This is half of a small azurite geode. The azurite appears to have lined a cavity in a host rock, with crystals lining the interior. The bulk of the material is a medium blue without crystal form, and the cavity in the center of the geode is coated with a druze of deep blue azurite crystals. A radial pattern is apparent, and some of the azurite (primarily a layer between the exterior and the inside crystals) has partially converted to malachite.
