Demantoid and Topazolite belong to the Garnet Supergroup, specifically to Andradite, and are thus an iron/calcium silicate with a cubic crystal structure. The green to olive-green crystals of Demantoid get their color from traces of chromium, while iron is responsible for the brown or yellow color of Topazolite. Mixed crystals exist in between. Andradites have a medium hardness (Mohs 6-7.5).
