Sentinel — Diamond detection
Sentinel is DRC’s retail-counter model. Manufacturing bulk volume or melee?
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.

AI Powered Diamond Detection
Accurate. Intelligent. Reliable.
Marking
These stones are detected as lab-grown diamonds, likely HPHT-grown with no natural diamond characteristics observed.
Marking
These stones are detected as lab-grown diamonds, likely CVD-grown. If UV fluorescence is present, then likely it’s natural.
Marking
Re-scan the stone separately and verify the result with manual interpretation to ensure accurate and reliable identification.
Screening CZ
Dark orange or greenish glow under Screen 5 indicates Cubic Zirconia with a high degree of confidence.
Whether you’re a retailer enhancing customer trust or a diamond manufacturer running QC checks, Sentinel fits right in:
It’s a fully automated process that replaces manual sorting and measurement. Accelerating production while maintaining superior consistency and reliability.
