5.2" Banded Blue Lace Agate Slab - Sanje, Malawi

This is a beautiful 5.2" wide slice of blue lace agate from Sanje, Malawi. It features exceptionally vibrant, sky-blue coloration with delicate, flowing bands of chalcedony that create an intricate, lace-like pattern.

Blue lace agate forms through the gradual deposition of silica-rich hydrothermal fluids within fractures and cavities in the surrounding rock. Over time, successive layers of chalcedony build up to produce the distinctive banding and soft blue hues that make this variety of agate so desirable.
