The collecting of antiquities has been popular since Roman times. In recent years, however, this practice has become more and more disheartening for archaeologists as they try to piece together history. Private collections donated to museums often lack the provenience of the artifacts and include many fakes. Such is the case with the collection of greenstone artifacts privately donated to BYU's Museum of Peoples and Cultures starting in the 1970s. An analysis of this collection strove to develop a methodology of identifying the fake from the authentic artifacts through non-destructive methods. Initially, visual examination of the artifacts was completed including microwear analysis and recording the color and density of the stones. Further authenticating methods included microscopy, X-ray florescence, and SEM (scanning electron microscope). Through a thorough examination of the density and color of the stone as well as the elements present as shown by the PXRF scan, an endeavor was made to identify what stone the artifact was made of and its source. Using the resulting data, a detailed catalog was created of the artifacts. Employing these same analyses, museums everywhere can check the authenticity of donated collections and possibly source the artifacts.
