One of my 2 cases at the recent 2018 Cincinnati show. The show theme for minerals was calcite and its many crystal forms.

Two examples of Aragonite sprays on Quartz with some corroding iron oxides (limonite). Both self collected about 10 years ago.

Two more examples of Indiana Millerite from my collection. Both were self-collected about 2007.

One of the so called hallmarks of the rock structure called a quartz geode is that the quartz crystal tips are suppose to point inward toward the center of the cavity. While this is generally true, a very small percentage have other appearances. These are a few; all self collected.

 Dimensions: Both are about 9 cm

Both examples have interesting free form quartz areas within the cavity.
