Under short-wave UV light, CVD diamonds typically display a blue-green fluorescence, which is caused by trace amounts of boron or nitrogen impurities in the diamond crystal lattice. This occurs when the impurities absorb energy from the UV light and re-emit it as visible light in the blue-green portion of the spectrum.It's important to note that not all CVD diamonds will exhibit fluorescence under short-wave UV light, and the intensity and color of the fluorescence can vary depending on the diamond's composition and other factors. It's important to remember that fluorescence alone does not necessarily indicate the quality or value of a diamond, and other factors such as size, color, clarity, and cut quality are also crucial in determining a diamond's value.
