Blue Aragonite: A Little Copper Goes a Very Long Way

by Laura Konst
Blue Aragonite is calcium carbonate coloured by trace copper, the same ion that produces the deep blue of Azurite and the green of Malachite, but in a very different structural context and at a fraction of the concentration. This guide covers the colour mechanism, the Aragonite-Calcite polymorph relationship, how Blue Aragonite compares to other blue carbonate minerals, and why its care requirements are more specific than most.
