Detailed description of the invention
Below embodiments of the present invention are specifically described.
It comprises the following steps: A, the wherein semipolish being cut into the diamond of two halves is placed on fixed position, exposes cut surface; B, use cathode-ray irradiate described cut surface and form cathodoluminescence figure phase, take this cathodoluminescence figure phase and make the first photograph; C, change the other half diamond after polishing, expose its cut surface, use cathode-ray to irradiate this cut surface and form cathodoluminescence figure phase, take this cathodoluminescence figure phase and make the second photograph and the second photograph and the profile shown by the first photograph are symmetrical arranged; D, the first photograph and the second photograph inserted corresponding in brill certificate.
What derive from same former stone has same cut surface to drilling tool, has basically identical mineralogical composition at its cut surface place, and it can form the extremely similar and cathodoluminescence figure phase of symmetry under cathode-ray irradiates.To a pair, figure is got to the cut surface bored luminous pattern formed under cathode-ray irradiates, thus obtain two a pair patterns to the same cut surface bored, this pattern is multicolour pattern, and is very similar symmetrical pattern, directly can embody this thus and derive from same former stone to brill.The multicolour pattern of above-mentioned symmetry is just equivalent to the complexion of this diamond, and this figure phase amplifies the photograph being made as photograph and being just equivalent to diamond.This photograph can configure separately, also can be inserted in diamond certificate.To fix brill and cathode-ray irradiation be carried out to it, amplify and compare with the photograph of diamond after getting figure and can differentiate the photograph of the whether corresponding diamond of this photograph, thus can differentiate that namely whether from same former stone, this is also a simple and easy approach differentiating diamond to boring whether a doomed couple.Two, to brill separately a period of time, as long as find the photograph of diamond namely to can be used for the another one diamond of the correspondence of comparison searching a doomed couple, can be found two diamonds of a doomed couple easily in many diamonds.
No matter mineral crystal grows under natural surroundings or artificial environment, the position of the difference of main component element, accessory element, trace element or the impurity element that all can attract because of each crystal face or attached work is different and different.When plane of crystal be subject to high-power electron beam (cathode-ray) irradiate time, different elements will send the light of different colours, different light and shade, and again because position angle is different, crystal face will show multicolour pattern.When a crystal is divided into two halves, the divisional plane of this two semi-crystal is subject to two cathodoluminescence figure phases that cathode-ray excites, two very similar figure phases that divisional plane can show as Mirror Symmetry because of the symmetry of its composition, structure, shape, position.Fig. 1 a and Fig. 1 b are the sampling figure of two cathodoluminescence figure phases of the cut surface that a pair couple of an embodiment bores, and Fig. 2 a and Fig. 2 b are the sampling figure of two cathodoluminescence figure phases of the cut surface that a pair couple of another embodiment bores.Whether the two pairs of pictures all show the born symmetry of figure phase and similitude to being drilled in divisional plane place, can determine boring whether a doomed couple according to this, from same former stone.When being sold to a pair lovers or man and wife with these two symmetrical crystal together with two symmetrical figure phases, there is splendid commemoration meaning.
More preferably, after step B, increase step B1, the position relationship between diamond and cathode-ray light source and incident angle are taken pictures or drawn, retain positioning relation figure; Step C1 is increased after step C, position relationship between diamond and cathode-ray light source and incident angle are taken pictures or drawn, retain positioning relation figure, thus accurate recording x-ray angle, easily to set the position relationship between diamond and cathode-ray light source at subsequent process, be convenient to again to make identical born in brill certificate, be also convenient to need to find the position relationship between diamond and cathode-ray light source to carry out fingerprint authentication when differentiating, improve determination rates.
