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

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.

Two unusual examples from my collection.

The first is a 15 cm x 15 cm geode showing a double cavity layer of druzy crystalline quartz tips atop blue-gray microcrystalline quartz (chalcedony).

The second example is an 11 cm x 7 cm oval and bi-septate geode with one cavity showing blue-gray microcrystalline quartz (chalcedony), while the adjacent cavity contains druzy clear quartz crystal tips.

As I understand crystal formation as related to crystal size, the faster the crystal forms, the smaller the crystal might be. So the formation of microcrystalline quartz (chalcedony) implies rapid formation. Interesting how this bi-septate example might have formed. BOB

From Washington County Indiana come the largest geodes, not only in Indiana, but probably in the US Midwest. Also found are many large colorful and very photogenic examples with collectible calcites. I have shown several in previous posts and here are 2 more. BOB

Many geodes that, when opened, happen to break badly, can still be salvaged. Very collectible areas can be culled from the broken examples. These are 2 more such examples. Calcite on Quartz and Calcite on Dolomite.

Rather than being a "geode" the examples now become more traditional "specimens". BOB

Collected about 20 years ago, acquired by me about 10 years ago, with the quarry closing and becoming flooded about 5 years ago, this is now a classic from this now extinct locality.

Examples of this quality, from this locality, are only rarely seen now-a-days. Culled out examples of larger doubly terminated Celestine crystals on Quartz with the limestone matrix are a true rarity.

A large piece of coarsely grained fossiliferous limestone with a 3 cm Quartz geode of little significance except for the incidental nearby occurrence of a 5 cm vug containing sprays of Aragonite. Self collected about 12 years ago.

Great finds! I wish I lived in a location where I could collect myself. The closest destination, that is decent, is three hours away and only accessible during low tides. The only stores that sell minerals are in the same location, as is the yearly show I attend lol.
