Triplet 10X Hexagonal 20.5mm Illuminated UV & LED emission with toggle switch to check for flourescence in diamonds.
Be aware that while the majority of diamonds on the market will have a blue glow under UV light, high quality diamonds will not. The UV light method should be performed along with other tests to detect a fake diamond.
Cubic zirconia may glow mustard yellow under a UV light. Glass will have no glow at all.
Familiarize yourself with the other methods of detecting fake diamonds, such as the reflection colors within the stone, the weight, the quality of the setting and the wear and tear on the stone itself.
Use our PRestige II Reference D0089 or D0110.
Know that the final word on detecting a fake diamond is a professional appraisal. A certified and experienced gemologist will have the knowledge and skills needed to determine without a doubt that the diamond in question is authentic or a fake.
