The BIG Sherlock – CVD & HPHT Lab-Grown Diamond Detector by Yehuda

The BIG Sherlock by Yehuda is a powerful, next-generation CVD and HPHT lab-grown diamond detector built for jewelers, laboratories, and diamond professionals who need maximum accuracy at high volume. Using the same 100% detection-rate technology trusted in the Sherlock Holmes 2.0, this advanced device delivers reliable results for both loose stones and mounted jewelry.

Designed for efficiency, the BIG Sherlock can check up to 108 rings at a time on five rotating ring holders or approximately 1,000 carats of loose diamonds in a single session. Its large 8" × 11" (20 × 30 cm) scanning area and 4" (10 cm) height capacity make it ideal for rapid, high-capacity testing.

With secure cloud integration, you can save, manage, and compare test results with ease. Add or remove users, upload photos, certificates, names, and SKUs, and organize your data directly from a clean and intuitive back-office dashboard. Storage is included for approximately 1,000 test results, with optional upgrades available. Each user subscription is only $10/month.

Built for professionals who demand accuracy, speed, and clarity, the BIG Sherlock comes with a full one-year warranty and Yehuda's proven reliability.
