One geode was crystal-filled. The other was solid.
Why do geodes form so differently?
Our latest blog explains why some stay hollow while others gradually fill with minerals over millions of years.

🔁 🔥 Quick Bits - Biomineralization
is the process by which living organisms produce minerals, often to form hard structures like bones, shells, or teeth.
It involves the controlled deposition of minerals (e.g., calcium carbonate, silica) within organic matrices, guided by biological molecules like proteins or enzymes.
Organisms regulate crystal growth, shape, and orientation to create functional structures.
❤️ 🔁 How process is used in Industry
Biomaterials: Mimicking biomineralization to create biocompatible materials for medical implants, bone grafts, or dental restorations.
Construction: Bio-inspired cements and concretes that self-heal or sequester CO2, inspired by microbial carbonate precipitation.
Nanotechnology: Using biomineralization principles to synthesize nanoparticles or coatings with precise structures for electronics or drug delivery.
Environmental: Bioremediation uses microbes to precipitate minerals, aiding in heavy metal removal or carbon capture.

So, I feel Hazel would go absolutely feral if she were ever shown not only a giant geode, but could peek inside without having to smash it open completely. I know I probably would.

🔁 Unlocking the Hidden Splendor of Geodes: Nature’s Secret Vaults
▶️ Ever cracked open a plain rock to reveal a dazzling crystal chamber?
Geodes, nature’s geological treasures, conceal vibrant crystals within their unassuming exteriors, waiting to captivate explorers and scientists alike.
Formation Story
Geodes are spherical or subspherical rock structures, typically ranging from a few centimeters to over a meter in diameter, found in sedimentary and volcanic rocks worldwide.
Formed over millions of years
they begin as cavities within rock, often created by gas bubbles in volcanic lava or dissolved organic material in sedimentary layers.
Groundwater
rich in dissolved minerals, such as silica, calcite, or amethyst, seeps into these cavities, depositing crystals layer by layer.
In regions like Brazil
Uruguay, or the American Midwest, geodes are prized for their stunning interiors, revealing quartz, amethyst, or calcite crystals that shimmer in vibrant hues.
Geological Information
Geodes form primarily in two geological settings: volcanic and sedimentary environments.
In volcanic settings
such as the basalt flows of Brazil’s Rio Grande do Sul, gas bubbles trapped in cooling lava create vesicles that serve as cavities for crystal growth.
In sedimentary environments
like the limestone and dolomite beds of Iowa’s Keokuk Formation, cavities form from the dissolution of organic material or nodules, later filled by mineral-rich fluids.
The process begins
with silica-rich groundwater precipitating chalcedony or quartz, forming a durable outer shell.
Subsequent mineral deposition
influenced by changes in temperature, pressure, and fluid chemistry, creates crystalline interiors.
The crystal type
quartz, amethyst, or calcite, depends on the mineral content of the infiltrating fluids and local geological conditions.
For example
amethyst geodes in Uruguay owe their purple hue to iron impurities.
Formation can take millions of years
with some geodes dated to the Permian period (250 million years ago).
Recent studies
highlight the role of tectonic activity and groundwater flow in controlling mineral deposition rates, making geodes a window into ancient environmental conditions.
▶️ Interesting Fact
Some of the largest geodes, like those in Mexico’s Naica Mine, are so massive they form walk-in crystal caves, with selenite crystals reaching up to 12 meters long.
These “super-geodes”
are rare and form under extreme geothermal conditions, offering a glimpse into Earth’s hidden wonders.

Anyone know what kind of crystal my 8YO found?
@PatriotNana23 No, the confusion is thinking God is a person. The God of human doctrine is nowhere to be found. You’re asking for proof of what doesn’t need proven, and can’t prove your own precious beliefs. Why not go before Congress to prove Catholicism?

The word hybrid wouldn't be used to describe a Soul, which is who we truly are. The modern physical human form wouldn't exist without intervention by positive ETs, with some genetic alterations from negative ETs much later. There were outside influences which at this point might as well be called "human", so the word hybrid is unnecessary.
