This sigil refers to a round crystal with concave shallow pits over its surface, this form is a kind of storage media. (Same was used above)
This one in particular contains information for the initiation of a popular witchery group, which will go by the name of (witch) Rites, to be read both as a practice and as the right to practice.
While Coven contains the elitist practices, Rites will gather the thinned out, common practices. But make no mistake, only the form differs. Rites are just as powerful as Coven magic, it is just less esoteric and less reliant on the individuals' own skill. It is a collectivized method.
