Abstract

Disclosed is a jewelry cut structure that breaks the existing concept and creates a new aesthetic value by eliminating curettes, which can cause unexpectedness and interest.
A peeping surface is formed on the top of a crown, and a decorative surface is formed on a lower part of the pavilion so as to face the peeping surface. Thereby, when viewed from the crown 2 side, the decorative surface 31 of the pavilion 3 can be visually recognized from the viewing surface 21 of the crown 2. Further, the decorative surface 31 of the pavilion 3 is smaller than the peeping surface 21 of the crown 2. For this reason, the light that has entered the interior of the jewel from the peeping surface 21 is reflected by the facet 32 on the side of the pavilion 3 formed around the decorative surface 31, which is on the side of the crown 2 formed around the peeping surface 21. Reflects on the facet 22 and causes the interior of the gem to shine. As a result, the decorative surface 31 of the pavilion 3 visually recognized from the peeping surface 21 of the crown 2 appears to emerge in the brightness.

Description

  The present invention relates to a jewelry cutting structure including a crown formed in an upper stenosis, a pavilion formed in a lower stenosis, and a girdle positioned between the pavilion and the crown.

  As a cut structure of jewelry, a facet cut and a cabochon cut are known.

  The cabochon cut is a cut that polishes the upper part of the stone into a dome-shaped curve and makes use of the gloss and pattern of the stone itself, not the reflection of light, mainly translucent stones, opaque stones, low-refractive stones, etc. Used for stones that are difficult to shine from the inside. Cabochon means nails in French.

  Faceted cuts, on the other hand, are mainly used for transparent stones (including colored transparent stones), and are formed by connecting a number of faces (facets) with different angles on the surface of the stone, so This is a cut that is refracted and reflected to make the stone appear to shine from the inside. The shape and arrangement of each face (facet) to be cut is determined by considering the crystal, internal structure, physical properties, etc. of the stone, and emphasizes the luster of the stone surface and the brightness from the inside. Yes.

  The important point in facet cut is to use the reflection and refraction of light accurately. For this reason, as shown in FIG. 4, a facet-cut gemstone j is generally composed of a crown cr with a flat table t formed at the top and a pavilion p with a sharp culet cu formed at the bottom. And a girdle g positioned between the crown cr and the pavilion p, and the curette cu is positioned inside the table t as viewed from above. A plurality of facets fc are formed in a row except for the table t of the crown cr, and a plurality of facets fp are formed in a row on the pavilion p (see Patent Documents 1 to 3).

  According to such a cut structure (facet cut), the light that has entered the jewel from the table t of the crown cr is reflected by the plurality of facets fp having the cullet cu on the pavilion p side as vertices, and this is reflected on the crown cr side. Are reflected by the plurality of facets fc, and reflection is repeated between the pavilion facet fp and the crown side facet fc, so that a beautiful shine can be generated inside when viewed from the crown cr side.

  By the way, so far, the culet cu has been considered indispensable in order to reflect the light that has entered the jewel. That is, if there is no culet cu, the light that has entered the jewel from the table t penetrates straight without being reflected, and it is not possible to obtain brightness. For this reason, eliminating the culet cu has been a taboo in the past gemological concepts. However, in the cut structure having the culet cu, even if the shape and angle of the crown side facet fc and the pavilion side facet fp are devised, they do not appear as much as the conventional ones, and are not surprising and interesting. It was difficult.

  The purpose of the present invention, which was created in consideration of the above circumstances, is to cut jewelry that breaks the conventional concept and creates new aesthetic value by eliminating curettes, which can cause unexpectedness and interest. To provide a structure.

  The present invention, which was created to achieve the above object, is a jewelry cut structure comprising an upper constricted crown, a lower constricted pavilion, and a girdle located between the pavilion and the crown. In addition to forming a peeping surface at the top of the crown, a decorative surface that is visible through the peeping surface is formed below the pavilion so that it is smaller than the peeping surface, and a plurality of facets are formed around the peeping surface on the crown. A jewelry cut structure characterized in that a plurality of facets are formed by surrounding a decorative surface on a pavilion.

  Moreover, it is preferable that the cutting | disconnection structure of the jewelry of this invention has the same outline shape of each of the above-mentioned viewing surface, a decoration surface, and a girdle.

  In the jewelry cutting structure of the present invention, the contour shape described above is a heart shape, the peeking surface and the decorative surface are parallel, and the decorative surface is included in the peeping surface as viewed from the direction orthogonal to the peeping surface. It is preferable.

  According to the jewelry cut structure according to the present invention, a peeping surface is formed on the top of the crown, and a decorative surface is formed on the lower portion of the pavilion so as to face the peeping surface. For this reason, when viewed from the crown side, the decorative surface of the pavilion can be visually recognized from the viewing surface of the crown.

  In addition, because the decoration surface of the pavilion is smaller than the viewing surface of the crown, the light entering the interior from the viewing surface is reflected on the facets on the side of the pavilion formed around the decoration surface, The light is reflected on a plurality of crown-side facets formed around the surface, and is repeatedly reflected between the pavilion-side facets and the crown-side facets, thereby causing the interior to shine. As a result, the decorative surface of the pavilion viewed from the peeping surface of the crown appears to be raised in the shine.

  In this way, according to the jewelry cut structure according to the present invention, it is possible to break the conventional concept, create a new aesthetic value by eliminating the curette from the lower part of the pavilion, and cause unexpectedness and interest. it can.
