Epidote Geode

Epidote geodes contain usually dark, olive green colored crystals. Uncovering one is like discovering a secret patch of moss or leaves, with each one showing off shades of green that seem to whisper of ancient woods.

Epidote often grows where there are changes in temperature and pressure. As rocks change and shift, the right conditions are made for them to form.

Its name comes from the Greek word ‘epidosis,’ which means ‘increase.’ It’s because the mineral’s crystal faces often have one side longer than the other, making it look like it’s growing or increasing.

What makes epidote geodes so distinct is their color and the way the crystals group together. They often grow in long, thin shapes that cluster like a bunch of needles or blades. This unique appearance is one reason why they’re so valued.

Where you can find epidote geode

Epidote geodes are usually found in places that have a lot of activity under the ground, like where tectonic plates meet. This means they’re often discovered in mountain ranges and areas with lots of old, changing rocks.

Countries like Norway, Austria, and the USA, especially in Alaska, are known for their beautiful epidote specimens.

Hematite Geode

Hematite geodes are like holding a piece of the night sky in your hands, with their shiny, metallic surface that reflects light like stars.

The crystal hematite starts with iron-rich water seeping into the ground. As it moves and reacts with oxygen, it leaves behind the iron, which slowly turns into hematite.

The value of hematite geode comes from its crystals’ striking appearance and history. Its shiny surface has drawn people for centuries, so it’s used in jewelry, as a pigment for paint, and even for protection in battle.

The dark, metallic color of hematite is so unique, it’s been a symbol of strength and courage for a long time. Not only that— it’s the main ore of iron, which means it’s where most of the iron we use comes from.
