Mineral specimens search results for [ goethite ]

Black botryoidal growth of Goethite, lustrous, and with a second generation of Goethite in fine columnar and arched forms. Goethite is a rare species in this mine, much better known for its Pyrolusites and other manganese oxides.

Specimen size: 10.1 × 8.2 × 1 cm = 3.98” × 3.23” × 0.39”

NK6S8: Iridescent Goethite

The iridescent Goethite from Rio Tinto is different from the Tharsis iridescent Goethite, it is not stalactitic and is much more colorful.
From an old find at the classic Rio Tinto mine, this Goethite surprises us with its rich and varied colors.
Cerro Colorado Mine, Rio Tinto Mines, Minas de Riotinto, Comarca Cuenca Minera, Huelva, Andalusia Spain (±1985)
Specimen size: 11.5 × 8.7 × 5.5 cm = 4.53” × 3.43” × 2.17”

TC80NZ: Goethite

Botryoidal and stalactitic Goethite growths with variegated metallic iridescence of dominant reddish and gray tones. The specimen comes from a famous find in 2007.
Filón Sur open pit, Minas de Tharsis, Tharsis, Alosno, Comarca El Andévalo, Huelva, Andalusia Spain (05-10/2007)

SV3220EPP: Goethite

Although not very famous, the Haiti mine has also yielded botryoidal goethites, sometimes of good quality. This specimen is a perfect example of this, with the Goethite/matrix relationship well balanced, with slight iridescence and a lot of luster in the Goethite groupings. It was in the collection of Miguel David Martínez with number 1818 and we will send its label to the buyer of the specimen.
Haití Mine, Cabezo de San Ginés, San Ginés de la Jara, Cartagena, Comarca Campo de Cartagena, Region of Murcia (Murcia) Spain (2016)
Specimen size: 11.4 × 8 × 5.7 cm = 4.49” × 3.15” × 2.24”

9FL26Z9: Goethite

Aerial botryoidal and stalactitic growths of Goethite with ferruginous iridescence dominated by green and reddish tones. The specimen comes from a one-time find in a mine on land with no current access, so there will be no new specimens in the foreseeable future. The La Lapilla deposit is known for its gossan rich in metals, especially Gold, but it is difficult nowadays to find quality Goethite specimens from there on the market
La Lapilla Mine, La Lapilla, Alosno, Comarca El Andévalo, Huelva, Andalusia Spain (03-04/2008)
Specimen size: 9.8 × 3.7 × 2.6 cm = 3.86” × 1.46” × 1.02”

TP56AM9: Goethite

SV3140TPZ: Goethite coating Siderite

A brilliant piece. The Siderite specimens from this forgotten locality were once a subject of debate because their appearance resembled Goethite. However, this is actually due to the presence of Goethite, which forms a thin layer covering the outer part of the Siderite “stalactites”! As is often the case, mineral collection and preservation prove to be valuable to the field of mineralogy.
Mina Peyreblanque, Alban, Albi, Tarn, Occitanie France
Specimen size: 7.4 × 4.6 × 3.8 cm = 2.91” × 1.81” × 1.50”

Main crystal size: 0.3 × 0.1 cm = 0.12” × 0.04”

FE14Z8: Goethite with Azurite and Malachite

Botryoidal Goethite aggregates with a metallic iridescence and aggregates of small lenticular Azurite crystals and velvety aggregates of acicular Malachite crystals. We especially note the locality, now extinct, and the association of Malachite and Azurite with the Goethite.

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.
China (2007)
Specimen size: 9.6 × 9.2 × 3.5 cm = 3.78” × 3.62” × 1.38”

SM220NAA: Goethite

Specimen size: 10.2 × 8.7 × 3.3 cm = 4.02” × 3.43” × 1.30”

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.
