Problems solved by technology

[0004] The second is to use the DiamondSure diamond confirmation instrument to identify. This instrument mainly detects the absorption line of the identified diamond at 415nm. This instrument can quickly and accurately detect most natural diamonds, but about 10% of natural diamonds do not have 415nm The absorption line at the place, this part will be misjudged as a non-natural diamond, and the misjudgm

Abstract

The invention discloses an identification device for distinguishing natural diamonds, synthetic diamonds and moissanite based on a transmission method. Herein, an accommodating cavity is enclosed by a base and a bottom plate, a battery, a main control board and a circuit board are arranged in the accommodating cavity, and an ultraviolet receiver is arranged on the circuit board; an accommodating through hole for placing a to-be-identified diamond is formed in the base and is opposite to the ultraviolet receiver; a light shield is hinged to the base, an ultraviolet light source connected with the circuit board is arranged in the light shield and comprises a first light source and a second light source, the wavelength of the first light source ranges from 250 nm to 280 nm, and the wavelength of the second light source ranges from 350 nm to 390 nm. The device has the beneficial effects that the device can quickly and accurately distinguish natural diamonds, synthetic diamonds and moissanite, the distinguishing accuracy can reach 99% or above, and the speed is high to identify one diamond per second. Moreover, the identification device is simple to operate, low in manufacturing cost and suitable for diamond manufacturers, jewelry manufacturers, detection stations and the like with large use amounts.

Description

technical field [0001] The invention relates to the technical field of diamond identification, in particular to an identification device for distinguishing natural diamonds, synthetic diamonds and moissanite based on a transmission method. Background technique [0002] There are mainly the following types of diamond identification devices commonly used in the existing market: [0003] The first is to use a 10 to 20 times magnifying glass to directly observe the characteristics with the naked eye to identify. Using a magnifying glass to identify requires the observer to have corresponding professional ability to accurately identify natural diamonds. [0004] The second is to use the DiamondSure diamond confirmation instrument to identify. This instrument mainly detects the absorption line of the identified diamond at 415nm. This instrument can quickly and accurately detect most natural diamonds, but about 10% of natural diamonds do not have 415nm The absorption line at the p...
