73
The round cut heart image diamond of tangent plane
Technical field
The present invention relates to diamond technical field, be specifically related to a kind of round cut heart image diamond with 73 tangent planes.
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 round cut heart image diamond with 73 tangent planes, 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 round cut heart image diamond with 73 tangent planes, is made up of bizet, waistline, three, booth portion part, has 73 tangent planes;73 described tangent planes are made up of 33 tangent planes being located at bizet and 40 tangent planes being located at booth portion;40 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, form heart-shaped shadow reflection on 8 booth portion tangent planes that polishing from connecting line to vertex (vertices) is formed.
Described kite face is quadrangle tangent plane.
Described star face and upper central plane are gore.
Described 40 tangent planes include 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 is collectively forming heart-shaped connecting line, form heart-shaped shadow reflection on 8 the second booth portion tangent planes.
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 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, produce heart-shaped effect of shadow, improve sight.Generation can be the most visual effect of shadow, improve the degree of glittering of diamond simultaneously with more tangent plane, give the more added value of product, it is outside that to imitate difficulty 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 round cut heart image diamond of 73 tangent planes, and 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 lower central planes 5,16 the first booth portion tangent planes 6,8 second booth portion tangent planes 7, altogether 40 tangent planes;Tangent plane sum is 73 tangent planes.16 the first booth portion tangent planes 6 and 16 lower central planes 6 join at the proportional numerical value of design, and in terms of top view, its handing-over line forms special heart-shaped connecting line, and 8 the second booth portion tangent planes 7 that polishing is formed from connecting line to vertex (vertices) form heart-shaped shadow reflection, as shown in Figure 4.
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, blue flame cut improves technology difficulty, and 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.
Joining at the proportional numerical value of design with lower central plane, in terms of 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 heart-shaped shadow reflection.This is for originally just carry the diamond more symbolic meaning of love meaning.Although such requirement adds a small amount of cost and difficulty of processing, bring more bright fire color.
