STONEGO thermal conductor diamond hardness tester authenticity check

STONEGO thermal conductor diamond test for authentication is an innovative portable tool for determining the true properties of gemstones. This device uses thermal conductivity technology that in seconds identifies whether the stones are genuine diamonds or their substitutes. The Diamond Test for Authentication is ideal for both professional jewelers and collectors who want to see the value of their treasures. The device has LED indicators and an audible signal to obtain accurate readings.

Diamond Test for Authentication - main features

• Easy to use - Even beginners can immediately start using this device. Intuitive control and clear sound signals provide accurate results without technical preparation or special knowledge.
• Sound signals for accurate reading - The device emits characteristic sounds that clearly indicate the type of stone. Straight look and sound confirmation help prevent errors.
• Light for real diamonds - The green light of the LED indicator unequivocally confirms that the tested stone is a real diamond. This visual confirmation immediately raises confidence in the results.
• Metal detection - When the sondes accidentally touch the metal, the device emits a continuous glow, preventing false measurements and wear.
• Size adjustment for diamonds - Determination of large and small connection allows testing diamonds from -8 to + 8 points, gradually adapting to different sizes and pounds.
• LCD display and LED indicator - Digital images and luminaires provide fast, reliable information. The results seen are clear and easily understandable even in weak light.
• Do not respond to substitutes - Artificial stones such as cubic circles (CZ) do not receive any signal. This selectivity guarantees that only real diamonds and natural precious stones are tested.

Buyer questions

Q: Does this test really recognize all the diamonds?
The STONEGO test machine checks thermal conductivity and therefore works best with natural diamonds and artificial versions. However, artificial diamonds (grown in the laboratory) may differ in thermal conductivity. It is therefore highly recommended that this test piece should distinguish between genuine natural diamonds and simple substitutes (CZ, glass).

Kl: How long can one 9V battery be running?
One 9V battery is designed for tens or hundreds of applications depending on test frequency. It is recommended to change the battery when the LED indicator starts to slip or the signals become weaker. Simple aluminium batteries should be sufficient for a few months of normal use.

Q: Can I test jewelry already installed?
Yes, you can. If the stone is already installed in a ring or carolar, it is not necessary to remove it. Just remove the sonde cap and gently bring the sonde to the top of the stone without trying to direct contact with the metal or box.

STONEGO Diamond Test for Authentication - an integral helper for anyone who appreciates gemstones and wants to protect their investments. Reliable, portable and very efficient.
