Skeletal Quartz, From Pakistan, 712g

Skeletal quartz crystals differ significantly from the crystals commonly perceived by the public. Their distinctive appearance resembles that of an extraterrestrial spaceship.
In skeletal quartz, the edges grew more quickly than the faces, causing the edges to stand out like the frames of a window. During the growth process, the crystal’s surface is covered by soil, and new crystals cover the soil surface again. This cycle repeats, ultimately resulting in the formation of a three-dimensional and unique layered structure.
