When Jordi offered me a corner on his web page to publish photos of the pieces that I choose I found it an excellent idea. It goes without saying that the project made me very enthusiastic immediately.

It is my intention to show, through my photographs, my point of view of the beauty of minerals, and I hope to add to that a point of charm, that touch of magic that minerals awaken in all those who view them with delight and admiration.

TMA70AN8
Cuprite crystals formed by the dominant octahedron and cube, beveled by rhombic-dodecahedron faces, with some window growths and with very well defined faces and edges. The crystals, on a rock matrix, are translucent and have a very deep red color, partially masked by their extraordinary luster.

Botryoidal growths of small rhombohedral Rhodochrosite crystals, with very good luster and an a vivid and uniform pink color, covering a botryoidal Hisingerite-Neotocite (Series) matrix. It should be noted that there is a second generation of smaller Hisingerites dotting the botryoidal Rhodochrosite crystals.

NBA26AN8
Cubic crystals of Fluorite beveled by the rhombo-dodecahedron, translucent and with an intense bluish lilac color, on a Quartz crystal dotted with small cream-colored crystals of Siderite with hexagonal contour, both on the Quartz crystal and on the Fluorite crystals, a fact that shows that a carbonate, in this case Siderite, was the last mineral to form. Different.

Group of complex equant crystals of Sphalerite, very transparent and lustrous, with an intense color and a lively interior "fire". Large for the deposit and on a matrix of lenticular crystals of Siderite with a very light cream color, and twinned Bournonite crystals.

MTA91AN8
Group of sharp Anhydrite crystals in parallel growth, with sharp crystal forms and excellent terminations, between transparent and translucent, with good luster and an intense violet color under artificial light and a flesh color with natural light. They are accompanied by small, completely transparent crystals of Celestine on the front of the specimen. A German classic from an old iron mine.

MRM73AN8
Twinned Bournonite crystal, isolated, very aerial and large, shiny and on matrix, with complex Pyrite crystals, twinned Sphalerite crystals and small white Calcite crystals. This specimen, from a recent find, recalls the classic bournonites found in the mine in the past. It has been tested that the Bournonite crystal was not mechanically bound to the matrix, corroborating the nature of the specimen.
