Can the Source Location of a Coloured Quartz Gemstone Be Determined from Non-Destructive Chemical Analysis?

Coloured varieties of quartz are extremely common and several are classed as semi-precious gemstones. For a long time varieties of quartz have been used to make jewellery, carvings and other household objects. With the advent of new non-destructive chemical analysis techniques is it possible to determine the growth location or source of a quartz gemstone? This project is interested in determining what trace element variations are shown within quartz gemstones of the same colour but from different source locations such as America verses Africa. Also, can the source region be narrowed down even more so that the same coloured quartz gemstones from one part of a country can be separated from ones which grew in another part of the country based on their respective trace element compositions?
