Description

Very aesthetic piece with a large, lustrous siderite crystal of textbook form, associated with two quartz points! The quartz points are also lustrous, with nice patterns on the termination! There is only one ding on the side of the termination of the biggest quartz point, not seen on the display face and a broken quartz on the back. The bottom is terminated, as well. Please consider that most pieces from the mine are in too bad condition and pieces like this are considered pristine.
