It was part of the pierres précieuses (fr.: gemstones) program, that included five prototypes Agathe, Topaze, Emeraude, Rubis and Saphir, leading up to the Diamant orbital rocket.
Its codename, VE210, indicates that it is a "Véhicule Expérimental" (Experimental Vehicle) with 2 stages, using solid propellant (code 1), and not guided (code 0).
The rocket was used to test technologies used in the Diamant, as well as to launch scientific instruments from the Paris Observatory and Max Planck Institute.
Description
Rubis used an NA801 Mammouth engine (similar to Agate) for its first stage and a P064 engine for its second stage.
