Gemlogis® Belize Pro - Diamond & Moissanite Combination Tester

The Gemlogis® Belize Pro is an advanced diamond and moissanite combination tester, developed for professional jewelers, gemologists, and diamond traders who require maximum accuracy, especially when testing rare natural diamonds and small stones.

Built on upgraded technology, the Belize Pro offers a significant improvement over standard testers such as Belize, SmartPro, and Presidium, delivering reliable results where other devices may produce false readings.

Advanced Identification of Rare Natural Diamonds
The Belize Pro features enhanced detection technology capable of correctly identifying rare natural diamonds that may test as “moissanite” on conventional testers. These exceptional stones—most commonly encountered by U.S. clients—are not widespread but require advanced testing capabilities to ensure absolute confidence.

By addressing this limitation, the Belize Pro provides jewelers with greater assurance when verifying high-value stones, even those that are less responsive to UV-based testing methods.

Patented Twin-Probe Technology for Higher Accuracy
Equipped with patented twin probe tip technology, the Belize Pro delivers twice the accuracy compared to single-probe testers. This enables fast and precise differentiation between:

• Earth-mined natural diamonds
• Type IIa / HPHT / CVD diamonds
• Moissanite (including F1 moissanite)
• Common diamond simulants

The device is ASSURE tested and certified, ensuring professional-grade reliability.

New Melee Mode for Small Stone Testing
The newly introduced Melee Mode allows accurate testing of stones below 0.04 ct, making the Belize Pro especially effective for melee diamonds and pavé settings.

With the original Belize tester, testing small stones required high user experience, as metal interference from the setting could cause repeated beeping and incorrect detection. The Belize Pro minimizes metal detection during small stone testing, resulting in:

• Fewer false alerts
• Faster testing
• More consistent results, even for less experienced users

Battery-Operated for Easy Logistics & Air Freight
The Belize Pro is battery operated, making it easier to ship, store, and transport—especially for international logistics and air freight. This feature is particularly valuable for distributors, retailers, and traveling professionals who require a portable, logistics-friendly testing solution.

Compact, Ergonomic & Professionally Designed
Highly compact and lightweight, the Belize Pro is ergonomically designed to accommodate both left- and right-handed users. It supports testing of both loose and mounted stones, including open and closed back settings, adding versatility for real-world jewelry applications.

The device also connects wirelessly with Gemlogis Reference Meters (sold separately), enabling expanded testing capabilities for advanced users.
