Specimen
A false hexagon, honestly made.
Aragonite Star Cluster
Rust-orange prisms that grew outward from a shared center in every direction at once. Three crystals repeatedly intergrow at sixty degrees here, which fakes a six-sided shape from a mineral that is really orthorhombic. It is softer than quartz and will fizz in acid.
$5
Three clusters together, $12.
