Important Function Clarification

This tester is intended for preliminary gemstone screening only.

It is designed to provide separate Diamond and Moissanite indications, but test results may be affected by gemstone size, temperature, surface condition, probe contact and operating method.

This tester does not determine whether a diamond is natural or laboratory grown. It also does not determine diamond clarity, color, cut, carat grade or origin.

For professional identification, grading or certification, testing by a qualified gemological laboratory is recommended.
