Description

Product with improved optical characteristics
Technical field
The present invention relates to a kind of by (undressed mistake) natural or artificial (part) diamond material, more particularly be natural or cutting products that rhinestone is made, comprising:
-have the bottom (jewel bottom (pavilion)) of bottom (culet (culet));
-have the top (bizet) on a plurality of facets and a top (table top is wide be 0 point or have the wide end face of table top (table top)); And
-girdle (girdle) between bottom and top.
It should be noted in the discussion above that in the situation that rhinestone, raw material (substrate) can be by any technical matters manufacture, such as chemical gaseous phase deposition (CVD) or HTHP technique (high pressure-temperature technique).One example of CVD technique is the technique that Apollo Diamonds Inc. (Apollo Diamond Inc.) uses.
Background technology
The cut of jewel is determined by its facet.These facets relative to each other have given shape, certain position and special angle position.Above-mentioned cut is determined in the combination of given shape, location and the angle position of different facets.The angle position of the different facets of cut is determined by the scale parameter of this cut.
The value of the diamond that has cut is determined by cut (Cut), cleanliness (Clarity), carat (Carat) and these four C of quality (Colour) on significance level.They are respectively cut, cleanliness, weight and the quality of the diamond that cut.
" cut " can be regarded as the meaning that stone is processed.The shape of the stone that cuts forms this part.Processing relates to the quality of cutting and the ratio of cutting form.Figure 1A schematically illustrates the stone of prior art.Its crucial part is correct proportions and the purification of having cut stone 20.Ratio can be regarded as the degree of depth 35, table top reflection, girdle 22 of height 34, bizet angle beta, the jewel bottom 25 of bizet 24 and the meaning of the ratio of stone overall depth.Purification can be regarded as the meaning of meticulous integral body processing.How regular is girdle? is culet heavy or light? does bizet 24 exist different on symmetry between 25 bottom jewel? each other whether facet meticulous connection? culet whether accurately is positioned at center or whether table top eccentric? all of these factors taken together is to glossy the having a direct impact in stone.With cleanliness, quality is opposite and opposite with wt part, cut is artificial.Due to perfect and may become top stone with the stone that bright type cutting form has the circular weight of high-quality of best colourity, therefore, cut is very large pricing factors in above-mentioned four C.But if stone cuts (ailhead) or excessively shallow (flake) deeply, the glossy of stone will pass, just and stone has lower value.In brief, processing is very important because it finally can bring stone most important in its radiance at all aspect: briliancy and color and luster.
" cleanliness " is the transparency of the light of cutting diamond.Stone can have inside and outside flaw.Internal flaw generally includes does not have complete crystallization or slot (glet) (internal fissure).They exist many multi-form, but also have different strength grades.The growth line represents the structure of former stone.They also have such as the external behavior such as palpus shape effect (bearding) that stays when too difficulty is cut at stone.It may be also natural residual when stone cuts too smallly.These characteristics can be seen in girdle.All these characteristics have been determined the cleanliness of stone, and it can be divided into different classes of: perfect, VVS1, VVS2, VS1, VS2, SI, heavy flaw 1 (Pique 1), heavy flaw 2, heavy flaw 3.By the well-trained eyes of diamond businessman or in laboratory, under microscope, carry out the assessment to cleanliness.
The weight of jewel (carat) represents (1 carat=0.2 gram) with carat.Carat is subdivided into 100 minutes, and is often expressed as 2 significant digits, for example 0.24 carat or 24 minutes.
Colourity is normally subjective.Colourity is whiter, and price is higher.Colourity is to determine according to one group of so-called standard stone (master stone).This is that it has different colourity under highest ranking by the different one group of stone that first-chair diamond businessman assessment obtains that is in, and this just is counted as standard.Assessment is generally carried out with eyes.Current electronics assessment is also feasible.
But in practice to the appraisal of cutting diamond than measure or definite 4C more complicated.Except the combination of different C, often to subjectively assess colourity, cleanliness and cut.In addition, the processing of stone and life-span also will be taken into account.The life-span of stone is the subjective measurement of diamond briliancy.Therefore the value of cutting diamond can not be determined according to 4C fully.In this article, with reference to colourity, briliancy, heat color (fire), flash of light (scintillation) and life-span as optical characteristics.
Traditional cut such as bright type cutting, pyriform cutting or oval cutting has specific shape, because these specific shapes produce the cutting diamond of " the most beautiful ".These assessments of cutting the best diamond that produces are based on to the original processing of Tolkowsky.Tolkowsky has developed modern bright type cutting in 1919.Above-mentioned bright type Tolkowsky cutting or the bright type cutting of Tolkowsky are be used to making the lifelike reference of stone.At stone, have beautiful briliancy, and then while having best optical characteristics, stone just had life.
Can explain the optical characteristics of cutting diamond with different physical effects, wherein, the most important thing is lip-deep total internal reflection and anaclasis.Because diamond has very high refractive index (2.42) and has very little critical angle, therefore, the total reflection of light can appear on many cutting surfaces.Light is only stayed on the cut surface that diamond seldom measures.In this article, cut birefringence and total internal reflection have extremely important impact.The path that Fig. 2 A-Fig. 2 C explanation incident light is followed.In the situation that jewel bottom level 35 excessive (referring to Figure 1B) or jewel bottom level too small (referring to Fig. 2 C), light can be overflowed, and desirable cutting (referring to Fig. 2 A) produces maximum internal reflection, does not have by this light to overflow and can obtain best optical characteristics.
It has been generally acknowledged that, Tolkowsky has realized the mathematical computations of the optical characteristics of first consideration diamond.Tolkowsky calculates " desirable " scale parameter of bright type cutting.In other words, scale parameter is the free degree of cutting.Table 1 is described the restriction of the different proportion parameter of each kind to the assessment of the optical characteristics of traditional diamond cutting.

The specific embodiment
As shown in Figure 2, diamond is usually to exist table top 1, girdle 2 and culet 3 as feature.Zone between table top and girdle is called as bizet 4.Zone between culet and girdle is called as jewel bottom 5.Bizet and jewel bottom are comprised of facet 10-13.
Facet between table top facet 1 and girdle 2 is called as bezel.In an illustrated embodiment, have six bezels, each bezel comprise with the oblique facet 10 of table top of table top 1 adjacency and with the oblique facet 11 of girdle of girdle 2 adjacency.Facet between culet 3 and girdle 2 is called as the jewel bottom.In an illustrated embodiment, have six jewels bottom: with six culet facets 13 of culet adjacency and with six girdle jewels bottom facets 12 of girdle adjacency.
In the embodiment of Fig. 2, can form two oblique angles at the jewel bottom side: girdle jewel bottom facet gradient α 1, this girdle jewel bottom facet gradient α 1 can compare with jewel bottom gradient, in order to define traditional stone; And culet facet gradient α 2, this culet facet gradient α 2 is the formed angle [alpha] 2 of culet facet and girdle.In addition, on the bezel side, have in the present embodiment two gradients: the oblique facet gradient of girdle β 1, the oblique facet gradient of this girdle β 1 is the oblique facet of girdle and the formed angle beta 1 of girdle; And the oblique facet gradient of table top β 2, the oblique facet gradient of this table top β 2 is the oblique facet of table top and the formed angle beta 2 of girdle.Fig. 3 explanation is in the probable value of the oblique facet gradient of the average culet α 2 between 27 to 33 degree and is in the probable value of the oblique facet gradient of the average girdle β 1 between 39 to 43 degree.And the variation between mean value is no more than 10% usually, preferably is no more than 5%, is no more than best 1%.
Fig. 3 explanation has the modification of table top, although have the modification of the point as top etc., also drops on protection scope of the present invention.As shown in Figure 3, the table top wide 31 of the percentage of integral body (on average) width 36 of use girdle 2 or fraction representation or size are preferably selected between 10% to 30%.As shown in Figure 3, the whole height 37 of the percentage of integral body (on average) width of use girdle or fraction representation is preferably selected between 75% to 85%.
Finally, as shown in Figure 3, the percentage of integral body (on average) width 36 of use girdle or the girdle width 32 of fraction representation are preferably selected between 2% to 10%.
Obviously, can without departing from the present invention, to embodiment described here, further process (cut that for example cuts by the conduct type that becomes clear).Three examples of stone after Fig. 6 A, Fig. 6 B and Fig. 6 C explanation processing are respectively that circular brill, inclined-plane bore and pear bur with respect to the circle that rotate the jewel bottom at this.
Fig. 6 A and Fig. 6 B illustrate have table top 102, the circle of girdle 103 and culet 104 bores, and has:
-eight oblique facets 126 of table top and eight oblique facets 125 of girdle;
-eight girdle jewel bottom facets 114 and eight culet facets 115.
In the modification of Fig. 6 B, the jewel bottom is with respect to warpage angle γ of inclined-plane warpage.Can consider that hereinafter the illustrated principle of Fig. 5 is further optimized this angle, in order to obtain bottom best possible reflection in top.
In the meticulous cutting course of work, starlike facet 123 and half facet 124 are arranged on bizet, on the jewel bottom, arrange four other facets 117,118 in all cases, although those skilled in the art are to be understood that, more or less facet can also be arranged.
Fig. 6 C illustrates the modification of pear shape, and wherein, corresponding facet indicates with the same tag that adds 1000.Preferably, can consider that hereinafter the illustrated principle of Fig. 5 is come again this piece stone to be optimized, in order to obtain bottom best possible reflection in top.
It will be apparent to those skilled in the art that girdle generally includes many skill facets, it is removed in Fig. 6 A, Fig. 6 B and Fig. 6 C, in order to avoid make accompanying drawing overlapping.
With traditional scale parameter (referring to table 1), compare, it is evident that, each scale parameter described here of the present invention differs from one another.More particularly, in definite embodiment of the present invention, table top is less than the desired table top of traditional cut, and whole height and girdle thickness are usually large than the desired whole height of traditional cut and girdle thickness.In possible embodiment of the present invention, the culet facet angle α 2 similarly jewel bottom angle (being generally 41 degree) than traditional is little, and the oblique facet gradient of girdle β 1 is usually large than traditional inclined-plane gradient (being generally 34 degree).
Although these parameters are different from traditional numerical value, preferred embodiment described here is still take improved optical signature as feature, and these improved optical signatures can be determined objectively by commercially available software application on market.
As shown in Figure 4, the value of the angle for culet facet and the oblique facet of girdle as above and the mesa dimensions middle body at least that more allows the diamond bottom pattern reflects on the oblique facet of main facet, girdle of bizet and table top.The middle body of the pattern M of bottom is reflected in the main facet 126 ', 126 on top " in.Can select enough little table top by the suitable angle that combination is used for the facet of the facet on top and bottom, make above-mentioned reflection be achieved.This pattern usually also can be at table top 102 ', 102 " and lower facet 125 ', 125 " in see.Usually can select enough little table top by culet facet gradient and the oblique facet gradient of girdle in conjunction with as mentioned in a preferred embodiment, make above-mentioned reflection be achieved.
According to flaw and the shape of former stone, can be optimized to obtain to culet facet gradient and the oblique facet gradient of girdle best possible glossy, so that sufficient briliancy to be provided, in other words, have optimized optical characteristics.Described cut more shows as larger volume, and result is to increase with the weight that carat represents, this provides advantage economically really.The additional volume that the cut that Fig. 7 A and Fig. 7 B signal explanation as employing are determined according to the present invention can obtain.C1 represents the profile that traditional circle is bored, and C2 represents the profile according to diamond cutting of the present invention.That beat shade is resulting volume Oe.Above-mentioned volume depends on the shape of former stone and flaw wherein certainly, but it will be appreciated by those skilled in the art that and can obtain increase considerable on volume with cut according to the present invention in the situation that nearly all.
The possible cut of the present embodiment is the light that is designed to institute's incident in the internal reflection diamond, so that the reflection on girdle maximizes.As this principle illustrated in fig. 5, can bring to the optimization of optical characteristics very large contribution.Suitable selection table top is wide with result angle [alpha] 2 is, the light L that is present on inclined-plane will be mainly derived from the light via girdle and culet facet reflection.In order in stone, to obtain this reflection, 24 degree that angle δ must be more required than diamond material are larger.The desired value of angle [alpha] 2 is to obtaining this effect particular importance.
The additional effect of determined cut of the present invention is not only to make the light optimization that exists on the table top side of diamond, also makes the light optimization that exists on the bottom surface side of diamond.In other words, about the assessment of optical characteristics, not only there is a preferably diamond orientation, but exist, a plurality ofly preferably for the orientation of diamond, select.This just allows diamond to use according to cut of the present invention, when keeping optimised optical properties, to place by different way.
Finally, Fig. 8 A-Fig. 8 D illustrates three modification again according to stone of the present invention top, and they are not construed as limiting, and only play merely the purpose of explanation.In the modification of Fig. 8 A-Fig. 8 C, by the table top 102,302,402 of less, formed.For these modification, the size of table top usually the stone integral diameter 1% to 40% between.In the modification of Fig. 8 A, by starlike facet 123, formed, in all cases, comprise two and half facets 124 and a facet 125 with the girdle adjacency.In the modification of Fig. 8 B, by the starlet shape facet 323 on each lateral margin of table top 302, formed.In the modification of Fig. 8 C set be starlike facet 423 and with the facet 425 of girdle adjacency.Fig. 8 D illustrates the modification of the top of stone in point 602 place's terminations.
Fig. 9 A-Fig. 9 D also illustrates a plurality of possible but the top view according to pear bur of the present invention or the upward views that are not construed as limiting.
Finally, Figure 10 A and Figure 10 B explanation are according to two favourable embodiment of the bottom of circular brill of the present invention and pear bur.Can what its type in office, use corresponding bottom in the diamond of any other shape or any other cut.
The bottom of Figure 10 A comprises eight girdle jewel bottom facets 1014, these eight girdle jewel bottom facets 1014 and eight culet facet 1015 adjacency.Can use continuously and further process as far as 1010 pairs of stones of half facet of culet 1004.
