Geodes, spherical formations that look like ordinary rocks on the outside, but when sliced open they reveal another world within. Hollow orbs, interior walls lined with crystals projecting toward the center. They exist in all sizes, shapes and colors. Tiny ones found in Tabasco Mexico make great earrings.
The walls of these crystal pockets are sometimes banded, revealing differences in the chemical composition of groundwater that leaked into the cavities of bedrock over time as the geodes formed. You never know what you will find until you cut it open.
Otherworldly? Maybe not. But when you wear these sliced geodes, one in each ear, the many faceted crystals catch the sunlight and sparkle and glitter like so many stars in the night sky. You might just find your energy aligning more with star energy, and astral travel may become more accessible to you.
