Miniature, 4.6 x 3.4 x 2.9 cm
Santa Eulalia District, Mun. de Aquiles Serdan, Chihuahua, Mexico
Siderite can be a pretty boring mineral, usually seen as just an "accessory" mineral on specimens of something else. But in this case, it has formed a truly striking and aesthetic specimen! It features four intergrown sparkly balls, with a surface of small crystal blades. It is a floater, with no attachments. Santa Eulalia is known for many fine collector specimens, but you do not see many of these around!
