electric bulb (8) is provided in the center, and a light bulb is turned on by turning a switch (not shown) on and off. Flashes.

Next, the jig B shown in FIG. 3 and subsequent figures will be described. Jig B-1 and Jig B-2 are jigs for die and are made of transparent plastic and selected according to the size of diamond stone, and B-1 is used for small stones. B-2 is suitable for large stones. In addition, the jig B-3 is a jig for exclusive use of a finger ring, and the ring portion is dropped into a horizontally long hole in the center and suspended. Further, the jig B-4 is a milky white opaque plate and is used for colored stones and opaque stones. In the case of this colored jewel, a color filter (not shown) is used instead of the lens (5). Then, the plate B-5 having the lens (12) inserted therein is suspended at the lowermost stage.

The plate B-5 in which this lens is attached uses a short focal lens with high magnification for contacting the miniature light bulb (8) arranged in the lower stage of the lens barrel (4) provided in the upper stage. Together with the lens (5), it increases the expansion rate.

[0014]

[Action]

 The portable multi-purpose gem observing device of the present invention is configured as described above, and when the switch is turned on and the light bulb is lit, the light from the light bulb is observed from the upper lens through the jewel located in the jig B. This light is also reflected from the side by the reflection of the mirror provided in the middle, and not only the quality of the diamond itself and the quality of the stone itself, but also opaque stones such as pearl and opal. By using a color filter, it is possible to judge whether the stone is natural stone or artificial stone, and to observe flaws, etc. Furthermore, the light appears to be scattered by the fluorescent paper attached to the inside of the lens tube and the stone appears to rise. As a result, it is possible to observe accurately even the fine parts of the diamond and the quality of the stone itself, and since it is small and convenient to carry, compared to the observation with a conventional magnifying glass. Observations achieved a breakthrough work for the effect that it can be accurate even in the over-the-counter and go.
