Introduction:
The spectroscope has developed slowly in its importance in gem testing,
for there are few gem varieties that have diagnostic spectra. In recent years
it has been used more frequently, because new uses for which it is valuable
have been developed. Among the important gemstones ruby, red garnet, some
blue and yellow sapphires, jadeite, zircon, alexandrite and emerald have characteristic
spectra, but the spectra of synthetic ruby and emerald are indistinguishable from those
of their natural counterparts. Its limited application led to concentrate efforts on
the development of such tools as dark-field illumination combined with binocular
magnification, the polariscope, and the spot method for R.I. determinations.
