Look at this picture:
Maximizing the specimen a concavity is well recognizable (1).
Two sharp and regular bended edges (2), inside and outside the concavity, joining a flat surface (3) are distinguishable in the bottom part.
The flat surface seems to terminate at the beginning of a tapered part (4).
The reflectance is strongly nacreous, not glassylooking as if it’d be for a grain of quartz.
Three flakes mutually separated by compound fractures are recognizable on the upper part (5). It seems that flakes are held over the specimen through
an underlying matrix.
The appearance of the upper part of the specimen would seem to indicate a possible continuity between the part slightly emerging from the matrix and
the part well exposed so that an oval shape is conceivable (6).
The general appearance of the specimen is more similar to a shell than a grain of quartz or a grain of any known terrestrial mineral.
I'm not telling you what it is...I'm just asking you what do you think it may be...
Sorry for my poor english...it's not my native language...
