GemOro UltraTester 3+ Diamond, Moissanite & White Sapphire Tester

Add a multi-material screening tool to a jewelry inspection routine when a basic thermal diamond test leaves unanswered questions.

Features and specifications

• UltraTester 3+ model.
• Designed to screen diamond, moissanite, and white sapphire.
• Handheld electronic tester.

Who it suits

Relevant to experienced users comparing common colorless gemstones. Follow the model’s setup and probe-contact instructions rather than applying the routine from a different tester.

Before you choose

Material screening is not a determination of natural origin, treatment, clarity grade, or value. Mounted stones and poor contact can complicate testing. Ask a qualified gemologist to resolve conflicting results.
