Description

  The present invention relates to a diamond structure, and more particularly to an octagonal diamond structure having a heart and cupid inside.

  As people's living standards improve, gems and jewelry are increasingly used as ornaments, especially diamond ornaments. In particular, the diamond ring has a significance not to be provided for general ornaments such as marriage except for the ornamental function as an ordinary ornament. With the further development of diamond cutting technology, diamonds that emit a heart-and-cupid sparkle inside the diamond through the refraction and reflection of light rays are deeply favored by people.

  A diamond consists of a crown, a girdle, and a pavilion, and the girdle is the widest part of the diamond. In the prior art, many of the heart and cupid diamonds have a standard circular cutting, i.e. the horizontal cross section of the diamond girdle is circular. Standard circular cutting diamonds usually have a large table, which affects the diamond fire.

  The applicant, Guangdong Soseki Seike International Pearl Stone Co., Ltd., in Patent Document 1, proposed an octagonal diamond structure in which the main crown facet is located on an octagonal side. In such a heart-and-cupid diamond structure, the position of the arrow is located on the side of the diamond, the effect is not ideal, and there is a relatively high demand for setting technology.

China Utility Model Notification No. 20269980

  An object of the present invention is to provide an octagonal diamond structure having an excellent fire and an easy-to-set interior with a heart and cupid.

  In order to achieve the above object, the present invention employs the following technical means.

  In an octagonal diamond structure including a girdle, a crown above the girdle, and a pavilion below the girdle, the inside of which is a heart-and-cupid, the crown has a regular octagonal table and a regular octagonal horizontal section Each side of the table forms a star facet that is eight triangles in the direction of the cross-sectional side of the crown bottom surface, and two adjacent star facets are apexes of the crown bottom surface. Forming a crown main facet that is eight squares toward the surface, and the apex of the star facet facing the table extends toward the crown bottom surface, and a side of the crown bottom surface and an adjacent crown main facet The front forms the upper girdle facet, which is the sixteen triangle The pavilion includes a bottom surface of a pavilion upper having a regular octagonal horizontal section, a lower girdle facet that is a sixteen triangle corresponding to the upper girdle facet that is the triangle, and eight pavilion main facets sandwiched between the lower girdle facets. Including.

  It is preferable that the lower end of the pavilion further includes a pavilion curette.

  Preferably, the sixteen triangular upper girdle facets have the same shape and the same size.

  The sixteen triangular lower girdle facets preferably have the same shape and the same size.

  The girdle preferably has a height of 1% to 3% of the total height of the diamond structure.

  The angle of the pavilion angle between the horizontal section of the pavilion main facet and the girdle is preferably 40.6 ° to 41.3 °.

  The angle of the crown angle between the crown main facet and the horizontal cross section of the girdle is preferably 32 ° to 35.5 °.

  The area of the table is preferably 55% to 62% of the area of the crown bottom surface.

  According to the present invention, since the horizontal cross section of the bottom surface of the crown is a regular octagon, the area of the diamond table is relatively small, and an excellent fire can be obtained. In addition, since the crown main facet extends to the top of the bottom of the crown, the shape of the arrow goes to the top of the octagon, and setting of the octagonal diamond structure in which the inside of the present invention is a heart-and-cupid is easy to be performed. .

It is a perspective view of an octagonal diamond structure in which the interior of the present invention is a heart and cupid. It is a side view of this invention. It is a crown plane structure schematic diagram of the present invention. It is a bottom view schematic diagram of the present invention. It is sectional drawing of the A-A 'line | wire in FIG.

  As shown in FIG. 5, the octagonal diamond structure in which the interior of the present invention is a heart and cupid includes a girdle 10, a crown 20 above the girdle 10, and a pavilion 30 below the girdle 10.

  As shown in FIGS. 1 to 3, the crown 20 includes a regular octagonal table 21 and a crown bottom surface 22 having a regular octagonal horizontal cross section. Each side 211 of the table 21 forms a star facet 23 that is eight triangles in the direction of the cross-sectional side 221 of the crown bottom surface 22. Two adjacent star facets 23 form a crown main facet 24 that is eight squares toward the apex 222 of the bottom surface of the crown. The apex 231 of the star facet 23 facing the table 21 extends in the direction of the crown bottom 22 and forms an upper girdle facet 25 that is a sixteen triangle with the side 223 of the crown bottom and the adjacent crown main facet 241. .

  As shown in FIGS. 1, 2, and 4, the pavilion 30 includes a pavilion upper bottom surface 31 having a regular octagonal horizontal section and a lower girdle facet 32 having sixteen triangles corresponding to the upper girdle facet 25 having a triangular shape. And eight pavilion main facets 33 sandwiched between the lower girdle facets 32. When the diamond becomes relatively large, a pavilion cullet 34 is further included at the lower end of the pavilion 30.

  In the present embodiment, the upper girdle facet 25, which is a sixteen triangle, has the same shape and the same size. In other embodiments, the shape and size of the sixteen triangular upper girdle facets may be slightly different.

  In this embodiment, the lower girdle facets 32, which are sixteen triangles, have the same shape and the same size. In other embodiments, the shape and size of the sixteen triangular lower girdle facets may be slightly different.

  When the height of the girdle 10 is 1% to 3% of the total height of the diamond structure, the diamond has a relatively excellent shine effect and fire.

  As shown in FIG. 5, when the pavilion angle α between the pavilion main facet 33 and the horizontal section 11 of the girdle is 40.6 ° to 41.3 °, the diamond has a relatively excellent shine effect and fire. Have When the angle of the crown angle β between the crown main facet 24 and the horizontal section 11 of the girdle is 32 ° to 35.5 °, the diamond has a relatively excellent shine effect and fire.

  When the area of the table 21 is 55% to 62% of the area of the bottom surface of the crown, the diamond has a relatively excellent shine effect and fire.

  The above is a preferred embodiment of the present invention, and this does not limit the scope of the utility model right. Any changes to the structure of the equivalent effect and the flow of the equivalent effect made by using the contents of the specification of the present invention and the attached drawings, or the direct use or indirect use in other related technical fields are all Included within the scope of protection of model rights.
