Grandidierite characteristically forms in translucent bluish green or greenish blue, elongated crystals but is rarely very clean.
Although cab and mineral quality stones are not uncommon, clean facet quality stones still are almost unknown. Until 2014, a single .29 carat stone from Sri Lanka was apparently the only reported facet quality stone.
