- Siderite, Calcite
- Small Cabinet, 8.0 x 6.8 x 4.1 cm
- Ojuela Mine, Mapimi, Mun. de Mapimi, Durango, Mexico
A HIGHLY UNUSUAL and showy, old-time specimen from the famous Mina Ojuela of ultra-sparkly siderite microcrystals festooned on a sculpturally shaped box-work matrix of bladed calcite crystals. I have never seen another Mina Ojuela siderite remotely approaching this one. Ex. George Elling Collection.
