Siderite ps. After Calcite (rare) Tom Wolfe Coll.

Item Description

Sparkly, gemmy, golden-brown siderite microcrystal rhomb epimorphs have casted a scuptural and aesthetic 360-degree cluster of dogtooth calcite crystals from the La Sirena Mine at famed Guanajuato. The scattered patches of contrasting quartz points are a nice contrast. The hollows on the bottom are impressive in their form. Siderite is an uncommon accessory mineral from this mine and this is a very fine example. Ex Tom Wolfe Calcite Collection.
