Core-drilled cylindrical quartz specimen showing crystalline growth at the exposed end. The sample has a natural rough surface, clear quartz formation, and a section of the original host matrix visible at the base. The item was identified as a boring sample of quartz crystals based on accompanying bag labeling.
The surfaces exhibit characteristic luster, and the core shape suggests it was extracted for geological or educational purposes. See photos for Measurements if taken. Overall condition appears intact, with minor inclusions in the matrix.
