Some of the treatment procedures are centuries old, while others are relatively new. Gemstones are treated differently to improve their appearance. Some of these procedures are centuries old, while others are relatively new. Moreover, by cutting or polishing gemstone could be fabulous nice colors and brightness. Treatment or enhancement of gemstones, any process to do better gem jewelry natural color, clarity before cutting and polishing. Please understand treatment and enhancement that has nothing to do with man created gems or synthetic gemstones. The treatment and improvement of the gemstone is very common way to improve the appearance of precious stones. Some improvements in treatment and improvement of nature are permanent and can not be detected. The treatment and process improvement looks so to what happens in nature, can not always know if they have been treated after mining or earlier. Microscopic examination reveals at times, an inclusion that burst during the heat treatment, but there is no way of knowing exactly that the heat treatment was carried out before or after mining. There are many techniques treatment or enhanced gems (More information on knowledge http://www.facedgem.com/gemstone-knowledge/gemstone-treatment.htm). In brief explanations of the important techniques is the following.
Oiled treatment method has been used more so that hundreds of years, most Emerald sought its beautiful green color and clarity. Similarly, other colored stones such as alexandrite and rubies are treated in this way makes the inclusions less surface. So we can conclude that the oils are used in colored gemstones to improve appearance. This treatment reduces fractures and provide better clarity. Heat treatment is the most common and better known. This is so common with corundum, ruby and sapphire, it is recommended that jewelers report clients that are "probably heat treated. Heating may cause the color of the stone to darken, brighten, or even completely changed, and may also improve the clarity of the gems. Heating of most types of gemstones is a standard treatment procedure. Knowledge Heating passed through generations. Heating methods vary from simple burning at very low technical method of temperature regulation (more on the knowledge http://www.facedgem.com/gemstone-knowledge/gemstone-treatment.htm). Diffusion is a method of improvement, commonly used on corundum, fortified with iron and titanium in the heating of the gemstone, sometime called surface diffusion. Diffusion layer created by adding elements. This coating layer is described as color. Improvement of radiation or irradiation means beating the material with subatomic particles. In some cases, irradiation is followed by heating to produce a good or the new color of the gem – such as topaz. So today irradiation technique applied and has created many nuances that are not found in natural topaz. Just as tourmaline, irradiation may become dark pink stone red. Diamonds in the irradiation and heating can become brown, blue, yellow, pink and green.
