Goethite with Calcite and Pyrite.
TM61Y7: Goethite with Calcite and Pyrite
Very well defined botryoidal, almost spheroidal, growths of grayish black Goethite with transparent Calcite crystals, with small cubic Pyrite crystals, and on matrix. The Goethite has been analyzed and we’ll send a copy of the analysis to the buyer. We regret we can not provide more precise details about the locality but, as frequently happens with Chinese material, the origin remains unknown.

Goethite with Conichalcite.
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.
The specimen's photo has been reviewed and published in the magazine ‘Rocks & Minerals’ on page 555 in the volume 90, number 6, Nov/Dec 2015

Goethite with Quartz.
JFD34AN7: Goethite with Quartz
Beautiful iridescent goethites appear not only in Huelva, but also in Murcia, in the famous San Valentín Quarry. They can be very beautiful, like this one that covers Quartz crystals and in which an elongated botryoidal group seems to form a narrow bridge over the Goethite itself. From Alain Martaud's collection, I liked it when I bought it from him because it was so elegant and original.

NJ58K8: Iridescent Goethite
Stalactitic-botryoidal growth with intense iridescence, very bright, metallic reflections, whose dominant colors vary between red, blue and gold.

Iridescent Goethite.
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. Also, a highlight is the pale pastel color iridescence, whose colors vary between green, deep blue to slight pink, and gray reflections with ocher zones.
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.

Quartz with Goethite inclusions.
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.
