Some of the most well known minerals in this category include Magnesite, malachite, molybdenite, moonstone, obsidian*, opal*, prehnite, pyrite, and pyromorphite.

I have been perhaps a little cheeky here. Obsidian and Opal are not minerals, but mineraloids; they do not have distinct crystalline structure and would not fulfill the category of minerals.
