The Screen-I is a portable diamond verification instrument designed to intelligently separate natural diamonds (Type Ia) from HPHT/CVD synthetic diamonds (Type IIa) in the colorless to near-colorless range (D to J).
It can also test mounted stones (only on jewelry with an open back).
The Screen-I operates manually but provides an automatic test result.
Additionally, its battery life lasts up to 150 hours of intensive use, offering convenience and ease during the testing process.
