A kind of heart-shaped image diamond of round cut with 73 tangent planes
Technical field
The present invention relates to diamond technical field, be specifically related to a kind of heart-shaped image diamond of round cut with 73 tangent planes.
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 a kind of heart-shaped image diamond of round cut with 73 tangent planes, 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:
There is the heart-shaped image diamond of round cut of 73 tangent planes, be made up of bizet, waistline, three, booth portion part, have 73 tangent planes; 73 described tangent planes are made up of with 40 tangent planes being located at booth portion 33 tangent planes being located at bizet; 40 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, and 8 booth portion tangent planes that polishing from connecting line to vertex (vertices) is formed are formed the reflection of heart-shaped shadow.
Described kite face is quadrangle tangent plane.
Described star face and upper central plane are gore.
Described 40 tangent planes comprise 16 central planes, 16 the first booth portion tangent planes, 8 the second booth portion tangent planes, and the boundary line of 16 central planes and 16 the first booth portion tangent planes forms heart-shaped connecting line jointly, and 8 the second booth portion tangent planes are formed the reflection of heart-shaped shadow.
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 with 73 tangent planes of the present invention, make diamond have 73 tangent planes, improve diamond fire color, the unconventional cutting of vertex (vertices) part, produces heart-shaped effect of shadow, improves sight.Generation can be directly visual effect of shadow, improve the degree of glittering of diamond simultaneously with more tangent plane, give product more added value, 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, this has the heart-shaped image diamond of round cut of 73 tangent planes, and 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 lower central planes, 5,16 the first booth portion tangent planes 6,8 the second booth portion tangent planes 7, altogether 40 tangent planes; Tangent plane adds up to 73 tangent planes.16 the first booth portion tangent planes 6 and 16 proportional numerical value places that lower central plane 6 is designing join, viewed from top view, its handing-over line forms special heart-shaped connecting line, 8 the second booth portion tangent planes 7 that polishing is formed from connecting line to vertex (vertices) form the reflection of heart-shaped shadow, as shown in Figure 4.
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, blue flame cut improves technology difficulty, controls 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.
Join with the proportional numerical value place that lower central plane is designing, viewed from top view, its boundary line forms special heart-shaped connecting line, and the booth portion tangent plane that polishing is formed from connecting line to vertex (vertices) forms the reflection of heart-shaped shadow.This is for originally having more symbolic meaning with regard to the diamond that carry love meaning.Although such requirement adds a small amount of cost and difficulty of processing, bring more bright fire coloured silk.
