Abstract: Background: Amber is a plant product. Amber is formed by fossilization of original tree resins. Resin is a complex substances produced by plants. Amber has a very rich history and has been used for different purposes. For thousands of years, amber is used as an ingredient in perfumes, as decorative artifacts, as a healing agent in folk medicine, and as jewelry. Due to the higheconomic value of amber, it is made especially easy to fake of the Baltic amber. In this study we have aimed to investigate the potential of Raman spectroscopy in order to distinguish between the natural and fake amber. Ten different samples known as amber were investigated and selected center at 1300 cm-1 of Raman spectrum. Raman spectrums of samples were drawn with Matlab. While seven samples spectra were similar, three samples of them were different. The most characteristic peaks in the Raman spectrum of three samples (numbers of sample are 3, 7, 10) are fingerprint regions and strong features at 1204, 1446 and 1650 cm-1, respectively. The most characteristic peaks in the Raman spectrum of seven samples (numbers of sample are 1, 2, 4, 5, 6, 8, 9) are fingerprint regions and strong features at 776, 846, 998, 1259, 1435 and 1608 cm-1, respectively. Aman spectroscopy provided so quick analysis; non-destructive confirmatory identification and fake amber can be easily distinguished from the real amber. It is important in terms of take precedence against counterfeiting.
