Geode
A geode is a rock cavity whose inner walls are lined with crystals, formed over millennia by underground waters rich in dissolved minerals. The best known are the amethyst geodes of Brazil and Uruguay, sometimes as tall as a person. In lithotherapy, tradition treats it as a centerpiece, set in a living space for its presence, and as a natural support for recharging other stones.
How it forms
It all starts with an empty space: a gas bubble in cooling lava, a pocket hollowed out of limestone. Over thousands of years, silica-laden waters move through it and lay down their crystals layer by layer, from the wall toward the center. When the rock is opened, you find this inner sky: a hollow turned into a jewel case.
At home
A geode lives as a centerpiece: set in the living room or near the entrance, it draws the eye and settles a presence into the space. Tradition also gives it a charging role, so rest your tumbled stones or jewelry in its hollow overnight. And every now and then, dust it with a soft brush, since its points dislike both knocks and rubbing.
