5 thoughts on “How to distinguish diamonds with the naked eye”

First, pay attention to the gloss and scattered gem The diamond should show a typical King Kong luster. According to the color scatteredness of the diamond (0.044), the grinding standard diamond finished product should show obvious "fire color", but common artificial imitation diamonds (such as cubic oxidation, titanic acid pupa, aluminum gryngum ...
1. Look at the gloss and dispersion of light The polished diamonds are more dazzling than rough. At the same time, the standardized diamonds can better express its unique light with a strong dispersion color, manifested as a "fire color" with five colors and beating. Compared with the unique imitation diamonds with high decentralized colors, the scattered color of the diamond is soft and soft, and the dispersed diamonds with color machines and dazzling. However, to accurately control the difference between the scattered colors of diamonds and imitation diamonds, a large number of inspection is needed.
2. Line diamond appraisal test because the cutting of the diamond is usually standardized, almost no light can pass through the process of the pavilion, so when the diamond sample table is placed on a piece of paper with black lines, There is no black line on the paper on it. The same phenomenon can occasionally appear on diamond imitation with high refractive indexes, such as artificially manufacturing titanate and synthetic golden stone, but it is not seen as needed; Say, you can see the curved black line.
3. Harbin Qi Diamond Appraisal Experiment The breath of the test sample. If the water vapor of the sample appearance is quickly dispersed and it feels fresh, it is declared that the sample is diamond; The sample of stating is the imitation of diamonds. This is because of the high thermal guidance of diamonds. This is also called "breathing experiment" or "fog experiment". When doing this experiment, if the sample is small, you need to apply a magnifying glass to hold it. In addition, because the evaporation rate of water vapor is greatly affected by room temperature, this method should not be adopted in summer.
4. Fighting Effect This is a diamond appraisal method that determines the relative refractive index (especially suitable for the refractive index with a refractive index of 1.80). The measurement method is to place the table or bottom of the sample on the table on the paper with the tip of the handwriting. The scale of the white word traces can be seen through the sample.
5. Shadow diamond diamond identification The shadow map method is a method used to distinguish the refractive index greater than 1.81, single refractive and cutting: [to standardize the diamond -like diamond sample. During the inspection, the jewelry table must be completely immersed in the jewelry table with a diaodium methane solution. Take the shot jewelry and look at the shadow graphics projected on the white violation scene. The comparison of the shadow graphics of different products through the process can distinguish diamonds and their imitation products. 6. The water support test This sample completely washed the sample to make it without oil. After that, the droplets on the sample on the sample. If the water droplets can keep the sample appearance, it is stated that the sample is diamond; Expressing it, the sample is that the sample is the imitation of the diamond.

Some diamonds come with a document that provides information about its origin, which is a way to identify where a diamond comes from. Such certificates can even show which mines from diamonds are the best choice to verify that diamonds are really diamonds. In order to ensure the authenticity of the diamond, it is recommended to buy it from a reliable producer, and they will provide a diamond certificate to prove that its source is credible. For example, Russia's largest diamond producer is AlROSA.
In daily identification, there are some simple and easy ways to identify diamond authenticity: 1>. Line test: to wipe the diamond and place it down on the table on one line of paper On the top, if the proportional diamonds, It can not see this line through the diamond, and the vast majority of imitation products allow enough light to pass, at least a part of the line. 2>. Liquid Drop test: The ink will leave a line when the diamond pen is scratched on the surface of the diamond. In addition, water drops can be used. On the surface clean diamonds, the water will keep the spherical shape for a long time, and the water on the imitation products will dispersing in a relatively short period of time. This methods can help consumers preliminarily judge the authenticity of the diamond, and detailed in detail, and detailed in detail The quality of the quality also requires professional laboratories for detection and grading. 4. The mineral name of the emerald of emerald emeralds is green pillar stone. Because the mineral contains trace chromium, it presents a crystal and beautiful green. Green column stones are often in the shape of hexagonal columns and crystal output. Hardness is 7.5 to 8, the proportion is 2.67 to 2.78, and the discount rate is 1.56 to 1.60, transparent and crispy. In nature, there are many types of green and transparent gems similar to emeralds, and more common ones are jade, tourmaline, fluorite, olives, garnet, and vermiculite. Essence Observed with the naked eye, green emeralds are generally translucent, often with fiber spots, while high -quality emerald transparent and crystal. The hardness of emeralds is 7.5-8, while the fluorite hardness is low, only 4. The proportion of emeralds is small, while fluorite, tourmaline, and jadeite are large. The vermiculite is strong and has obvious double shadows. In addition, there are artificial emeralds, green glass, etc. similar to natural emeralds, etc. The biggest difference between them is that most of the natural emeralds have flaws or bodies and can be seen. Of course, it is necessary to strictly and correctly distinguish it. The hardness of emeralds, the same as ruby, is around 8.5, second only to diamonds, or it can be used to draw other stones with high hardness such as emerald/jade. If it is a ruby, it must leave traces on the jadeite. Essence If there is an emerald pendant, you can try it on his back.
