Other Geodes

What are geodes?
A geode is a partially hollow, globe-shaped tubercle that is covered with crystals on the inside. They formed as gas bubbles in the liquid magma that rose in a crater pipe during an eruption of a volcanic eruption. These gas-filled bubbles persisted after the magma solidified and filled with saturated mineral solutions. This allowed beautiful crystals to form.

The geodes are thus often found in volcanic areas. The geodes can be very small or very large. You can see this particularly well with Amethyst from Uruguay or Brazil. The geodes are usually cut in half and cracked with special pliers. The saw cut is often polished.

In this category you will find the following geodes:
Agate geode
Rock crystal geode
Calcite geode
