Abstract
The invention relates to a moissanite gem with bright carving surface and cutting and grinding processing methods of the moissanite gem. For the moissanite gem, the crown angle is 34-35 degrees, the pavilion angle is 41-42 degrees, the table width is 49%-51%, the crown height is 17%-18%, the pavilion depth is 43%-44%, and the total depth is 62%-65%. The methods comprise cutting and grinding angle and proportions of various common bright cutting types of moissanite gems. According to specific properties of crystal axis orientation, refractive index, color, color, transparency and the like of the moissanite gems, after the cutting and grinding angles and proportions are adopted, comprehensive and optimized gloss, flicking and color of the curved-surface moissanite gems are displayed.
Description
Technical field
The present invention relates to a kind of mill method of cutting of moissanite jewel, relate in particular to the bright cut moissanite jewel of facet and cut the mill processing method.
Background of invention
Rareness due to natural gemstone, craftsman are for the volume of large as far as possible reservation jewel, often jewel is cut into substantially convexity or various irregular shape, even glossing is fabulous like this, the gloss of jewel, flicker and fiery color texts can not obtain best representing.Since at the beginning of last century, along with the change of people's consumption view, the aesthetic property of jewel more and more comes into one's own.By following the optical laws of crystal, set angle and the ratio of cutting mill, can make the brightness of jewel and fiery coloured silk reach best fully.1919, Marcel Tolkowsky has delivered famous " Diamond Design " book, based on the refractive index of diamond, and has considered brightness and the color effect of fire, and what calculated circular bright type diamond cuts angle lap degree and ratio.But the computational process of Tolkowsky has been missed the light of some part, and its result has error.
The moissanite jewel also claims mulberry to bore, and formal name used at school carborundum is a kind of synthetic gem, and it has than diamond (the diamond refractive index is about 2.42) high refractive index and be only second to the hardness of diamond also, so be the artificial diamond material of the best at present.The colored moissanite monocrystalline that the growing method that provides of Chinese patent file CN 101037806A and Chinese patent CN 128770C can obtain, color gamut comprises green, yellow, blueness, black and closely colourless, and the moissanite monocrystalline color homogeneous that obtains on the basis of this technology, the transparency is good.CN102198701A provides a kind of processing method of facet moissanite jewel finished product.Comprise the steps such as cutting, pre-type, cast, grinding, polishing, with the diamond cutting secant, the moissanite monocrystal rod is cut into little cuboid crude green body, be not more than the face of 5 ° as table top with the c face of moissanite cuboid crude green body or with c face drift angle, thin outer thick abrasive disk in adopting, first grind with the abrasive disk inner ring again with abrasive disk outer ring grinding during grinding, polishing divides rough polishing and finishing polish, and strictly controls the process conditions of each step.The applicant quotes this patent application prospectus full content technology as a setting.
But all the time, the mill of cutting of moissanite jewel is all that cut proportion according to diamond carries out, and the moissanite jewel finished product that obtains often is inferior to diamond on brightness and fiery coloured silk.Moissanite (SiC) is silicon atom and carbon atom in the ratio of 1: 1 in conjunction with a kind of covalent compound that forms.Moissanite is aeolotropic crystal, belong to a positive photosensitiveness crystal of axle, its optical axis is parallel to the crystal axis (being the C axle) of crystal, and its birefringence is 0.043, so the refractive index of the different crystal faces of this material is different, this point has caused difficulty for the best cut proportion that accurately calculates the moissanite jewel.On the other hand, moissanite has multiple crystal habit, and it is many types of that academia is referred to as moissanite, and different crystal habits also has different refractive indexes.Many types of 6H-SiC, 4H-SiC and the 15R-SiC of comprising of modal moissanite, its C face refractive index is also different.As can be known, the refractive index of moissanite jewel is 2.65～2.69 according to He Xuemei " growth of a synthesizing silicon carbide and discriminating " literary composition (" jewelry science and technology " the 11st the 2nd phase of volume in 1999).On this basis, what the present invention had designed moissanite gemstone facet cut cuts angle lap degree and processing ratio, mainly comprise Guan Jiao, booth angle, the wide ratio of platform, crown height ratio, booth deeply than etc.
Summary of the invention
For the deficiencies in the prior art, the invention provides the bright cut moissanite jewel of a kind of facet and cut the mill processing method.
The term explanation:
Moissanite C face refers to the face perpendicular to the C axle.
The cut of jewel refers to the moulding of jewel, is the style that the former stone of jewel presents after pondering, also claims jewel cut or style.
Facet cut (brilliant cut) jewel that becomes clear mainly is divided into bizet, girdle and booth section three parts.Bizet is prism-frustum-shaped more than girdle, be the face of mainly viewing and admiring, and booth section is pyramid-shaped below girdle, can be used for inlaying.Table top refers to a plane of bizet maximum, also referred to as desktop, end face.As shown in Figure 1.
The facet cut jewel that becomes clear comprises the standard circular multiple concrete stone cuts such as cut, single bright cut, old single bright cut, two bright cut, Switzerland's cut, classic European cut that become clear.
The bright type jewel of facet cut angle lap degree and ratio: the waistline diameter of setting the girdle place is unit 1, mainly comprises with lower angle and ratio:
Guan Jiao: the horizontal plane angle of bizet interarea and waistline is Guan Jiao, is the reference angle of each face of bizet;
The booth angle: the angle of booth section's interarea and waistline horizontal plane is the booth angle, is the reference angle of each face of booth section;
The wide ratio of platform: mesa diameter or regular polygon diagonal are the wide ratio of platform with the ratio of waistline diameter;
The crown height ratio: the bizet height is the crown height ratio with the ratio of waistline diameter;
Booth deeply than: the height of booth section and the ratio of waistline diameter be booth deeply than.
Complete dark ratio: the ratio of total height and waistline diameter be entirely dark than.
The bright cut of modal facet is the bright type of standard circular.The bright type stone cuts of standard circular as shown in Figure 2, bizet is made of table top 11, hat interarea 13, star facet 12 and upper central plane 14, booth section is comprised of booth interarea 16 and lower waist facet 16, sometimes also has bottom surface 17.For the bright cut jewel of standard circular, except the basis of the bright cut of above-mentioned facet cut angle lap degree and ratio (Guan Jiao, booth angle, the wide ratio of platform, crown height ratio, booth deeply than, complete deeply than), upward central plane angle, star facet angle, lower central plane angle in addition:
Upper central plane angle: the angle of central plane and waistline horizontal plane on bizet;
Star facet angle: the angle of bizet star facet and waistline horizontal plane;
Lower central plane angle: the angle of booth subordinate central plane and waistline horizontal plane.
According to traditional processing technology, the angle of bizet star facet and waistline horizontal plane is less 5 ° than the hat angle, large 1～2 ° of the ratio Guan Jiao of central plane angle on bizet.Than booth angle large 1～2 ° of booth subordinate central plane angle.
Technical scheme of the present invention is as follows:
A kind of facet cut moissanite jewel that becomes clear comprises bizet, girdle and booth section three parts; Bizet is prism-frustum-shaped more than girdle, be the face of mainly viewing and admiring, and booth section is pyramid-shaped below girdle, is used for inlaying; The plane of bizet maximum is table top; Guan Jiao is 34 °～35 °, and the booth angle is 41 °～42 °, and the wide ratio of platform is 49%～51%, and the crown height ratio is 17%～18%, and booth is dark in being 43%～44%, and is complete dark in being 62%～65%.
