Key Factors of ASSURE Test (previous model working on the same principle):
-
Accuracy of natural diamond recognition (Diamond Accuracy): The device achieved accuracy of 97.5% when identifying natural diamonds. This means that most natural diamonds were correctly recognized as natural. Using the subsequent analysis of diamonds marked by the device as synthetic under UV light, this metric can be significantly improved.

-
Synthetic diamond recognition accuracy (Synthetic Diamond Accuracy): The device achieved 100% success rate when recognizing laboratory-grown (synthetic) diamonds. This means that all tested laboratory-grown diamonds were properly identified.
-
The rate of synthetic diamonds marked as natural (Diamond False Positive Rate): The device had a 0% false positive rate, which means that no synthetic diamond was erroneously labeled as laboratory-grown.
Other observations:
-
Accuracy and reliability: The device is very reliable in distinguishing between laboratory-grown and natural diamonds. It can confidently recognize 100% of laboratory-grown diamonds.
-
Possibility of error with natural diamonds: There is a small probability (approximately 2.5%) that the device will flag a natural diamond as laboratory-grown. This phenomenon is known as a "false positive".
-
Additional check under long-wave UV light (Long Wave UV Light): If the device marks the diamond as laboratory-grown, further inspection can be performed under long-wave UV light. If the diamond under this light shows blue fluorescence, it is a confirmation that it is a 100% natural diamond. This method can further help reduce the percentage of false positive results.
