How To Ensure Your
Tester’s Accuracy
To ensure that your gemstone tester is providing correct readings,
follow these simple steps every time you use your tester:
1.
Make sure that the gemstone you’re testing is clean, dry
and at room temperature.
2.
Clean the tester probe (tip) after every test by scratching it
vigorously against a piece of paper.
Please Note:
Do not scratch
the tip against paper that is coated or waxed. Make sure the tip
is securely seated.
3.
Do not performmultiple tests on the same stone in rapid
succession, as this will heat the stone and may cause inaccurate
readings. Wait 3–5 seconds between each stone test.
