I have a large amethyst crystal chunk that’s nearly the same height as my male dragon….I’ve got smaller pieces of malachite, unpolished ammonites in matrix, citrine, agate, moss agate, a large tabular piece of flourite, geode….I’ve actually got several agate specimens…a split and polished 4 inch black moroccan ammonite with chamber crystals…um, there’s probably more but my mind just blanked…
