GEMORO® TESTEROSSA DIAMOND, MOISSANITE & WHITE SAPPHIRE TESTER

Stop Guessing. Start Knowing. Whether you’re buying a pre-owned engagement ring, inherited an heirloom, or want to verify your latest online purchase, the GemOro® Testerossa gives you professional-grade certainty in seconds. Made in the USA, this is the most advanced handheld tester available, specifically designed to catch even the trickiest "Super Moissanites" (like Forever One™) that fool cheaper devices.

Why You’ll Love It:

• It Talks to You: No need to memorize complicated charts. The Testerossa can announce results in 9 languages (including English and Mandarin). It literally tells you if your stone is a "Diamond," "Moissanite," or "Sapphire."

• Foolproof Color Coding: The entire tip glows to give you an instant visual answer. Green means Diamond, Blue means Moissanite, and Pink means Simulant.

• Safe for Your Jewelry: The "Red Metal Alert" sounds an alarm if you accidentally touch the metal setting instead of the stone, preventing false readings and protecting your ring.

• Extreme Durability: This is a lifetime investment. It features an industry-leading 10-year probe tip warranty—it’s built to last as long as your jewelry collection.

• Bonus Watch Tester: Ever wonder if your luxury watch has a real Sapphire crystal? The Testerossa identifies genuine sapphire glass on watches too!
