Abstract
Section titled āAbstractāAbstract The advancements in Science and Technology introduced Lab grown diamonds (LGDs) that meet with diverse applications. The LGDās possess similar electrical, optical and mechanical characteristics compared to natural diamonds mined from earth. There is a possibility of LGDs infiltration in the Natural diamond pipeline in the jewellery industry. Hence, it becomes crucial to detect LGDs. The present article illustrates the importance of Raman Photoluminescence over absorption spectroscopy and Fluorescence/Phosphorescence imaging for identification of diamond nature. In the current work, a single Laser source of 532 nm was used to obtain the distinct molecular information of Natural diamonds and Lab Grown diamonds.
