Montmorillonite Ventura County, California, USA Dimensions: 2.8 × 2.6 × 2.2 cm and 2.9 × 2.3 × 1.4 cm
A pair of older California Montmorillonite specimens showing the mineral as compact, very pale cream to ivory masses with subtle pinkish-beige tones.

An interesting locality pair from an older collection, preserved together with their original catalog label.
