About the stone

Blue lace agate is a variety of chalcedony prized for its delicate, wavy bands of pale blue and white. Its modern commercial history began in the early 1960s at Ysterputs in southern Namibia, its principal source; discovery accounts differ, with some crediting prospector Willy Preiss and others George Swanson, who developed and internationally promoted the deposit. Similar material occurs elsewhere, including South Africa, although Namibia supplies the classic, finely banded stone. Swanson marketed it as the “Gem of Ecology” because its patterns resembled Earth and clouds viewed from space. In modern crystal lore, it symbolizes peaceful communication, emotional calm, and harmony.

Care and handling

Blue Lace Agate is a hard, durable chalcedony, but fine banded or geode pieces can be delicate at their edges and druzy centers. Clean it with lukewarm water, mild soap and a soft cloth, then dry it. Avoid sudden temperature changes, harsh chemicals and heavy knocks.

Individual experiences with Blue Lace Agate vary. Use it mindfully as a gentle companion for clear and compassionate speech.
