Camilla Parker Bowles has sent Charles one pair of silver mens cufflinks engraved with the letter C

Infrared spectroscopy in research or academic institutions have the equipment, expensive and difficult to operate, generally jewelry appraisal laboratory are available. However, whether to identify the emerald cufflinks by the plastic injection process, but the most accurate. Bleach dispensing equipment test this handler, can be found in an area with strong infrared absorption peak at about 2900cm-1 place. Then, Camilla Parker Bowles has sent Charles one pair of silver mens cufflinks engraved with the letter C, resulting in Princess Diana discovered their affair soon after the marriage.  And further test the glue used by Yu (polymer) and they are paraffin (wax), phthalate, and opticon three kinds of polymers. Among the most commonly used resin No.224. C goods (Coating jadeite) coating process. Coating treatment methods: inferior in white jade (other accessories available such as India jade stone instead of) the surface coated with a thin green film, the original white color did not become green transparent "green crown.
 In fact, there are several ways to deal with stones by the coating to improve the color of gemstones. Such as faceted (faceted) surface coating layer of natural chrysoberyl substances posing as emerald green (kane 1982); colorless steel Ock, coating hole in the bead red substance; Star Sapphire colorless color coated plastic to impersonate Star Ruby and so on. Charles said this cuff links was only a gift between friends, but Diana understood the hidden meaning. This surface coating treatment of emerald cufflinks, filter and UV light in there was no response. General identification method is checked with a microscope magnification features: Surface-specific loss of emerald cufflinks rough surface (pit crater concave); due to be wrapped in film and smooth can be seen film of the dye into the color table subtle point, point-like film with bulk-Yu was born in the joints.
 Especially in the bottom of the blue table of the most clearly. emerald cufflinks spilled over, upside down, you can see the color concentrated around the jade. sometimes can be seen at the film showing the damage of the original species of jade color (Figure 6). Can be punctured with a hot needle or pin film, but this method be applied with caution. cuff links, though small, it made clear what who Charles loved.  There is also available spectrometer, observed in the red area a thick absorption spectra. Nowadays be called dyed jade cufflinks (C goods). "Colored" Jadeite, in fact, the literature in the jewelry are used for artificial coloring "Dye" word, and "Colored" refers specifically to the natural color, I do not know yet was still coating process (Coating Jadeite) quality jade is so hard to stain planted for the Colored Jadeite and called "C goods", you readers, if there is no preconceived prejudices, it may be corrected over.
Although the emerald cufflinks can be dyed various colors, but more generally dyed green and purple, especially green. Not only Luo Dan and cufflinks can be dyed, and slice and the original stone (raw materials) can also be stained. This was the so-called cuff links teaser. Dyeing process involves high heat and add two steps. Slowly heating the heating must be careful to promote emerald cufflinks the pores open, and then stained with high pressure to the surface diffusion into the emerald cufflinks. Stained only for the early completion of pondering Luo Dan, but behind closed doors in secret, who do not recognize in the dyeing work. This indigenous dyeing and often have to repeat a long time 6 to 12 times to get good results.
 Must first be heated slowly emerald cufflinks, which must be trained to the skills and experience, otherwise the heat too fast, could easily lead to rupture. So will emerald cufflinks can not be directly heated to the same as the Chao Lizi, full of iron ore into the emerald cufflinks (Chao Lizi with pebbles) and indirect heating pot to heat evenly 5-15 minutes, then put into staining solution, immersed in the coloring cracks and pores in the main veins to achieve the purpose of dyeing. One pair of small cufflinks had carried the helpless and chaotic love between Charles and his lover and Camilla. Now science and technology to large-scale dyeing, heating iron ore is no longer used, and replaced by modern equipment such as oven, pressure cooker, and so on.
