摘要：

The Fourier transform Raman (FT-Raman) spectra of a series of opals are presented. The opals characterised derive from a variety of origins in Australia and they are compared to opals originating from North America. The opals are distinguished by their crystalline morphology which is evident in the Raman spectra. As opals are based on the chemistry of silica, the vibrational spectra of a variety of polymorphs of silica are used to assign the spectra and identify the morphology of the opals.
