Most gemologists who have examined even a small number of opals from México with a microscope are familiar with at least two or three inclusions in this material, very few inclusions have as yet been conclusively identified.

After carefully studying several Mexican opals with included acicular crystals, the authors noted that in almost all cases there seemed to be a shell of whitish to pale yellow material surrounding the needle-like crystals.

The crystal shown is typical of the black, needle-like crystals found in Mexican opals. It is also opaque and is of slightly distorted hexagonal cross section. Crystals of similar appearance that did not reach the surface of the opal host had rhombohedron-like.
