Artificial treatment of dyed purple jadeite type and its identification
Emerald, as its name implies, red is Fei, green is Tsui, is a kind of beautiful jade that came to China from Myanmar into green. However, in addition to green and red emerald, there are purple, white, black and other colors, is a typical multi-color jade species. One of its elegant purple and with a little hazy mystery unique, occupies an important place, popular with people purple, also known as violets, because of the similar toon tree Chunhua color, also known as Chun color. According to the different colors of purple and shades of color, purple emerald can be divided into two kinds: 1) Purple Purple Jadeite: lavender fresh and elegant, with a pink tone. Pink purple emerald crystal particles are often coarse, cotton and more to beans as much water is better less; 2) Eggplant Jadeite: darker, darker, with a purple blue emerald. Emerald purple emerald elegant deep, more uniform color, delicate crystals, and more waxy to appear Although the color of purple emerald favorite, but most of the larger crystalline purple emerald mineral particles, coarse texture, poor variety, short head, quality Bad, so in the jade jade stone wool industry is also circulating the 'ten-pound nine collapse' jargon, that is cut after the emerald cut if found to be purple, gambling stone in nine out of nine bet. It is because of the relatively good quality purple emerald output is relatively small, so artificial dyeing purple emerald is often flooded the market, shoddy, I recently found in the jade market a large number of stained purple emerald Wool and finished products, a little inattentive, people will be deceived one, artificial dyeing purple emerald type
The more common on the market of artificial dyeing purple emerald mainly has the following types:
1 surface directly stained purple emerald. The use of purple dye on the surface of jade products smear, so that the dye attached to the cracks in the surface and mineral particles in the gap, resulting in a faint purple emerald. Such dyed jade mainly appeared in some jade wool semi-finished products and bracelets products (Figure 1) Figure 1 directly dyed purple jade bracelets
2, fried dyed purple emerald. The jadeite product to be processed is firstly heated and then rapidly soaked in the liquid purple dye. Due to the effect of thermal expansion and contraction, more small cracks appear on the surface of the jadeite and the dyes penetrate inwardly along the fracture to cause emerald dyeing. This type of stained emerald mainly found in some jade bracelets products (Figure 2) Figure 2 explosion-stained purple jade bracelet
3B + C goods purple emerald. The use of crystal rough, dry, dark impurities, the general quality of white jade, soaked by strong acid treatment, out of impurities, and then use purple dye staining, and finally vacuum injection plastic processing jade products (Figure 3) Figure 3 B + C Purple emerald
Second, artificial staining purple emerald identification features
1. Surface directly dyed purple emerald. Since only the surface is slightly dyed, the internal structure of the emerald is not damaged, and some features replica love cartier ring of the natural emerald are still retained. For example, the surface is smooth and bright, with a glassy luster. The orange peel pattern is visible and the striking sound crispness is very confused in the market Sex. But can be identified by the following features:
1) macro observation, uniform color distribution, can not see the color of the root, the different color boundaries is not obvious, for the transitional state (Figure 4). However, the natural purple emerald crystals are often relatively coarse particles, purple jadeite minerals will form a granular particles appear, the purple color is issued by the particles inside, uneven distribution, with the thickness of the color depth varies, the color boundaries tend to be more obvious (Figure 5) Figure 5 natural purple emerald particles clear, well-defined
2) the color distribution in the surface, the dye was silk-like, dotted distribution (Figure 6). Because it is directly on the surface of the dye, the dye is mainly attached to the surface of the jadeite products, the light purple dye was distributed in the surface of the mineral particles in the mesh gap and small cracks; with a magnifying glass, you can see some pits attached to the pits Purple dye (Figure 7);
Figure 7 dye was dotted distribution
2. Explosion stained purple emerald. The main identification features are:
1) rough surface, gloss is not strong, reticular fissures obvious. Due to the heating and soaking fake cartier ring mens dye dilation and contraction of the role, resulting in emerald surface observed in the reflective surface, appear to be relatively rough, does not reflect the bright natural glitter characteristics of glass luster, and the apparent dense grid-like shrinkage cracks (Figure 8) imitation cartier ring mens Figure 8 Deep-purple stained purple jade bracelet surface grid-like cracks
2) The dye is enriched in the network cracks. Zoom in observation, the purple dye is mainly concentrated in the grid-like cracks;
3) Percussion sound boring. Due to the more small fissures produced by the cartier ring mens replica fissure, the emerald loose structure, percussion sound is not so crisp emerald natural, but more dull 3B + C goods jade. Such jade products because it is acid etching, dyeing and then injection, making the dye can not only deep into the depths of jade, while after the injection of plastic, the original will be concentrated in the cracks or gaps in the dye diluted and tend to be uniform One of the more common emerald B + C purple jadeite products is one that is similar to the natural purple emerald. The main distinguishing features are:
1) The surface has obvious acid corrosion pattern. Magnified observation showed spider-reticulate acid-etched lines on the surface (Figure 9). Natural emerald mainly showed smooth embossed and depressed orange striae (Figure 10).

2) color divergence, colorless roots. The color is more uniform, divergent, dull, the transitional boundary between the purple zone and other colors is not obvious, gradually transitioned through the light, the color of the light divergence, colorless roots (Figure 11);
Figure 11 B + C emerald color divergence, colorless roots
3) Luster is not strong, transparency is muddy, foggy. After B + C treatment, emerald is often the overall appearance of white, foggy, luster is not strong, reflecting the characteristics of oil luster; rather than natural jade as bright and transparent, clear and mellow;About cartier necklace gold juste un clou copy Latest vogue
