the emerald cufflinks by many small mineral particles

I remember during the Guardian company, often guests talking about the collection of categories, if painting the identification of more subjective factors, then the identification of the jade jewelry cufflinks relies entirely on the objective criteria. An emerald cufflinks sent to identification, to go through these procedures, in order to reach a final conclusion: clones to the naked eye the appearance of the emerald cufflinks, look at its color, transparency, shape, appearance and gloss. It is an effective means of expression in the cufflinks aesthetics. The luster of the emerald cufflinks glass luster, some emerald cufflinks appearance is waxy luster, is suspected of B jade cufflinks. The determination of the refractive index refractometer.
The refractive index is the gem of the very important optical properties of different stones have different refractive index measure accurately the refractive index can conclude that this is what gem. Emerald cufflinks of the refractive index of 1.66, looks similar emerald cufflinks green nephrite refractive index of 1.61 to 1.63, while posing as the emerald cufflinks of quartz jade refractive index of 1.54. In the color, the cufflinkscan use contrast as well as in the composition of lines in order to obtain aesthetic results. With a microscope to observe the emerald cufflinks internal structure. Emerald cufflinks structure is granular mosaic change the crystal structure, which is a term of geology, that the emerald cufflinks by many small mineral particles, these small mineral particles, granular, fibrous, long columns and short columnar, as each other mosaic arrangement.
Connoisseur of such a structure called the "Green" is an important basis of the line of household gross identification, many people call it "flies wings. Under the microscope to observe the B jade cuff links, can see the emerald cufflinks structure has been damaged, loose structure, in small mineral granule is also filled with resin. For example, when in clothing of simple color and concise style, in the selection of jewelry, you can use bright cufflinks. With the spectroscopic determination of the absorption spectrum of the emerald cufflinks. Spectroscope can measure the degree of light absorption of the precious stones of various wavelengths of different Bao Shi Duiguang have different absorption characteristics of green jade cufflinks on a wavelength of 489 ~ 503nm, 690 ~ 710nm light absorption, the two absorption spectra is emerald cufflinks light absorption characteristics.
