How to Use Your Diamond Tester: A Quick Guide

Make sure your shine checks out. Here's how to use your diamond tester to verify authenticity like a pro:

Step 1: Power Up

• Insert the battery
• Turn it on and let it warm up for a few seconds until the ready light is on.

Step 2: Set the Sensitivity

• Adjust the level based on the size of the stone (larger diamonds = lower sensitivity).
• Our tester have a guide — follow it based on carat size.
• Rule of thumb: set the level at 3-4 for 1ct diamond

Step 3: Clean the Stone

• Wipe the diamond gently with a cloth to remove oils or residue.
• A clean stone gives a more accurate reading.

Step 4: Hold Properly

• Hold the tester like a pen.
• Make sure your hand is touching the metal part (usually on the back or side) to ground the circuit.

Step 5: Test the Stone

• Gently place the tester tip perpendicular to the diamond's surface.
• Apply light pressure — don't jab it.

Bonus Tips:

• Always test one stone at a time.
• Don’t test mounted stones from the side — test from the top (table).
• Avoid metal settings — touching them may affect results.
