Presidium Ari Tester

*ARI is developed as a handheld PRESIDIUM DIAMOND VERIFICATION INSTRUMENT™ to help

identify colourless diamond against CVD/HPHT lab grown colourless diamond and all types of moissanite.

*It is suitable for testing on both loose and mounted stones, including jewelry pieces with a closed back setting.

*Through advanced proprietary technology, ARI measures the UV light absorbance ability of diamond and moissanite.

*With its touch screen colour LCD display, ARI provides a clear and accurate result of “Diamond”,

“CVD/HPHT/Type IIa” and “Moissanite” within 3 seconds.

*Alert Buzzer for loss of contact between optical probe tip and diamond during testing

*A 6-Language selection in the Graphic User Interface (GUI)

*Tests on colourless diamonds and moissanites from D to J colour

*Tests on polished diamonds and moissanites of all proportional cuts as small as 0.02ct



SYNTHETIC DIAMOND

Synthetic diamonds are types produced in a laboratory environment by applying 

artificial process. They are divided into two as CVD and HPHT.It is quite difficult to distinguish it from

real diamonds, and it is distinguished by gemology laboratories using special devices. With

PRESIDIUM ARI which Presidium has just released, it can be tested whether the diamonds are

produced in real, mossanite or laboratory environment (CVD, HPHT). 



MOISSANITE

Moissanite stone is naturally formed in the world known as silicon carbide

is a mineral. It is brighter than all known gemstones. From 1893, the French scientist Dr. It was

discovered by Henri Moissan and named moissanite in memory of him. It is the hardest stone after

diamond (9.25). PRESIDIUM ARI is used to distinguish moissanite from diamond and laboratory stones "
