Blue Aventurine is a variety of quartz that contains inclusions of minerals such as dumortierite or crocidolite, which give it its characteristic blue color. Like other quartz varieties, it forms when silica-rich fluids slowly crystallize within cracks and cavities in surrounding rock over long periods of time.
