Abstract

Most artisans visually characterize Chiapas amber, mainly in appreciating the blue-green color emitted by fluorescence when incident ultraviolet light illuminates it. However, false amber pieces generate this coloration, misleading local and international buyers. Thus, we propose an optomechatronic device (OD) to determine whether amber from Chiapas is authentic. This device measures the fluorescence intensity and, through a database, determines whether amber is authentic. The infrared and ultraviolet spectroscopy techniques validated the results obtained with the OD.
