What is optimization? What is processing? How to identify and optimize the gemstones? Has the value of optimized and treated gemstones increased or decreased? Jewelry also has micro-shaping, and 4 questions teach you to understand optimization and processing.
What is optimization?
Optimization is a relatively traditional "micro-shaping" method and one of the most widely accepted. Optimization refers to various ways to improve the potential beauty of a gemstone. Common optimization methods include heat treatment of all gemstones except jadeite, bleaching of all gemstones except jade, waxing of all gemstones except turquoise, impregnation of colorless oil, staining of chalcedony and agate gemstones. Why in addition to jade, because the red and yellow heat treatment of jade is the optimization of jade.
Optimization has no effect on the essence of jewellery and jade, and does not change its original nature. Therefore, the name of the gemstone is directly used in the naming, and the gem identification certificate may not be described in the certificate, that is to say, the “optimization†may not be indicated in the gem identification certificate, so care about this. Point friends should consult with the merchant before buying.
What is processing?
Compared to optimization, processing refers to non-traditional and less acceptable methods of improvement. Common treatment methods include dip color oil, filling (filling of hard materials such as glass filling, plastic filling or other polymers), dyeing, irradiation, laser drilling, film coating, diffusion, high temperature and high pressure treatment, and the like. Such as jade dyeing treatment, diamond irradiation treatment, sapphire surface diffusion treatment, ruby ​​glass filling treatment.
These treatment methods have a fundamental impact on the color and texture of jewellery and jade. Therefore, the national standard stipulates that the treated jewels should be marked with the word "handling" or indicate the treatment method after the name of the jewellery and jade. Such as sapphire (diffusion) or sapphire (treatment); can also describe specific treatment methods, such as diffusion sapphire, before the name of the corresponding jewelry jade.
How to identify and optimize the gemstones?
Some of the optimized treatments are very delicate and can hardly be distinguished from natural products. For example, imitating natural heat treatments and irradiated treatments, the most obvious example is that the irradiated blue topaz is stable and beautiful, and it is almost impossible to identify. There are also some optimized treatments that are very fine, but they still show flaws under the professional jewellery and jade identification instruments. Regarding optimization and processing, we can also treat it separately. The optimized gemstone will make its color more full and more beautiful. It only does not destroy the inner part of the gem through physical methods. If you don't care about the natural thing, you can only pursue the ultimate color of jewelry. consider.
Has the value of optimized and treated gemstones increased or decreased?
The preciousness of jewellery and jade is rare, and natural gems are of course more valuable. However, the current global gemstone mining has made the amount of natural gemstones less and less. Based on this, the “micro-shaping†of gemstones will be derived, so that more gemstones have the ultimate color. Compared to pure natural gemstones, the optimized and treated gemstones are worth a discount, but the optimized gemstones are worth more than natural gemstones. Therefore, the rise and fall of value cannot be generalized.
