The Gemlogis® Belize Pro Diamond Tester is an advanced professional diamond tester, synthetic diamond segregator, and moissanite detector, designed for jewellers, gemologists, diamond dealers, gold buyers, and jewellery professionals who demand accurate, reliable gemstone testing.

Featuring enhanced thermal conductivity and optical testing technology, the Belize Pro helps identify natural earth-mined diamonds, distinguish potential lab-grown diamonds, and detect moissanite and diamond simulants.

Its advanced detection system is particularly useful when testing rare natural diamonds that respond weakly to UV light and may be incorrectly classified as moissanite by conventional diamond testers.

Whether you're authenticating jewellery, checking diamonds before purchase, or sorting gemstones in a professional workshop, the Gemlogis Belize Pro offers fast, convenient, and dependable testing.

Advanced Diamond Testing – Thermal & Optical Technology
The Belize Pro combines thermal conductivity testing and optical detection in one compact device, helping jewellery professionals quickly differentiate between:

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

This combined testing technology improves diamond screening accuracy and reduces the risk of incorrect identification when compared with basic thermal-only diamond testers.

Two Professional Testing Modes:

• Default Mode (Thermal + Optical): Combines both testing methods for comprehensive diamond and gemstone screening.
  
• Q-Mode (Quick Optical Test): Provides fast optical testing for convenient diamond sorting and verification.
  

These dual testing modes make the Belize Pro an excellent choice for professional diamond screening, jewellery authentication, and everyday gemstone testing.

Test Loose Diamonds & Mounted Jewellery
Designed for practical use in the jewellery trade, the Gemlogis Belize Pro Diamond Tester can test both loose stones and diamonds mounted in finished jewellery.

Suitable for testing:

• Loose diamonds and gemstones
  
• Diamond rings and engagement rings
  
• Pendants and necklaces
  
• Earrings and other diamond-set jewellery
  
• Stones in open-back and closed-back settings
  

This versatility makes the Belize Pro a valuable testing instrument for jewellery shops, diamond traders, gold buyers, pawn shops, jewellery workshops, and gemological laboratories.

The integrated UV light activates only when the testing probe makes contact with the stone, helping minimise unnecessary UV exposure during repeated testing.

Compact, Portable & Easy to Operate
The Belize Pro is designed for everyday professional use, combining advanced diamond testing technology with a lightweight, ergonomic design.

Weighing just 105 g, this portable diamond tester is comfortable to handle and suitable for both left- and right-handed users.

The large OLED display provides clear, easy-to-read test results, while the optional audible indicator allows convenient testing in busy jewellery environments.

Additional features include:

• Compact and lightweight portable design
  
• Large OLED display for clear results
  
• Optional sound indicator with on/off control
  
• Ergonomic operation for left- and right-handed users
  
• UV activation only when the probe touches the stone
  
• Built-in power-saving mode
  
• Automatic shut-off function
  
• Operation using AAA batteries or USB power

The Gemlogis Belize Pro combines professional thermal and optical testing technology to provide a convenient solution for screening natural diamonds, lab-grown diamonds, moissanite, and diamond simulants.

Unlike basic diamond testers that rely primarily on thermal conductivity, the Belize Pro offers additional optical testing capabilities, making it particularly useful for modern jewellery businesses handling both natural and synthetic diamonds.

Equip your jewellery business with the Gemlogis Belize Pro Diamond Tester for faster, more confident gemstone screening and professional diamond verification.

Gemlogis Belize vs Belize Pro – What's the Difference?
The Gemlogis Belize Pro offers enhanced diamond detection technology compared to the standard Belize, combining thermal conductivity and optical testing with two selectable testing modes for greater flexibility.

Both models test natural diamonds, lab-grown diamonds (HPHT & CVD), moissanite, simulants, and individual melee diamonds from 0.02 ct.

The Belize Pro provides improved detection of rare natural diamonds with weak UV responses, helping prevent misidentification as moissanite. It also features a large OLED display, optional sound indicators, and wireless connectivity with Gemlogis Reference Meters.

For professionals seeking enhanced detection capabilities and greater testing flexibility, the Belize Pro is the more advanced choice.
