Presidium Synthetic Diamond Screener
Helps screen out Type IIa colorless diamond, which is
likely to be synthetic and created through chemical vapor deposition
(CVD) or high pressure high temperature (HPHT) syntheses, from the natural
Type Ia colorless diamond. Uses UV irradiation, making the
difference in the light absorption significant enough to aid in differentiating
between colorless Type Ia and Type IIa diamonds.
Works on both mounted (with open-back setting) and loose diamonds.
Test diamonds as small as 0.1-10 ct.
Includes AC adapter, or 2 AA batteries (not included).
Protective zippered pouch, hard plastic outer case included.
