Brief description of the drawings
In the following description, accompanying drawing is aided with very clear comprehensively mode the present invention will be described, to implement this Invention, in the accompanying drawings:
- Fig. 1 illustrate in plan view the jewel according to an advantageous embodiment of the invention,
- Fig. 2 shows the jewel shown in Fig. 1 with upward view,
- and, Fig. 3 shows the jewel that Fig. 1 and Fig. 2 are explained with side view.
Embodiment
In being described below, refer to the attached drawing is using the term such as " under ", " on ", " top ", " bottom ", to help to understand.Must not It is understood as limitation of the scope of the invention.
Fig. 1 is manufactured since the diamond (implying that the similar pyramidal diamond with square bottom of general shape) that princess's formula is cut The jewel explained to Fig. 3.But, technical staff is easy to the specific jewel that will be described to other jewels or jasper progress Cutting.
In being described below, with reference first to the top of jewel, that is, during cameo incrustation in jewelry, it is normally present on Part jewel outside jewelry article.This is that observer can be with visible directly part jewel.
According to commonsense method, the top of jewel includes the gemstone table formed by flat facet and around table top and by multiple The bizet that adjacent facets are constituted.Bizet is substantially according to first direction H extensions (see Fig. 3).
By contrast, the jewel bottom oriented towards jewelry article is referred to as the booth portion of jewel.Booth portion is according to opposite with direction H Direction B extends, and is described hereinafter with reference to Fig. 2.
Fig. 1 shows the top view of the jewel according to the present invention, and therefore shows the top of jewel, and its general shape is It is generally square.
" waist " is jewel most wide part, provides its diameter:Therefore the waist 3 of jewel is generally square shown in each figure Shape, its four summit 1 (referred to here as lumbar apex) are connected with each other by four waist portion sides 2 of length identical.
As shown in Figure 1, in four waist portion sides 2 each be all circular arc (spill), its concave surface is towards outside jewel.
Fig. 3 illustrates the side 2 of waist 3 of jewel, is represented as illustrated with the dotted line between two lumbar apex 1 in Fig. 3 Waist 3.
There is octagonal table top 4 at the center on the jewel top shown in Fig. 1.Wherein four summits edge of octagonal table top 4 The diagonal D1 or D2 for waist aligns with lumbar apex 1, and forms table top angular vertex 5.Other summits of table top 4 and table top angle Summit 5 is alternate and constitutes waist facet summit 6.
The waist portion side length L of each side 2 of waist 3 is the beeline between two adjacent waist summits 1.
Waist facet summit 6 is equidistant with two adjacent waist summits 1 respectively.The position on selection waist facet summit 6 on online D4, The line D4 is perpendicular to the line D3 for connecting two lumbar apex 1, and the center C of the line segment through two lumbar apex 1 of connection. The distance between selection center C and waist facet summit 6 L1, so as to make its substantially the 18 to 22% of the length L of waist portion side 2.
In the example that Fig. 1 is explained, the distance between center C and waist facet summit 6 L1 are roughly equivalent to two waists The 20% of length L between summit 1.
Always according to the depth L2 of beeline L selection waist portion sides 2 concave surface between two lumbar apex 1 (see Fig. 1).
Depth L2 is roughly equivalent to the length L of waist portion side 2 5.5 to 9.5% (see Fig. 1).
The bizet 7 of jewel is (see the Fig. 1 and Fig. 3) formed between table top 4 and the side 2 of waist 2.
In the example that each figure is explained, bizet 7 includes four sides 8, equivalent to four tables for meeting the curvature of waist portion side 2 Face (see Fig. 3).
At four angles of table top 4, it is in substantially diamondoid four table top horn craving face 9 that bizet 7, which has, and one of summit is Formed by table top angular vertex 5, relative summit is formed by lumbar apex 1.Two other summit in table top horn craving face 9 exists Represented in Fig. 1 with T.
Bizet also includes four main facets 10, by the two of two adjacent waist summits 1 and two adjacent stations face angle facets 9 The facet defined between individual summit T is constituted, described two adjacent stations face angle facets 9 simultaneously quilt associated with adjacent lumbar apex 1 Take into account.
Main facet makes the plane P1 of winner's facet and the plane P2 formation α where table top 4 relative to the planar tilt of table top 4 Angle, angle α (being about 37 ° in the example that Fig. 3 is explained) between 35 to 39 °.
Bizet 7 further comprises four facets of referred to as waist facet 11, triangular in shape, between main facet and table top 4, Two summits 7 (as main facet 10) and waist facet summit 6 (as table top 4) are used as summit.
Finally, between four table top horn craving faces 9, table top 4 and waist facets 11, bizet has eight star facets 12, wherein Each star facet is triangular in shape, why so calls, and is because it is around the formation star of table top 4.
When cutting in this way, included according to jewel that is of the invention and showing in the various figures total with 24 quarters The bizet 7 in face.
With reference now to the jewel booth portion according to the present invention, with particular reference to Fig. 2.
Booth portion 13 extends between waist 3 and booth portion tip 14 that it is included.Because waist 3 is substantially square, Booth portion 13 is substantially in the pyramid with square bottom.
Booth portion 13 includes the booth portion star 15 with four arms, four arms connection booth portion tip 14 and each waist top Point 1.Star-shaped four arms in booth portion are referred to as " booth portion star facet 16 ".
Each arm has wider bottom 17 and forms the narrower tip of point 18, is thus connected lumbar apex.Four booth portions The wider bottom 17 of star facet 16 forms four abstract sides (being represented by dashed line) of square, and its center is defined by booth portion tip 14 (see Fig. 2).
In other words, near booth portion tip 14, booth portion star 15 has the bottom 19 of square-section.
According to a feature of the jewel of the present invention, the length of the diagonal 20 at bottom 19 for waist portion side length L 5 to 11%, preferably 5.5 to 10.5%.In this example, diagonal 20 is approximately equal to the length to the 8% of length L.
In addition to booth portion star 15, booth portion 13 has four booth portion waist facets 21 of adjacent side face 8.
Each booth portion waist facet 21 is formed by the flat facet with three sides:A line 22 is bending and and side The a line in face 8 is shared.Article 2 is 23 identical with 24 length while with Article 3, and Article 2 while and distinguish during Article 3 Lumbar apex 1 is connected to the point 25 on the line comprising diagonal 20.
25 position on the line comprising diagonal 20 of point is the plane P3 by the waist facet of booth portion relative to the plane of table top 4 What P2 orientation was determined:According to the present invention, substantially 60 ° of angle of inclination beta of the plane P3 relative to plane P2 (2 ° of plus-minus-see Fig. 3).
Three bottom booth portion facets 26 are set between booth portion waist facet 21 and booth portion star facet 16.
Each bottom booth portion facet 26 is triangular in shape, and its bottom 27 is included in the line containing diagonal 20, and two sides are the bottom of 27 are connected to lumbar apex 1.
Three bottom booth portion facets 26 are therefore with three bottoms 27 and point 25 alignd along the line comprising diagonal 20.Root According to the position of bottom booth portion facet 26, its a line can be shared or common with booth portion waist facet 21 with booth portion star facet 16 With, or if bottom booth portion facet 26 is between two other bottom booth portion facet 26, then without this common edge.
Amount to, booth portion 13 includes 24 bottom booth portion facets 26, on corresponding with the line containing diagonal 20 Axle each other axial symmetry image two bottom booth portion facets 26 share a bottom 27.
So implement, the booth portion of the jewel shown in each figure includes 32 facets, and the facet includes 24 Bottom booth portion facet 26, four booth portion waist facets 21 and four booth portion star facets 16.
The present invention is not limited only to just described special jewel.Moreover, the present invention is extended to including at least one institute above Any jewelry article of the jewel of description and displaying.
