A kind of circle cut heart image diamond
Technical field
The present invention relates to diamond technical field, be specifically related to a kind of circle cut heart image diamond.
Background technology
Existing diamond is generally 57 tangent planes, mainly include bizet (CROWN): 1 desktop (TABLE), 8 star faces (STAR FACET), 8 kite faces (BEZEL FACET) go up central planes (UPPER GIRDLE FACET) with 16,33 tangent plane waistlines (GIRDLE) altogether: the position that diamond is the widest, also it is the intersection in bizet and beneath booth portion above segmentation diamond, during one's waist measures Jewel inlaying, is used for fixing the place of diamond.Booth portion (PAVILION) diamond below portion is referred to as booth portion, namely to the part of diamond tip below waistline.Including 16 central planes (LOWER GIRDLE FACET), 8 booth portion tangent planes (PAVILION FACET) point lowermost with 1 bottom surface (CULET), 25 tangent planes altogether;Because diamond might not have sharp bottom surface, so the diamond booth portion without point bottom surface only has 24 tangent planes, tangent plane sum is 57 tangent planes.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, the present invention proposes a kind of circle cut heart image diamond, makes diamond have 89 tangent planes, is more beneficial for improving the degree of glittering of diamond.
Technical scheme: in order to realize foregoing invention purpose, the technical solution used in the present invention is:
A kind of circle cut heart image diamond, is made up of bizet, waistline, three, booth portion part;89 described tangent planes are made up of 33 tangent planes being located at bizet and 56 tangent planes being located at booth portion;56 described tangent planes include that lower central plane and booth portion tangent plane, lower central plane form heart-shaped connecting line with the boundary line of booth portion tangent plane, from being connected to formation heart-shaped shadow reflection on the booth portion tangent plane that vertex (vertices) polishing is formed.
33 described tangent planes include 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 include 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 is collectively forming heart-shaped connecting line.
The wide ratio of platform is positioned between 55% ~ 65%.
Crown height ratio is positioned between 57% ~ 68.5%.
Waist thickness controls between 2% ~ 4.5%.
Guan Jiao is between 34 ° ~ 37 °.
Booth angle is between 39 ° ~ 43 °.
Beneficial effect: compared with prior art, the round cut heart image diamond of the present invention, make diamond have 89 tangent planes, be more beneficial for improving the degree of glittering of diamond.The heart-shaped shadow reflection that bottom particular design is formed, become the special marking of diamond, improve diamond fire color, vertex (vertices) part is cut and is produced heart-shaped effect of shadow, improves sight, the effect of shadow that generation can be the most visual, improve the degree of glittering of diamond with more tangent plane simultaneously, giving the more added value of product, increase enterprise core competence, outside imitation difficulty 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, this circle cut heart image diamond, it is mainly made up of bizet, waistline, three, booth portion part;Bizet includes 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 of the 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 includes 16 first time central planes 5,32 second time central planes 6,8 booth portion tangent planes 7, altogether 56 tangent planes;Tangent plane sum is 89 tangent planes.In terms of top view, the connecting line of 32 second time central planes 6 and 8 booth portion tangent planes 7 is collectively forming heart-shaped connecting line, forms heart-shaped shadow reflection on the booth portion tangent plane 7 that polishing from connecting line to vertex (vertices) is formed.
In order to ensure excellent fiery color effect, this diamond is positioned at wide for platform ratio between 55% ~ 65%, and crown height ratio is positioned between 57% ~ 68.5%;For higher cost performance, waist thickness is controlled between 2% ~ 4.5%, controlled by the location of Guan Jiao and the location at booth angle simultaneously, control in optimum state by the refraction of light, i.e. 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 color.
The outline line formed by the boundary line of booth portion tangent plane with lower central plane tangent plane, is rendered as heart, as shown in Figure 4.This is for originally just carry the diamond more symbolic meaning of love meaning.
