Application of LA-ICP-MS in gemological field;Identification of natural and synthetic ruby

Abstract

We studied a way of separating natural and synthetic rubies on the basis of trace element chemistry. In this presentation, LA-ICP-MS analyzes a synthetic ruby produced by verneuil, czochralski, floating-zone, flux and hydrothermal method and it introduces the summary of the difference of a transition element(Ti, V, Cr, Mn, Fe, Ga etc) or a rare earth element.
