Gemlogis® Belize Pro - Diamond & Moissanite Combination Tester

The Gemlogis® Belize Pro Diamond Tester is an advanced synthetic diamond segregator and diamond tester, designed for professional jewelers, gemologists, diamond dealers, and gold traders who require accurate diamond testing, moissanite detection, and gemstone verification.

Built with enhanced detection technology, the Belize Pro improves identification of natural diamonds, including rare stones that may be less responsive to UV and can be incorrectly identified as moissanite by standard diamond testers. This makes it an essential tool for high-value diamond testing, jewelry authentication, and professional gemstone analysis.

Advanced Diamond Testing Technology – Thermal & Optical Combined
The Belize Pro combines thermal conductivity testing and optical testing into one device, providing fast, reliable, and precise gemstone identification. This advanced system allows quick differentiation between:

• Natural earth-mined diamonds
• Lab-grown diamonds (HPHT & CVD diamonds)
• Type IIa diamonds
• Moissanite (including F1 moissanite)
• Diamond simulants

With two testing modes — Default Mode (Thermal + Optical) and Q-Mode (Optical Quick Test) — this professional diamond tester offers flexibility for diamond sorting, jewelry testing, and gemstone verification.

Professional Jewelry Testing – Loose & Mounted Stones
Designed for real-world use, the Belize Pro can test both loose diamonds and mounted stones, including rings, pendants, and earrings with open or closed back settings. This makes it ideal for:

• Jewelry stores and workshops
• Diamond trading offices
• Pawn shops and gold buyers
• Gemological laboratories

The UV light activates only when the probe touches the stone, reducing exposure and ensuring safe operation during continuous testing.

Compact, Portable & Easy to Use
This portable diamond tester is lightweight, compact, and ergonomically designed for both left- and right-handed users. The large OLED display provides clear readings, while optional sound indicators allow quick result interpretation.

With built-in power-saving mode and automatic shut-off, the Belize Pro is ideal for daily professional use, whether in-store or on the go.
