Safeguard your diamond pipeline with the Presidium Synthetic Diamond Screener II (SDS II). This advanced desktop instrument utilizes UV light transmittance technology to instantly separate natural colorless diamonds from potentially synthetic Type IIa stones (CVD/HPHT). Designed for rapid, high-volume testing, it delivers definitive results in just 2 seconds, making it an indispensable asset for busy jewelry retailers, gemological labs, and diamond wholesalers.

Key Features & Benefits

  • Advanced UV Transmittance Technology: Accurately measures a diamond's UV light absorption. It uses intuitive color-coded LED indicator light bars—Blue for Natural Diamond and Red for Type IIa Diamond—giving you instant, foolproof visual confirmation.

  • Rapid High-Volume Testing: Delivers clear results within 2 seconds. The unit features a convenient 5mm metal bar to raise the test probe, allowing for seamless, rapid successive testing on loose stones.

  • Versatile Testing Parameters: Engineered to test colorless diamonds (D to J color) ranging from tiny 0.02-carat melees up to massive stones over 10 carats.

  • Loose & Mounted Compatibility: Accurately tests all diamond cuts as long as the gemstone has a flat surface. It is also fully compatible with mounted jewelry featuring an "open-back" setting.

  • Smart Safety & Ergonomics: Protects the user with an automatic interior LED shutdown when the lid is open. It also features a blinking red alert if no stone is detected on the photo-detector, an energy-saving 10-minute auto power-off, and an exterior foam base for non-slip workbench stability.

High-Volume Diamond Buyers & Wholesalers: Perfect for rapidly screening large parcels of loose diamonds (from tiny 0.02ct melees up to 10+ carats) with definitive results in just 2 seconds per stone.

Jewelry Retailers & Pawn Shops: An essential frontline defense for verifying the authenticity of colorless diamonds (D-J color) before purchasing, trading, or appraising, preventing costly intake mistakes with lab-grown CVD/HPHT diamonds.

Gemological Laboratories: A reliable, desktop-grade initial screening tool that uses advanced UV light transmittance to instantly separate natural diamonds from potentially synthetic Type IIa stones.

Testing Mounted Jewelry: Great for quick authentication without unsetting the stone. It accurately tests diamonds already set in rings, earrings, or pendants, provided the piece has an "open-back" setting.

Professional Bench Jewelers & Custom Studios: Ideal for strictly securing your gemstone supply chain and building unwavering customer trust by ensuring every stone used in a custom build is a natural diamond.
