Description

A kind of 66 face round bright type cut diamonds

Technical field

The utility model belongs to diamond cut technical field, is specifically related to a kind of 66 face round bright type cut diamond.

Background technology

The circular bright formula cut diamond in 57 faces is that diamond uses most cutting modes in the market.Standard is bright at present Lit cut diamond is made up of bizet, girdle and booth portion, with 57 facets.

In cutting, the angle, size, permutation and combination and occupied ratio to facet has strict requirements.But, If diamond is larger, 57 face cut of standard just occurs the not enough problem of flicker effect.So, the Rational Arrangement of diamond facet The light of diamond and fire coloured silk are all had a great impact with angle accuracy.

The facet of the facet and bizet that increase booth portion in the present invention forms correct cooperation, make diamond refraction more fully and Rationally, increase the dispersion of diamond, become apparent from fiery coloured silk, and make the flicker effect of diamond more preferable.

The content of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of facet arrangement more reasonable, angle The higher round bright type cut diamond of accuracy, specifically a kind of 66 face round bright type cut diamond, the utility model solve which The technical scheme that technical problem is adopted for：

A kind of 66 face round bright type cut diamonds, are made up of bizet, waist and three, booth portion part, the bizet top 1 octagon table top 1 is cut with, the octagon table top 1 is located at the centre on bizet top, around eight of table top 1 It is provided with 8 hat stars facet 2 on side altogether, between adjacent two hat stars facet 2, is provided with kite face 3, the kite face 3 there are 8, 16 upper central planes 4 are provided between kite face 3 and waist, and the booth portion includes the sharp bottom surface 6 of 16 lower central planes 5,1, in lower central plane 5 16 booth portion tangent planes 7 are provided between sharp bottom surface 6.

The further technical scheme of the utility model also includes：

The ratio of the width of the table top 1 and waist average diameter is 52% ~ 62%.

The complete deep ratio of the diamond is 57.5% ~ 63%.

The booth portion height is 41.5% ~ 45% with the ratio of waist average diameter.

The Guan Jiao of the bizet is 31.5 ° ~ 36.5 °.

The booth angle size in the booth portion is 40.4 ° ~ 41.8 °.

The ratio of the crown height and waist average diameter is 11% ~ 16%.

The ratio of the waist thickness and waist average diameter is 2% ~ 4.5%.

Compared with prior art, Advantageous Effects of the present utility model are：The utility model is by justifying in 57 face of standard Increase by 8 tangent planes on the basis of the bright formula cut 8 booth portion tangent planes of diamond of shape, make diamond that there is ideal symmetrical, through mathematics Calculate, change significantly the path of light, after light enters diamond, reflect from diamond mandrel, directly give out pearlescent Magnificent radiance.

Specific embodiment

Below in conjunction with accompanying drawing, specific embodiment of the present utility model is further described.

Fig. 1, Fig. 2 is referred to, the utility model 66 face round bright type cut diamonds of one kind, by bizet, waist and booth portion Three parts constitute, and bizet is provided with 33 facets, and booth portion is provided with 33 facets.Wherein, 33 bizet facets include bizet top The table top 1 of 1 octagon of cutting, the octagon table top 1 are located at the centre on bizet top, around eight of table top 1 It is provided with 8 hat stars facet 2 on side altogether, between adjacent two hat stars facet 2, is provided with kite face 3, kite face 3 also there are 8, in wind 16 upper central planes 4 are provided between zither face 3 and waist；33 booth portion facets include the sharp bottom surface 6 of 16 lower central planes 5,1, in lower waist 16 booth portion tangent planes 7 are provided between face 5 and sharp bottom surface 6.

With reference to Fig. 3, Fig. 4, the bizet of the circular bright formula cut diamond in 57 face of standard is by Centromedian just positioned at bizet top 1,8 hat 2,8 kite faces 3 of star facet of octagon table top and 16 upper central planes 4 are constituted；Booth portion then includes 16 lower central planes 5, 1 sharp bottom surface 6 and 8 booth portion tangent planes 7.

In the utility model, the ratio of the width of table top 1 and waist average diameter（That is platform width ratio）Preferably 52% ~ 62%, Complete deep than being 57.5% ~ 63%, the ratio of the booth portion highly with waist average diameter of diamond（I.e. booth compares deeply）For 41.5% ~ 45%, hat The Guan Jiao in portion is 31.5 ° ~ 36.5 °, and the booth angle size in booth portion is 40.4 ° ~ 41.8 °, the ratio of crown height and waist average diameter Example（That is crown height ratio）For 11% ~ 16%, the ratio of waist thickness and waist average diameter（That is waist thickness rate）For 2% ~ 4.5%.

Fig. 5 is referred to, 30 represent diamond blank in figure, 31 represent 66 face round bright type cut diamond of the utility model, 32 Represent the circular bright formula cut diamond in 57 face of standard；11 represent that light is entered inside the circular bright formula cut diamond in 57 face of standard Incident direction, 12 is exit direction；21 represent the incidence that light is entered inside 66 face round bright type cut diamond of the utility model Direction, 22,23 and 24 is exit direction.

Light into the circular bright formula cut diamond in 57 face of standard can be from diamond bottom or offside reflection out, so as to make Into light leak；As the utility model increased 8 on the basis of the circular bright formula cut 8 booth portion tangent planes of diamond in 57 face of standard Tangent plane, the utility model booth portion tangent plane are 16, and arrangement more reasonable, the angle accuracy of facet is higher so that diamond has Ideal symmetrical, through mathematical computations, changes the path of light significantly, and light will be refracted to from diamond bottom into after diamond Table top 1, so that give out dazzling radiance.
