Usage & Care Notes
Be sure to fully charge the unit before first use; a low battery may reduce accuracy.
Use only the supplied USB-C cable and a 5 V/0.5 A charger (does not support high-power “PD” fast-charging).
Allow gemstones to cool between successive tests and wait for prior result to clear before re-testing. Heat buildup may affect accuracy.
Clean the tester’s tip gently after periods of inactivity; remove dust/oil from stones with a dry tissue for accurate results.
Unexpected or ambiguous results should be referred to a qualified gemologist for confirmation.
