Your Trusted Eye for Diamond Authenticity
Meet Sentinel™ – The intelligent lab-grown diamond detection system
that identifies CVD, HPHT, and CZ instantly.
Now AI-powered, zero-interpretation, and designed for effortless screening.
THE PRODUCT
Sentinel by DRC is a compact, AI-driven diamond detection
system designed to identify CVD, HPHT, and CZ with precision and speed.
Built for jewellers, graders, and manufacturers, it simplifies detection with dedicated output screens—no colour checking or guesswork needed. It’s also the first in its class to offer identification of Cubic Zirconia (CZ) – minimising the confusion of ‘unknown’ results. While CZ detection may not always match the precision of lab-grown identification, it delivers clarity in most real-world scenarios.
Manual Detection Was Never the Future. Sentinel Is.
CVD, HPHT, and even CZ (Cubic Zirconia) using advanced fluorescence mapping and AI bifurcation. Equipped with a detachable
display, it fits perfectly in both retail and back-office environments — whether you’re showing results to a customer or sorting in production.
🔹Confused by color shades or result markings?
Sentinel eliminates interpretation — AI gives you dedicated result screens.
🔹 Tired of mixing up synthetics and non-diamonds?
Sentinel separates HPHT, CVD, and CZ instantly.
🔹 Want to show results live to your customer?
Use the rotatable screen for a clean, transparent experience.
🔹 Need a compact system that just works?
Plug it in—press Start. See clear, confident results in under 1 minute.
Smart Features That Work Where You Do
It’s a fully automated process that replaces manual sorting and measurement.
Accelerating production while maintaining superior consistency and reliability.
CVD / HPHT / CZ Identification
Detects lab-grown CVD & HPHT diamonds and positively identifies Cubic Zirconia — including mounted stones, rough, and polished formats.
Fast, Fully Automated Scanning
No input or manual interpretation required. Detection completes in 45–60 seconds per stone.
AI Result Bifurcation
Three dedicated result screens (CVD / HPHT / CZ) generated by a proprietary AI algorithm built over 12 years of R&D.
Detachable & Tiltable Display
User-friendly screen to share results directly with customers or operate in side-by-side layout.
Smart Interface with Touch Control
Effortless operation through touchscreen interface — ideal for retail counters and sorting rooms.
