Shattuckite, El Jacolito Mine, Cuitaca, Sanya Cruz Municipality, Sonora, Mexico
A beautiful thumbnail featuring spherulitic aggregates comprised of acicular and fibrous, light to dark blue Shattuckite crystals with a silky lustre. The white mineral is most likely Plancheite. The El Jacolito Mine is a fairly recent find (2019-2020), approximately 20 km east of the Milpillas Mine, on a privately owned ranch.
