18CBR09: Goethite after Marcasite

Crystals with well defined faces and edges that show "sperkise" twinning, with polycrystalline growths on some of the faces, and that have been totally pseudomorphed by brown Goethite.

EM16Z5: Goethite with Conichalcite

Small acicular Goethite crystals, very bright and with reddish reflections due to its pleochroism. They are on a matrix with Quartz crystals, some of them doubly terminated, and with small botryoidal Conichalcite aggregates. Different than most of the usual samples from the Bou Azzer area.

SV3390EXL: Goethite coating Quartz

A great piece from the San Valentín Quarry. The Quartz crystals are of good size, the Goethite that covers them has intense iridescence and the whole thing has a strange beauty. There is a slight saw cut on the back that barely impacts the visual appearance of the specimen. This piece was in one of the great collections of that area, that of Mariano Guillén. His collection passed to that of Miguel David Martínez with the number 1700 and whose label we will send to the buyer of the specimen.

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 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.

JFD35AN7: Goethite

The La Lapilla goethites have an 'architectural' point and, although their color is sometimes not as intense as that of the Tharsis goethites, their structure and the design of their formations have always attracted me. I got it (of course) from Fermín Clemente, a great field collector in the Huelva area.
