Goethite, incredibly iridescent and colorful, has a botryoidal shape on the surface that reflects a multitude of colors. An extraordinarily colorful and beautiful form of a mineral characteristic of the Tharsis mines (Huelva, Spain), in which all types of metallic and botroid tones predominate.

Beautiful sample of this silicate from the Cantera de Ofita in Calpe, Alicante, Spain; this group of granular analcimated crystals, with forms that are usually between trapezohedral and icositetrahedral crystals, of a brightness between colorless and white, and vitreous with a transparency between opaque and translucent, represent the type of pieces that occur in this area of Valencia, a very suggestive mineral.

Beautiful piece and aesthetic of goethite with stalactitic morphology from the Riotinto mines. Atypical piece of this mine.

Beautiful crystalline celestine mineral aggregate from a town that is impossible to enter today, surrounded by security and with the deposit almost exhausted, it is a monolithic piece, difficult to find today. Very shiny and with an overlapping and very stepped prismatic pattern, shiny and very well finished, with well-defined crystals. A super aesthetic piece.

Wonderful piece from the "Cerro Negro" quarry in Quesa, Valencia, Spain, where you can see a beautiful aggregate of acicular aragonite crystals with a random arrangement of its crystals. Spectacular specimen of acicular aragonite. Methacrylate base included.

Sphalerite & Quartz

Jose Maestre Tunnel, Portman, Sierra de Cartagena, Murcia, Spain

[adraelfineminerals]

Malachite of green color and acicular morphology in bouquets on aggregates of bright Azurite crystals which in turn are on a limonite/goethite matrix. Really aesthetic piece with an intense blue and green color. Great contrast with the matrix making it a very attractive item.

[adraelfineminerals]

Classic sample of cinnabar crystals from the “Las Cuevas” mine, they are of an intense red color, very vivid and brilliant of gem quality on matrix.

[adraelfineminerals]

Very lustrous and aesthetic hematite specimen exfoliated into flakes of great black metallic shine. Crystalline aggregate from the Oriolet quarries.

[adraelfineminerals]

Beautiful combination of minerals from the municipality of Lebrija, Seville, on an ophite matrix; In this matrix we observe yellowish titanite crystals, we see crystallizations of whitish albite, orange orthoclase, fan-shaped prehnite and dark-toned acicular crystals of ferro-actinolite. A very complete specimen minerally speaking.

[adraelfineminerals]

Beautiful aggregate of calcite crystals on a limonite and goethite matrix from the "Trinidad" iron mine (Benalmádena, Andalusia, Spain). Calcite crystals are very bright, have a slight yellowish hue due to the influence of oxides and contrast with the matrix that contains them. The crystals are finished and rare to find, it is a piece to consider.

[adraelfineminerals]

Spectacular and rare group of very well defined pyromorphite prismatic crystals with a hexagonal section, on matrix, that have an attractive light brown to opaque green color, typical of the locality of Santa Eufemia in Córdoba (Spain), where few specimens are found due to its difficulty and rarity. Great piece from a mine that barely produces quality specimens.

Coming from the Bouvesse quarry and on a limestone matrix comes this specimen in which we appreciate crystallizations of celestine with a vitreous luster mixed with crystallizations of transparent, super-bright calcite, with scalenohedral morphology, with well-defined faces and edges. Among the dominant minerals we see twins of Pyrite crystallizations with a very aesthetic metallic luster.

[adraelfineminerals]

Specimen of calcite crystals on matrix from the "Herculano" mine, with a beautiful vitreous luster and a quite particular crystallization associated with this Spanish deposit now closed.

In a quarry (quarry "La Tinaja") where clay is extracted to produce ceramic pieces, acicular and starry aragonites are obtained with needle-shaped, radiated, high-gloss and high-transparency crystals that take the name of the municipality where they are located, they are called aragonites "Pantoja", specimens difficult to find in other places and that, due to their shape and uniqueness, are highly appreciated by mineral collectors. Delivered in a methacrylate box.

[adraelfineminerals]

Beautiful aggregate of cubic Fluorite crystals, transparent, beveled, well defined, pale in color, but very bright that form a piece of spectacular beauty that was found in the so-called "Corta La Sirena". A beautiful specimen.

This radioactive specimen comes from the Mine called “Diéresis” with a matrix of Orthoclase and smoky quartz on which crystallizations of Uranocircite are housed with intense fluorescence in the presence of UV light. Radioactive piece.
