Two generations of vanadinite crystals. A good-sized brilliant crystals, with echeloned growths and defined faces and edges. With good color yellow and peppered by deep black coronadite globular aggregates. Another generation shows small crystals (<1 mm) but with a nice luster, transparence, and yellowish tone. Both are on a matrix of goethite.

In this excellent specimen we can observe different vanadinite crystals phases. The first is formed by botryoidal aggregates of small vanadinite crystals. Brilliant, translucent and with a yellow to greenish tones. On a second generation, we have huge size and brilliant crystals, with yellow to orange color, which show rounded faces and edges, one of them having a drop shape. One of the cavities of the goethite matrix is covered by very sharp and brilliant lanceolated prismatic crystals of mottramite. Also accompanied bybotryoidal coronadite. Novelty in SMM-2012.

A group of very curious yellowish vanadinite hexagonal crystals disposed on a layer of botryoidal coronadite acicular aggregates which are covering the goethite vugs. Accompanied by small but defined mottramite crystals forming clusters partially covering vanadinite crystals. They show a honey to brown color and dipyramidal faces and skeletal growths. A nice sample to be enjoyed on the display and under the microscope.
