Frequently Asked Questions
Q: Can this diamond tester distinguish between real diamonds and cubic zirconia (CZ)?
A: Yes! The Gaqqee Diamond Tester uses thermal conductivity technology to accurately differentiate genuine diamonds from common simulants such as cubic zirconia (CZ). The LCD display and LED/audio indicators provide a clear real-or-fake result within seconds.
Q: Does the diamond tester work on set jewellery as well as loose stones?
A: Absolutely. The non-destructive probe tip can be applied to both loose gemstones and stones that are already set in rings, pendants, or other jewellery, as long as the stone's surface is clean, dry, and at room temperature.
Q: What battery does the tester require, and is it included?
A: The Gaqqee Diamond Tester is powered by a standard 9V DC battery (not included). You will need to supply one 9V battery before use. The device features a convenient low battery alarm to let you know when a replacement is needed.
Q: What environmental conditions are needed for accurate readings?
A: For best results, use the tester in an environment between 5°C and 35°C (41°F–95°F) with relative air humidity no greater than 80%. Stones must be clean, dry, and at room temperature prior to testing.
