Luminescence is an optical characteristic of materials under optical illumination. We have studied the luminescence of gemstone samples of nephrite which are common in Aceh. The samples were illuminated using two laser beam, green laser at 543 nm and red laser at 633nm.The transmitted and scattered light from samples were then resolved using a prism and characterized using spectrometer. The analysis shows a various luminescence and optical absorption across samples, which is due to some minutes of impurity in Aceh's natural nephrite. © Published under licence by IOP Publishing Ltd.
