NE9M1: Iridescent Goethite

If the Tharsis Goethite samples are well known for their intense colors and defined stalactitic growths, La Lapilla Goethite specimens stand out because of their delicate crossed stalactitic growths and filament-like structures.

La Lapilla Mine is well known by the rich base metals “gossan”, above all its high Gold content, but is not so known for Goethites.

N16RE6: Quartz with Goethite inclusions

I will get sentimental about this one. While it is not a top quality specimen (I don’t want to fool anyone into thinking it is) it was one of the first that I added to my own collection. Recently I got a better example, so I have decided to sell this one - with the original label from my collection: number F-33. I bought it during a trip to Morocco with my brother in 1974, when I did not even know what the mineral included in the Quartz was. The great collector from Barcelona, Joaquín Folch, told me that, based on the pleiocrism, they are crystals of Goethite. Anyway, apart from the history, I have always liked this one and I still think that the spray of Baryte and blobs of Quartz at the rear make it neat. As you would expect, we will send my label to the person that buys this.
Tizirine, Ouarzazate Province, Souss-Massa-Drâa Region Morocco (1974)
