I. The Metaphysical Reading
How the stone has been held.
Blue smithsonite is worked with as a stone of tender recovery, particularly after long strain of the throat, chest or heart. Practitioners hold it during quiet convalescence and speak of its rounded surfaces as a reminder that healing rarely arrives in straight lines.

II. The Scientific Reading
What the lattice actually does.
Blue smithsonite is zinc carbonate whose colour comes from trace copper substituting into the trigonal lattice. The classic sky-blue botryoidal material was mined from the Kelly Mine in Magdalena, New Mexico, worked from the 1860s until the deposit was effectively exhausted in the 1930s, making original Kelly specimens highly collectible. Modern production comes from the Tsumeb district of Namibia and from Lavrion in Greece.
