Let's find out What is a diamond tester? Please refer to the following article.

What is a diamond tester?

Diamond test pen is a product with a small, pointed tip, compact design, easy to carry with you. This product is used to identify stone hardness, thermal conductivity, thermal conductivity, etc. to assist in distinguishing between diamonds and other stones. It's not always easy to tell whether the product you're buying is made from real or fake diamonds. Therefore, if you are not sure about the quality of the stone you want to buy or own, use a tester or go to any store to have the stone tested.

The pen will use rechargeable battery power for convenience in use. Includes a probe that makes contact with the product, a place to hold the product, a rechargeable battery, a light/result notification board, and a signal speaker.

The pen can test diamonds by properties: hardness, electrical conductivity or thermal conductivity... Depending on the pen type, it will test one of the above properties.

What is a diamond tester used for?

If you want to sell or trade your diamond, a diamond will usually be tested with a diamond tester, as they are not always easily identifiable.

Before repairing a piece of jewelry, jewelers need to check the structure of the stone because they have different resistance to heat, pressure and stress.

However, you should be aware that pens that rely on thermal conductivity may mistake a moissanite for a diamond because they have similar thermal conductivity. This problem can be solved by using a device to test the conductivity of two stones, because they have different electrical conductivities.
