Presidium SDS II Synthetic Diamond Detector, Identifies CVD & HPHT Lab-Grown Diamonds

Portable device for instant (2-sec) screening of colorless diamonds. Clearly identifies Type IIa (CVD/HPHT) lab-grown diamonds and distinguishes them from natural Type Ia diamonds using UV light analysis. Tests loose and mounted stones (0.02-10 ct) with simple blue/red LED results. Essential for jewelers.

• Instant Screening for Type IIa Diamonds: Specifically designed to quickly identify colorless Type IIa (CVD/HPHT) lab-grown diamonds and distinguish them from natural Type Ia diamonds in just 2 seconds.
• Dual LED Visual Indicators: Features clear blue and red LED lights for immediate, unambiguous results—blue for natural Type Ia diamonds and red for potentially synthetic Type IIa diamonds.
• Wide Versatility for Loose & Mounted Stones: Accurately tests a wide range of stones from 0.02 to 10 carats, including popular cuts, and works on both loose stones and those in open-back settings.
• Professional UV Light Analysis Technology: Utilizes advanced UV light absorption analysis to ensure reliable and non-destructive screening of diamonds in the D-J color range.
• Precision-Engineered for Accuracy: Equipped with a blue platform light and a metal stopper to ensure correct stone placement and consistent, precise testing every time.
