Please note that posts on this site may contain affiliate links

Sea glass is a beloved treasure of the sea witch. Found along shorelines around the world, this special glass is formed when pieces of human-made glass end up in the ocean and are worn smooth by years of tumbling in the waves. The frosted, soft texture and luminous colors of sea glass lend it beautifully to magical work.

What is Sea Glass?

Sea glass begins its life as man-made glass – usually discarded or lost fragments of glass bottles, vases, cups, plates, windows and other objects. Over many years of wave action, the sharp edges are worn down and rounded out, and a lovely frosted texture develops. The original clear glass becomes saturated with minerals and takes on soft pastel hues like blue, green, white, brown, peach or pink.

In magical practice, sea glass picks up the healing and transformative energies of the ocean. Its water-smoothed nature provides the energies of calm, clarity, flow and change. The colors also add their own properties – blue for psychic abilities and healing, green for prosperity and growth, white for purification and clarity, and so on.
