Lab Grown Diamond Tester

Simulate UV fluorescence tests for CVD and HPHT synthetic diamonds.

LAB GROWN TESTER

Simulate advanced UV light and phosphorescence testing used to identify Chemical Vapor Deposition (CVD) and High-Pressure High-Temperature (HPHT) synthetic diamonds.

UV Fluorescence Scan

Standard pen testers cannot separate natural diamonds from lab-grown because they share the same physical, chemical, and optical properties. Advanced machines use short-wave UV light to detect specific phosphorescence (glow in the dark) patterns unique to synthetic growth methods.

Lab Grown Basics

CVD (Chemical Vapor Deposition) creates diamonds from a hydrocarbon gas mixture, layer by layer, in a vacuum chamber.

HPHT (High Pressure High Temperature) simulates the extreme natural conditions of the Earth's mantle using massive mechanical presses.

Important: A standard handheld $20 diamond tester will always beep "Diamond" for a lab-grown diamond, because structurally, they are real diamonds. Distinguishing them requires specialized UV and spectroscopic equipment costing thousands of dollars (like the simulator above) or review by a GIA gemologist.

About Lab Grown Diamond Tester

Because lab-grown diamonds (CVD and HPHT) are physically, chemically, and optically identical to natural diamonds, standard thermal testers cannot tell them apart. Specialized equipment measuring UV phosphorescence is required. This simulator demonstrates how machines excite the stones with short-wave UV light, revealing the distinct phosphorescent glow and silicon-vacancy (SiV) defect signatures unique to synthetic growth methods.
