The heart-shaped image diamond of a kind of circle cut
Technical field
The present invention relates to diamond technical field, be specifically related to the heart-shaped image diamond of a kind of circle cut.
Background technology
Existing diamond is generally 57 tangent planes, mainly comprise bizet (CROWN): 1 desktop (TABLE), 8 star faces (STAR FACET), 8 kite faces (BEZEL FACET) and 16 upper central planes (UPPER GIRDLE FACET), 33 tangent plane waistlines (GIRDLE) altogether: the position that diamond is the widest, also be the bizet above segmentation diamond and the intersection in beneath booth portion, during one's waist measures Jewel inlaying, be used for fixing the place of diamond.Part below booth portion (PAVILION) diamond is called booth portion, namely from the part to diamond tip below waistline.Comprise 16 central planes (LOWER GIRDLE FACET), 8 booth portion tangent planes (PAVILION FACET) and 1 lowermost sharp bottom surface (CULET), altogether 25 tangent planes; Because diamond might not have sharp bottom surface, so only have 24 tangent planes without the diamond booth portion of sharp bottom surface, tangent plane adds up to 57 tangent planes.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, the present invention proposes the heart-shaped image diamond of a kind of circle cut, makes diamond have 89 tangent planes, is more conducive to the degree of glittering improving diamond.
Technical scheme: in order to realize foregoing invention object, the technical solution used in the present invention is:
The heart-shaped image diamond of a kind of circle cut, is made up of bizet, waistline, three, booth portion part; 89 described tangent planes are made up of with 56 tangent planes being located at booth portion 33 tangent planes being located at bizet; 56 described tangent planes comprise lower central plane and booth portion tangent plane, and the boundary line of lower central plane and booth portion tangent plane forms heart-shaped connecting line, are forming the reflection of heart-shaped shadow from the booth portion tangent plane being connected to vertex (vertices) polishing formation.
33 described tangent planes comprise 1 octagon desktop, 8 star faces, 8 kite faces and 16 upper central planes.
Described kite face is quadrangle tangent plane.
Described star face and upper central plane are gore.
Described 36 tangent planes comprise 16 first time central planes, 32 second time central plane, 8 booth portion tangent planes, and the boundary line of 32 second time central planes and 8 booth portion tangent planes forms heart-shaped connecting line jointly.
The wide ratio of platform is positioned between 55% ~ 65%.
Crown height ratio is positioned between 57% ~ 68.5%.
Waist is thick to be controlled between 2% ~ 4.5%.
Guan Jiao is between 34 ° ~ 37 °.
Booth angle is between 39 ° ~ 43 °.
Beneficial effect: compared with prior art, the heart-shaped image diamond of round cut of the present invention, makes diamond have 89 tangent planes, is more conducive to the degree of glittering improving diamond.The heart-shaped shadow reflection that bottom particular design is formed, become the special marking of diamond, improve diamond fire color, the cutting of vertex (vertices) part produces heart-shaped effect of shadow, improves sight, the effect of shadow that generation can be directly visual, improve the degree of glittering of diamond with more tangent plane simultaneously, give product more added value, increase enterprise core competence, outside difficulty of imitating is high.

Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is further illustrated.
As shown in Figure 1, Figure 2 and Figure 3, the heart-shaped image diamond of this circle cut, it is primarily of bizet, waistline, three, booth portion part composition; Bizet comprises 1 desktop 1(octagon), 82,8, star face kite face 3(quadrangles) with 16 upper central plane 4(triangles), 33 tangent planes altogether.The position that one's waist measures diamond is the widest is also the intersection in bizet above segmentation diamond and beneath booth portion, is used for fixing the place of diamond during one's waist measures Jewel inlaying.Booth portion comprises 16 first time central planes, 5,32 second time central planes, 6,8 booth portion tangent planes 7,56 tangent planes altogether; Tangent plane adds up to 89 tangent planes.From top view, the connecting line of 32 second time central planes 6 and 8 booth portion tangent planes 7 forms heart-shaped connecting line jointly, and the booth portion tangent plane 7 that polishing from connecting line to vertex (vertices) is formed is formed the reflection of heart-shaped shadow.
In order to ensure the fiery color effect of excellence, this diamond is positioned at wide for platform ratio between 55% ~ 65%, and crown height ratio is positioned between 57% ~ 68.5%; In order to higher cost performance, control thick for waist between 2% ~ 4.5%, simultaneously by the location of Guan Jiao and the positioning control at booth angle, control in optimum state by the refraction of light, namely Guan Jiao is between 34 ° ~ 37 °, and booth angle is between 39 ° ~ 43 °.Although such requirement adds a small amount of cost and difficulty of processing, bring more bright fire coloured silk.
By the outline line that the boundary line of booth portion tangent plane and lower central plane tangent plane is formed, be rendered as heart, as shown in Figure 4.This is for originally having more symbolic meaning with regard to the diamond that carry love meaning.
