Now identifying the quality of turquoise has become a knowledge worth studying. In order to help everyone better distinguish between natural turquoise and the common sense of green pine that is optimized, let me list a few points to identify turquoise. Common sense. The highest quality of natural turquoise is blue without optimized treatment. It will have pictographs and patterns on the surface. Because of its unique colors, it is very popular. The price of high -quality "blue porcelain pine" is equivalent to gold internationally. The natural turquoise that has not been optimized will emit a porcelain -like luster, and the stone is hard. To identify whether the turquoise has been optimized, the following two methods need to be passed. Water testing method: Generally, the turquoise used for inlaid inlaid is polished on the front, and there is no polished on the opposite side. You can dip the turquoise in the water during testing. It is that the turquoise -soaked turquoise water absorption will be slower, and the glue will not absorb at all. Put the naturally unprepared turquoise into the water, and the color will deepen, and the treated turquoise will not change in the water. Visual inspection method: There are many patterns on the surface of natural turquoise without optimized treatment, so there will be unevenness, and the optimized turquoise surface is very smooth. Many people will deliberately choose the smooth surface when they buy turquoise. In fact, most of them are green pine that has been optimized.
Use organic dye or inorganic dye dyeing green pine finished products can be identified in these several aspects: . The color of the dyed turquoise finished color is not natural and too uniform. It, the color dyed green pine finished products are very light. It, wipe the dyed green pine products with cotton ball dipped in ammonia water, which will make it color. If injecting plastic or inorganic salt colloids into the green pine finished product can improve its stability. Through the following two aspects, you can identify the turquoise finished products: . First, the green pine finished product of the gum is less density and the hardness is lower. Is to contact the concave pits or cracks on the surface of the heating needle or crack, which will produce a pungent plastic melting odor.
The natural turquoise appraisal characteristics are as follows: 1. The luster of the turquoise is far less than the glass of the jadeite, so the most common turquoise is wax -like luster. 2. Green pine is opaque jade. All the turquoise gathers are not transparent, while the jadeite glass, ice species and glutinous seeds can be translucent. Essence 3. Identification of turquoise has a typical logo feature, which is the iron wire. On the surface, it is concave, wide and narrow, and winding and turning, while other jade crusts do not have this phenomenon. . The dense turquoise is often used as a emerald substitute. They are often used to inlaid into various jewelry. Due to the precious metals inlaid, the distinction characteristics of density, hardness, and iron wires will become It is not practical enough, and it is important to examine the differential characteristics of the details of jewelry, granularity and other details.
