The flame fusion synthetic ruby cufflinks can only see the curved arc of growth lines

In the UV light source, the light-emitting natural ruby cufflinks and flame fusion synthetic ruby cufflinks can be hair red fluorescence, however, the natural ruby cufflinks addition of Cr element, but also containing a small amount of Fe. Due to inhibition of Fe fluorescence, the fluorescent effect of the natural ruby cufflinks weaker than the flame fusion synthetic ruby cufflinks, most of the natural ruby cufflinks are inert under the X-ray, while the flame fusion synthetic ruby cufflinks can The red phosphorescence. In the midst of the most welcomed collections of America, this pair of cufflinksattract much attention. When the ruby cufflinks Charles filters observed, the flame fusion ruby cufflinks can be more obvious red.
 The absorption spectra of natural ruby cufflinks and flame fusion synthetic ruby cufflinks absorption spectra of the same, but the natural ruby cufflinks by the influence of the concentration of impurity elements contained in the strength of its absorption lines are often weak, there is a change even some absorption lines missing, while the flame fusion synthetic ruby cufflinks a higher content of Cr element in its growth process, so it can have a very clear and the strength of high Cr absorption spectrum. The cufflinks wearing by George Washington in his inauguration dress are the most attracting.
 Lines of growth curved growth lines is an important basis of the flame fusion synthetic ruby cufflinks different from the natural ruby cufflinks. Natural ruby cufflinks often developed around the z-axis of the straight growth bands and growth of different directions with the law intersect at an angle distribution. The flame fusion synthetic ruby cufflinks can only see the curved arc of growth lines. Curved growth lines are often very fine, uniformly development can also be the end of the tip-off phenomenon. The cufflinks are now housed in the Smithsonian Museum of American History.  Arc with weak color tone differences between when the tiny bubbles or residual additive particle along the lines of the growth gathered the bending characteristics of the growth line will be more clear (see Figure 3-1-172).
Synthetic products of the early characteristics of the growth line is obvious to the naked eye can see. With the improvement of the production process or heat treatment again, growth lines bending characteristics will become blurred. Observation of the growth line is the first application of the naked eye, the samples were placed on a piece of white paper or white container filled with water were observed. Such as using a microscope, it should be observed under low magnification eyepiece. In the 19th century, clothing manufacturers are no longer adhere to the traditional tuxedo and ritual cufflinks. Beginners often the gemstone cufflinks engraved on the surface of the polishing line would be mistaken as growth lines, polishing lines tend to be short and straight, they are confined in a moment face a different arrangement of the different facets polished line, while the curved growth lines across the boundaries of the facets, continuously into a direction of the overall gemstone cufflinks.
 The bubbles flame fusion synthetic ruby cufflinks Another major evaluation based on the bubble. Bubbles tend to be small, some small point, only visible at low magnification and high magnification before they see the bubbles. Bubble and ruby cufflinks refractive index values vary greatly, so the bubbles can be more pronounced contours. He began to apply the gold cufflinks to the more casual clothing, while the invention of new synthetic materials greatly reduce the cost of production. The bubble is spherical, change a few cases the formation of the tadpole shaped like bubbles. The production process is relatively stable, individual bubbles is small, a small number, only sporadically visible. While the surge in air bubbles when the instability in the production process, a large number of point-like bubble piles of gathered, banded, cloudy, diffuse throughout the sample (see Figure 3-1-173).
