How to use BELIZE, interpret the results and when to send the stone for Gem Laboratory testing

• Press the power button on to turn on BELIZE 
• Press both finger on the metal plates
• Gently clean the oxidation on the probe tip
• Clean the surface of the gemstone 
• BELIZE is a two tests instrument
• Perform Test 1 (Probe tip should always be pressed perpendicular to the table of the faceted stone, loose of mounted) 
• Perform a test on mounted stone, hold the jewellery with one hand and the tester with the other hand.
• To test loose gemstones, place the gemstone on the metal stone rest and hold it with one hand while holding the tester with the other hand.
• For Simulant, it will indicate Simulant directly after the Test 1.( BELIZE may also work in conjunction with Gemlogis Bleu to identify the type of stimulants) 
• If the stone is a Moissanite or Diamond, it will display “Moissanite and Diamond” then prompt for the second test “Perform Test 2” 
• Moissanite – Moissanite is detected 
• Diamond –  (Earth-mined), or (Type IIa, HPHT, CVD) is detected

Important Notes:

Simulant – It depends on the thermal inertia of the color stones. For low thermal-conductive stimulants such as glass and cubic zirconia will indicate a lower level on the indicator bar. For the higher thermal-conductive than other stimulants such as corundum and topaz will indicates a higher level on indicator bar 

Earth-Mined – IaA, IaAB, Ib, the diamond has not been colored enhanced by HPHT treatment, can be considered as a Natural Diamond

Type IIa, HPHT / CVD – IaB, IIa, IIb, the diamond may be synthetic, or color enhanced by HPHT treatment. Recommend to send the stone to a gem laboratory for further examination 

The Gemlogis BELIZE does not specifically confirm whether a natural diamond has been  enhanced by HPHT treatment. The Gemlogis BELZIE works accurately with known colorless diamonds (Color:D to J). Clarity:VVS1-S12
