Sourced from Nsanje, Malawi, these selected cleaned blue lace agate specimens form in the cavities of volcanic basalt rocks. The distinctive blue color results from the Tyndall effect—light scattering by colloid-sized particles within the chalcedony. The intricate banding or lacy patterns develop from the deposition of silica-rich fluids in fine layers over time. Colors and patterns vary based on specific mineral content, impurities, and conditions during the formation process, with banding resulting from alternating layers of different compositions.
Mineral: Blue Lace Agate (Blue Chalcedony)
