Rockface

A manly cologne manufactured by Ellings Cosmetics, and mostly seen on Nix.

The spray contains a mixture of a "Rough, masculine" fragrance (which is vaguely reminiscent of the residue on a man's skin after working in the diamond mines), and powdered diamond and sapphire, produced from the low-grade stones and drilling residue that several mines can't sell. This gives the wearer's skin a slight sparkle in strong light, making it very popular among upper-class Nixin.
