Etymology
Due to the image presented by the members, many of the name submissions had meanings which emphasizes the members' very different, yet complementary, personalities, and their cute and pure image.

Quartz is a type of crystal, so the name QU4RTZ is meant to represent the glamour presented by the unit. The 4 comes from the number of members.

Also, the "Quart" in Quartz can also be seen as a play on the word quartet, since the group consists of 4 members which make music together.

Other highlighted submissions are "PomPon" and "Q-PIDZ."
