Today I would like to recommend a very practical diamond tester pen the DK7000 Multi II from  GemTrue

There are some reasons why I like him so much :

• Highly accurate diamond tester pen makes sure you never buy a fake stone again
• Check for diamonds, moissanite, as well as other stones and stimulants such as CZ
• 360-degree illuminated tip along with audio tunes provide you with easy and clear test results
• Comes with an extremely durable 0.6mm thermoelectric probe

Here is the video that can teach you how to operate it 👇👇👇
