Description

Technical Field

[0001] The invention relates to the technical field of spherical jewelry identification, in particular to a handheld pearl identification auxiliary device and a pearl identification method thereof. Background Art

[0002] Jewelry can be divided into broad and narrow senses. In the narrow sense, jewelry refers only to jade products. In the broad sense, jewelry should include jewelry, crafts or other collections made of gold, silver and natural materials (minerals, rocks, organisms, etc.). Jewelry with certain value is collectively called jewelry. Therefore, in ancient times, there was a saying of "gold, silver and jewelry" to distinguish gold, silver and jewelry. With the development of society and economy, in addition to natural gemstones and artificial gemstones, the concept of jewelry should be expanded to include gold, silver, jewelry, etc. The industry that operates these items is collectively called "jewelry industry". The scope of "jewelry" is much larger than the broad concept of "gemstone". In the broad sense, gemstone refers to those raw materials that are suitable for grinding or carving into jewelry or crafts.

[0003] As jewelry circulates in social life, due to the extremely high value of jewelry itself, its investment prospects and its non-renewable mineral resource attributes, more and more consumers and investors have begun to pay attention to the jewelry market. However, most consumers lack the knowledge and tools to distinguish between true and false. Criminals often pass off inferior goods as good ones to grab high profits, and buyers are prone to suffer serious economic losses. A large number of fakes increase the risk of purchase and disrupt the market order. When identifying spherical jewelry and quasi-spherical jewelry, appraisers often use the method of holding the jewelry in their hands under the light for human eye recognition. When the fingers hold the jewelry, certain fingerprints or lines on the identification gloves will be left on the surface of the jewelry, which will affect the appraiser's identification of the jewelry lines. In addition, due to the influence of light during identification, the light needs to be kept stable.

[0004] In the prior art, manual or electric tools such as pliers are usually used to clamp jewelry, but the existing tools have the risk of over-clamping and causing damage to the jewelry. The main reason is that the detection of the clamping degree is still based on the operator's feeling or relying on sensors and other equipment; however, there are many uncontrollable factors in the above detection methods. Once the clamping degree detection fails, it often causes over-clamping, which has a great risk of causing damage to the jewelry.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Summary of the invention
