Ruby cufflinks have a lot of its internal cracks

Specific performance: of Mong Hsu ruby cufflinks red edge absorption spectrum, the maximum absorption peak at 420 nm, here wavelength corresponding to the color purple; another strength of the absorption peak at 550 nm and 570 nm corresponding colors were green and yellow-green; within the range of 420 to 470 nm, the absorption intensity, this band corresponds to the blue and green-blue region. All precious metal cufflinks are not likely to have scratches left.  In summary, ruby cufflinks edge absorption intensity corresponding to the color purple, green and blue. The other band color absorption, but the strength of small, ruby cufflinks showing the color is purple, blue, green complementary color mixing color, mainly red.
Ruby cufflinks purple core in MongHsu the visible spectrum, the strongest absorption peak at 430 nm and 560 nm, corresponding to the colors blue and green. Almost no absorption in the range of 400 to 420 nm, all through the corresponding color is purple. Zero absorption intensity at 650 nm, corresponding to the color part of the red. Platinum cufflinks is no exception. Beautiful cufflinks network to support distributed program.  Therefore, this part of the absorption of the strongest blue and green, the majority of purple and some red through, so the actual color is reddish purple. Ruby cufflinks ribbon development throughout the absorption spectrum will vary, but the core part of almost purple to blue-violet gemstone cufflinks thick, it reveals an opaque black purple.
Ruby cufflinks, hard texture, hardness under the diamond. Its bright red color, cool, can be called a "red gemstone cufflinks highest. The magnificent, luxurious ruby gemstone cufflinks king, is a treasure of its advantages over all the gems cufflinks. Some old books that ruby cuff links are the most precious of God created everything, created by 12 kinds of precious stones cufflinks. Cufflinks ruby color was red, pink corundum, which is a kind of corundum, the main component is alumina (Al2O3), the red from chromium (Cr3 +). Only by the Cr color caused by the red corundum is called ruby cufflinks. Natural no chromium gemstone cufflinks blue sapphire cufflinks. Please note that as time goes by, there will be a natural oxide layer on the surface of platinum cufflinks.
 The main physical properties: refractive index: 1.762 ~ 1.770, bi-fold rate of 0.008 to 0.010; density: 4.00g/cm3; typical absorption lines; hardness of sapphire cufflinks side by side in the subsequent diamond, for the second large hardness 9, the surface of diamond can, in its depiction can easily use one of its edges in the surface of the glass to draw a line (the hardness of the glass is 6 or less); crack than the divergence, ruby cufflinks have a lot of its internal cracks, namely the so-called ruby cufflinks "10 Red 9 crack"; has a distinct dichroism, and sometimes the naked eye can see the color change from different angles; ruby cufflinks before processing prototype for the barrel, plate . Many people may prefer to have the cufflinks that has just been polished.
Crystal habit: the case of the trigonal system, complex tripartite body of partial aspects of crystal class; crystal form often has a barrel, short columnar, plate. The collection of mostly granular or dense block. Transparency: transparent to translucent. Luster: bright shiny glass to sub-adamantine luster. Refractive index: 0.008 ~ 0.010. Dispersion: low 0.018, pleochroism: dichroism manifests itself: purple / maroon, dark red / red, red / orange, rose red / pink light of: the U-(a-axis crystal negative light resistance). If this occurs, please send your platinum cufflinks to a qualified jewelry dealer.  Special optical effects: Star effect will be reflected in the light irradiation, a charming six-pointed star or twelve shooting stars, color effects, Mohs hardness: 9, SG (relative density) :3.99-4 .00 cleavage: no cleavage bottom parting development. Luminescence: ruby gold cufflinks in the long, red and dark red fluorescence under short wave ultraviolet radiation.
