Problems solved by technology

[0002] Jewelry is a precious jewelry material, and its appreciation is extremely important. There are many conditions for gem appreciation in jewelry, and the identification method is single. It can only detect certain characteristics of it, and it is impossible to accurately identify its authenticity. Satisfy the appreciation of ordinary people;
[0003] There are certain disadvantages in the existing jewelry appreciation methods. First of all, the existing jewelry appraisal methods are mostly used for authenticity appraisal at the time of purchase. The appraisal method is single, and gemstones cannot be systematically identified. , Secondly, the traditional method of diamond identification mostly uses the method of characterization to detect the hardness, which is easy to cause damage to the smoothness of the diamond. Therefore, we propose a jewelry appreciation method

Embodiment 1

[0031] When checking for sapphire or ruby:

[0032] (1) The identification of gemstone types, using a refractometer to measure the refractive index of gemstones, rarely have two kinds of gemstones with the same refractive index, so the type of gemstones is determined by the refractive index, and the refractive index of the jewelry to be identified is 1.77. Determined as sapphire or ruby;

[0033] (2) The identification of gemstones and artificial gemstones, identify the sapphire or ruby ​​in step (1), use the color filter to observe the color of the gemstone is very pure, it can be determined that it is not artificially dyed gemstones, the color filter consists of two pieces that only allow dark red and ruby Composed of color filters through which yellow-green light passes;

[0034] (3) Appraisal of the appearance, identify the true gemstones in step (2) for appearance appraisal, observe with gem magnifiers and gem microscopes, observe with gem magnifiers under reflected ligh...

Embodiment 2

[0038] When testing for diamonds:

[0039] (1) The identification of the type of gemstone. Use a refractometer to measure the refractive index of the gemstone. Few two gemstones have the same refractive index. Therefore, the type of gemstone is determined by the refractive index. The detected refractive index is 2.42, and it is determined to be a diamond. ;

[0040] (2) The identification of the authenticity of diamonds, the gemstones classified as diamonds in step (1) are identified, and the thermal conductivity meter is used to identify and obtain authenticity results. When the thermal conductivity meter is in use, first turn on the power supply of the thermal conductivity meter , heat the metal needle-shaped probe for 20 seconds, then touch the hot needle to the surface of the sample to be tested, and judge the diamond as real according to the signal of the thermal conductivity meter;

[0041] (3) Appraisal of appearance, identify the true gemstone in step (2) for appearan...

Embodiment 3

[0044] When checking for emeralds:

[0045] (1) The identification of the type of gemstone. Use a refractometer to measure the refractive index of the gemstone. Few two gemstones have the same refractive index. Therefore, the type of gemstone is determined by the refractive index. The detected refractive index is 1.58, and it is determined to be a grandmother. green;

[0046] (2) identification of gemstones and artificial gemstones, identify the emeralds in step (1), use the color filter to observe the color of the gemstones, the green emeralds are red under the color filter, it can be determined that they are not artificially dyed gemstones, and the color filter is made of Composed of two color filters that only pass through deep red and yellow-green light;

[0047] (3) Appraisal of appearance, identify the true gemstone in step (2) for appearance appraisal, utilize gem magnifying glass and gem microscope to observe, observe with gem magnifying glass under reflected light, g...

Abstract

The invention discloses a jewelry appreciation method, which includes the following specific steps: identifying the type of a jewelry, and measuring the refractive index of the jewelry by using a refractometer, wherein the refractive indexes of two jewelries are rarely the same, so the type of the jewelry is determined by the refractive index; performing authenticity identification of the jewelry,identifying the jewelry and an artificial jewelry, and identifying the jewelry, of which the type is determined in the above steps. According to the jewelry appreciation method, the whole jewelry appreciation method can systematically identify the jewelry, judge the authenticity of the jewelry from main characteristic conditions, avoid inaccurate identification caused by single identification method, use a thermal conductivity meter to identify the authenticity of a diamond, is simple in operation, and does not damage the smoothness of the diamond, can maintain the original characteristics ofthe diamond, can accurately determine the authenticity of the diamond at the same time, and then cooperates with subsequent surface identification to complete quality detection of the diamond, thus bringing a better use prospect.
