SYNTHETIC DIAMOND TESTER - PRESIDUM SDS II

PRESIDIUM SYNTHETIC DIAMOND SCREENER 

Identifies synthetic loose and mounted diamonds through 
its low UV absorption 

The Synthetic Diamond Screener is developed to help screen 
out synthetic Type lla colorless diamonds, which are likely to 
be synthetic and created through chemical vapor deposition 
(CVD) or high pressure high temperature (HPHT) syntheses, 
from natural type Ia colorless diamonds. 

When subjected to this deep UV irradiation, type Ia and 
type IIa diamonds each absorb different amount of UV light. 
Type IIa diamonds allow deeper UV light to pass through 
and thus its UV light absorption ability is low. This different 
in the light absorption is significant enough to aid in 
differentiating between colorless Type Ia and Type IIa diamonds. 


Features: 
- Advanced technology that measures a diamond`s UV light 
transmittance ability 
- 2 color coded (blue/red) indicator light bars to give a low 
or high reading of UV light absorption with blue light indicating 
natural diamond and red light indicating a type IIa diamond 
- Instantaneous clear results within just a few seconds 
- Low battery indicator 
- Energy-saving auto power-off of device after 10 minutes 
without operation 
- Energy-saving auto power-off of interior LED light source 
when lid of device is open or when Start Test button 
is not activated
