International diamond technology company Yehuda has announced an update to its AI-powered laboratory-grown diamond detection system, introducing enhanced capabilities to identify newer “stealth” chemical vapour deposition (CVD) diamonds that may be difficult for older screening devices to detect.

According to the company, the upgraded AI model has been trained using extensive testing data and is designed to improve the identification of increasingly sophisticated laboratory-grown diamonds entering the market. Yehuda stated that the system has been evaluated on hundreds of thousands of stones and is intended to support more reliable detection across both loose and mounted diamonds.

The company said the update reflects the rapid evolution of CVD production techniques, which have created challenges for legacy detection equipment. It added that continuous AI training and expanded datasets are being used to refine the detector’s performance and reduce false positives while maintaining high detection accuracy.

Yehuda also noted that it plans to further expand testing across large volumes of diamonds to strengthen the model’s capabilities as manufacturing methods continue to evolve.

The announcement highlights the growing importance of advanced screening technologies for the diamond trade as synthetic diamond production becomes more sophisticated. Detection systems are increasingly being adopted by manufacturers, laboratories, wholesalers and retailers to support product verification and maintain confidence in natural diamond supply chains.

The latest update underscores the ongoing technological race between laboratory-grown diamond production and detection, with equipment providers continuing to enhance their systems in response to changes in synthetic diamond manufacturing techniques.
