Specification Brand : JJENXYYDS BulletPoint1 : 【High Quality Materials】: The gem refractometer uses hard aluminum alloy to create a work surfaces, which is scratch-resistant and sturdy, providing stable support for precision testing. It is equipped with an ABS engineering plastic power switch and built-in triple insulation protection to effectively block the risk of leakage BulletPoint2 : 【Jewelry Tester Identification Tool】: It is the most important tool for gem identification, and can measure the refractive index value of gemstones non-destructively, quickly and accurately. Refractive index test range 1.300-3.000 BulletPoint3 : 【Test Method】No refractive oil is required, just bring the sample's measuring surfaces close to the measuring platform to measure. Based on this parameter, you can determine whether the gem is a uniaxial crystal or a biaxial crystal BulletPoint4 : 【Working Principle】: The working principle of the refractometer is based on total internal reflection. The refractive index is a very important optical parameter, and the characteristics of gemstones can be determined based on this parameter BulletPoint5 : 【Wide Range of Applications】: Quickly and accurately identify single and double gemstones, diamond colored gemstones, designed for measuring the refractive index of gemstones and solid materials ExternallyAssignedProductIdentifier : 6417893801272 ItemName : JJENXYYDS Professional Jewelry Tester Identification Tool,Gemstone Refractometer,Refractive Index 1.300-3.000, with LCD Screens,for Jewelry, Gold & Silver and Diamond ItemPackageDimensions_Height : 10 centimeters ItemPackageDimensions_Length : 10 centimeters ItemPackageDimensions_Width : 10 centimeters ItemTypeKeyword : jewelry-diamond-testers Manufacturer : JJENXYYDS PartNumber : 79478473 ProductDescription : Gemstone Refractometer, Jewelry Tester Identification Tools with Large Lcd Backlight, Error: + -0.005/accuracy: 0.001/Refractive Index 1.300-3.000, for Test Jewelry
Jade Gem refractometer is suitable for identifying polished finished products. Jade jade can be tested to determine whether the refractive index of jade is It is in line with its numerical test of 1.66, and it is necessary to protect the jadeite There is a flat rough stone of at least 3mm
Hetian jade Gem refractometer is suitable for identifying polished finished products Hetian Jade can test whether the refractive index of Hetian Jade is It is a rough stone that meets its numerical value of 1.61
Jewelry Gem refractometer is suitable for identifying various types of gems stone, the number of refractions fixed by its various varieties of gemstones The value is used to determine whether the rough stone matches the characteristics of the gemstone.
Diamond Digital gem refractometer for identification of natural diamonds And artificial diamonds, the refractive index reaches 2.417 However, diamonds with refractive index between 1.98-2.2 are all artificial. Diamond, also known as zircon
