Neptunite ネプチュナイト

A reserved, quiet gem who mainly does patrol duty. They're partners with Benitoite.

Neptunite has a sharp tongue and believes that people should face the truth head-on, regardless of how it makes them feel. Other gems comment that Nepti is very difficult to read in terms of both their mood and combat movements. New Morganite remarks that "not knowing what Nepti is saying is part of their charm".
