Description

宝石の観察器具及び観察方法Gem observation instrument and observation method
　本発明は、カットダイヤモンド等のカット面を有した透明度のある宝石の観察器具及び観察方法に関する。 The present invention relates to an observation instrument and an observation method for a transparent jewel having a cut surface such as a cut diamond.
　通常、カットダイヤモンド等のカット面を有した透明度のある宝石の価値は、カラー（色）、クラリティ（明澄度）、カラット（重さ）、カット（研磨）の４要素を評価することでランク付けがなされている（以下、グレーディングという）。中でもカットは、宝石に入射される光の表面反射と内部反射の方向を決定するため、宝石の輝きを決める重要な要素であり、宝石の最終的な美しさと価値に大きく影響を与えている。 In general, the value of a transparent gemstone with a cut surface such as a cut diamond is ranked by evaluating four elements: color (color), clarity (clarity), carat (weight), and cut (polishing). Attached (hereinafter referred to as grading). Among them, the cut is an important factor that determines the shine of the jewel because it determines the direction of the surface reflection and internal reflection of light incident on the jewel, and has a great influence on the final beauty and value of the jewel. .
　しかしながら、カットの評価は、上記４要素の中でも最も複雑な評価であって、技術的にとても困難なものであった。従来、宝石に施されたカットの状態は、拡大鏡を用いて視覚判別することが行われている。しかしながら、このような拡大鏡のみによるカットの評価は、高度な技量を持つ熟練者には可能であっても一般消費者には不可能であった。特に、基準が厳しく細かいグレーディングが行われるラウンド・ブリリアント・カットにおいては、高度な技量を持つ熟練者でさえ確かな評価を行うことは困難であった。 However, the evaluation of the cut was the most complicated evaluation of the above four elements and was technically very difficult. Conventionally, the state of a cut made on a jewel has been visually determined using a magnifying glass. However, evaluation of a cut using only a magnifying glass is not possible for a general consumer, even if it is possible for a skilled worker with a high level of skill. In particular, in the round brilliant cut in which the criteria are strict and fine grading is performed, it is difficult for even a skilled worker with a high level of skill to make a reliable evaluation.
　そこで、誰にでも宝石のプロポーションやカットの対称性を容易に判断することができる宝石の観察器具が種々提案されている。
　例えば、特許文献１には、略半球状の本体（１００）の中央部に孔（１０１）を有すると共に前記略半球形状の本体（１００）内に拡大レンズ（１１０）を有し、前記略半球形状の本体（１００）開口部方向に筒体（２００）を連設したことを特徴とする宝石の観察器具が記載されている（図７参照）。 Therefore, various jewelry observation instruments have been proposed that allow anyone to easily determine jewelry proportions and cut symmetry.
For example, Patent Document 1 has a hole (101) in the center of a substantially hemispherical body (100) and a magnifying lens (110) in the substantially hemispherical body (100). A jewelry observation instrument characterized in that a cylindrical body (200) is continuously provided in the direction of the opening of the main body (100) of the shape is described (see FIG. 7).
　このように構成された宝石の観察器具を用いることにより、宝石に入射される光の反射像を容易に得ることができる。そして、上記観察器具を用いて得られた反射像の模様の形状、規則性、対称性を観察することにより、カット精度の良否や宝石の善し悪し等を評価することが行われている。 反射 By using the jewel observation instrument configured in this way, a reflection image of light incident on the jewel can be easily obtained. Then, by observing the shape, regularity, and symmetry of the pattern of the reflected image obtained using the observation instrument, it is performed to evaluate the quality of the cutting accuracy and the quality of the gem.
　特に、ラウンド・ブリリアント・カットの宝石の反射像は、「ハート・アンド・キューピッド」と呼ばれ、宝石のクラウン側から観察した際には「矢」の模様が観察されることが知られている（図３参照）。 In particular, the reflection image of round brilliant cut gemstones is called “Heart and Cupid”, and it is known that the pattern of “arrows” is observed when observed from the crown side of the gemstones. (See FIG. 3).

　ところで、カット面を有した透明度のある宝石（以下、宝石という）の価値を評価する場合には、その輝き（輝度）や疵等についても確認する必要がある。
　しかしながら、特許文献１に記載の拡大視具は、反射像の模様の形状、規則性、対称性は観察できるものの、宝石の輝度や疵を観察できるものではなかった。 By the way, when evaluating the value of a transparent jewel having a cut surface (hereinafter referred to as a jewel), it is necessary to check its brightness (luminance), wrinkles, and the like.
However, although the magnified sight described in Patent Document 1 can observe the shape, regularity, and symmetry of the pattern of the reflected image, it cannot observe the brightness and wrinkles of the gemstone.

It is characterized by being.
The natural light here is not limited to light derived from nature such as sunlight or moonlight, but also includes an artificial light source in the room.
　このように、筒体は透明筒体と遮光部材を有し、遮光部材は透明筒体の軸方向に移動自在に構成されていることにより、透明筒体における自然光の入射角度と反射角度を調節することができる。その結果、宝石の反射像に現れる模様と共に、宝石の輝度及び疵を観察することができる。ここで言う疵とは、宝石の表面の疵及び宝石の内部の疵を含む。 As described above, the cylindrical body has the transparent cylindrical body and the light shielding member, and the light shielding member is configured to be movable in the axial direction of the transparent cylindrical body, thereby adjusting the incident angle and the reflection angle of the natural light in the transparent cylindrical body. can do. As a result, the brightness and wrinkle of the gem can be observed together with the pattern appearing in the reflected image of the gem. The wrinkles referred to here include wrinkles on the surface of the gemstone and wrinkles inside the gemstone.
　本発明の好ましい形態によれば、前記遮光部材は、前記透明筒体の外周に設けられていることを特徴とする。
　このように遮光部材は、前記透明筒体の外周に設けられていることにより、反射像を観察しながら遮光部材の位置を容易に移動させることができる。 According to a preferred aspect of the present invention, the light shielding member is provided on an outer periphery of the transparent cylinder.
Thus, since the light shielding member is provided on the outer periphery of the transparent cylinder, the position of the light shielding member can be easily moved while observing the reflected image.
　本発明の好ましい形態によれば、前記遮光部材は、筒状に形成されていることを特徴とする。
　このように、遮光部材を筒状に形成していることにより、透明筒体の外周を摺動する遮光部材を容易に形成することができる。 According to a preferred aspect of the present invention, the light shielding member is formed in a cylindrical shape.
Thus, the light shielding member which slides on the outer periphery of a transparent cylinder can be easily formed by forming the light shielding member in the cylinder shape.
　本発明の好ましい形態によれば、前記本体部は、内側が有彩色に着色されていることを特徴とする。
　このように、本体部の筒体側の内側表面が有彩色に着色されていることにより、観察される反射像の観察模様を容易に評価することができる。 According to a preferred aspect of the present invention, the main body portion is colored in a chromatic color on the inner side.
As described above, the observation pattern of the reflected image to be observed can be easily evaluated by coloring the inner surface on the cylinder side of the main body portion in a chromatic color.
　また、本発明に係る宝石の観察方法は、本発明に係る宝石の観察器具を用いた宝石の観察方法であって、前記拡大レンズの焦点位置に、前記宝石を配置して観察する工程を含むことを特徴とする。
　このように、本発明に係る宝石の観察器具の拡大レンズの焦点位置に、宝石を配置して観察することにより、宝石の反射像に現れる模様と共に、宝石の輝度及び疵を観察することができる。 Moreover, the method for observing a jewel according to the present invention is a method for observing a jewel using the jewel observation instrument according to the present invention, and includes a step of observing the jewel by disposing it at a focal position of the magnifying lens. It is characterized by that.
Thus, by arranging and observing the jewel at the focal position of the magnifying lens of the jewel observation instrument according to the present invention, it is possible to observe the brightness and wrinkle of the jewel along with the pattern appearing in the reflection image of the jewel. .
　また、本発明に係る宝石の観察方法は、前記遮光部材を前記透明筒体の軸方向に移動させながら観察する工程をさらに含むことを特徴とする。
　このように、遮光部材を透明筒体の軸方向に移動させながら観察することにより、宝石の輝度と疵が確認しやすい遮光部材の位置決めを容易に行うことができる。 In addition, the method for observing a jewel according to the present invention further includes a step of observing the light shielding member while moving the light shielding member in the axial direction of the transparent cylinder.

　次に、本発明に係る宝石の観察器具を使用した際の観察像について、図３を用いて詳細に説明する。まず、従来から用いられている宝石の観察器具（図７参照）を用いて得られる観察像（図３（ａ））について説明した後、本発明に係る宝石の観察器具を用いて得られる観察像（図３（ｂ））について詳細に説明する。 Next, an observation image when the jewelry observation instrument according to the present invention is used will be described in detail with reference to FIG. First, an observation image (FIG. 3 (a)) obtained using a conventionally used jewelry observation instrument (see FIG. 7) will be described, and then an observation obtained using the jewelry observation instrument according to the present invention. The image (FIG. 3B) will be described in detail.
　図３（ａ）は、従来から用いられている宝石の観察器具（図７参照）を用いて、ほぼ理想的な「ラウンド・ブリリアント・カット」が施されたダイヤモンドを、クラウン側から観察した場合に得られる観察像である。この観察像図３（ａ）に示される観察模様は、白色と色調及び明度の異なる何種類かの青色（添付写真では灰色）により構成されており、ダイヤモンドの中心から８方向に放射状に延びる白色の「矢」の模様が明瞭に現れている。このように観察される観察模様のうち、白色（矢）の領域は宝石のクラウン側から観察対象Ｄに入射される光を観察方向へ向けて反射していることを示しており、青色の領域はしていないことを示している。また、この青色の領域は、青色の筒体２００を使用したことに由来する。 Fig. 3 (a) shows the case where a diamond with a nearly ideal "round brilliant cut" is observed from the crown side using a conventional jewelry observation instrument (see Fig. 7). It is the observation image obtained by. The observation pattern shown in FIG. 3 (a) is composed of several kinds of blue (gray in the attached photograph) having a different color tone and brightness from white, and is a white color extending radially in eight directions from the center of the diamond. The “arrow” pattern appears clearly. Among the observed patterns observed in this way, the white (arrow) area indicates that the light incident on the observation object D from the crown side of the gemstone is reflected in the observation direction, and the blue area Indicates that they are not. Further, this blue region is derived from the use of the blue cylinder 200.
　一方、図３（ｂ）は、本発明に係る宝石の観察器具を用いて、図３（ａ）で観察したダイヤモンドをクラウン側から観察した場合に見られる観察像である。この時、図２に示すように、遮光部材２２を透明筒体２１他端側から少し上方位置に配置させることにより、透明筒体２１の一端側の壁面と他端側の壁面から自然光が入射される状態で観察している。

In the observation pattern shown in this observation image, the “arrow” portion corresponding to the white area in FIG. 3A is shown in pink (light gray in the attached photograph), and the other areas are called fire. It is composed of white, gray and black, which expresses the brightness (luminance) including 7 colors unique to transparent gemstones. Of the observed pattern, the pink (arrow) region indicates that light incident on the observation object D from the crown side is reflected in the observation direction, and the other portions reflect diamond in natural light. It shows the brightness (luminance) peculiar to diamonds observed when observed with. That is, the pink color appears in the observation pattern because the inner surface of the case body 11 is colored pink. In addition, the brightness (brightness) peculiar to diamond appears in the reflected image because of natural light incident from the wall surfaces on one end side and the other end side of the transparent cylinder 21 that are not shielded by the light shielding member 22.
