In Steven Universe, fusions that are partially made from quartz gems (like Opal) can technically count as at least being part-Quartz, since Amethyst's gem serves as one-half of Opal's body and consciousness. It is never stated that the gems of the fusion transmute into their namesake (like it is never said that Pearl's gem actually turns into an opal gemstone when she becomes Opal). Sardonyx (in context with the show) is technically not a Quartz gem herself since Pearl, Ruby and Sapphire - the gems that make her up - are also not Quartz gems.
