Cobalt Calcite
Deep pink softness for the heart.
Cobalt calcite is a deep pink to magenta calcium carbonate mineral colored by trace cobalt atoms woven into its crystal structure. The most vivid commercial material comes from Katanga Province in the Democratic Republic of the Congo, where cobalt-rich deposits produce botryoidal clusters and small crystal forms.

The DRC sourcing context carries ethical weight, and we own that openly.
