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.

Pyrite.

TE37AI9
A floater group of pyritohedral crystals without minor forms, with very well-defined faces and edges, very bright and partially coated by growths of calcite microcrystals. The specimen is from a locality where good Pyrite specimens are not so common.

Concepción del Oro, Municipio Concepción del Oro, Zacatecas
Mexico


Calcite fluorescent long & short UV

Specimen size: 7.5 × 6.2 × 3.7 cm = 3.0” × 2.4” × 1.5”

Main crystal size: 1.4 × 1.2 cm = 0.6” × 0.5”

Specimen size: 6.2 × 5.4 × 2.6 cm = 2.4” × 2.1” × 1.0”

Main crystal size: 1 × 0.3 cm = 0.4” × 0.1”

Brochantite. Brochantite.

TR88AI9
Brochantite specimens from Milpillas have won a well-deserved fame for their excellent quality. In this case, the idiomorphic crystals are elongated,with sharp faces and edges and a very deep green color; the matrix is partially coated by a later generation of brochantite, showing pale green fibrous crystals with satiny luster. In my opinion this locality offers the world’s best Brochantite as judged by crystal size and sharpness, deep color and high luster.

TL62AI9
Brochantite crystals from Milpillas are famous for their sharpness and generally excellent quality. Here we have a group of idiomorphic Brochantite crystals with well-defined faces and edges and chisel-like terminations. The specimen’s composition, with large crystals on matrix coated by smaller crystals, makes for fine aesthetics. In my opinion this locality produces the world’s finest Brochantite specimens.

Volborthite. Volborthite.

EK57AI9
Milpillas Volborthite specimens are without doubt the world’s best: with their large crystal size and high luster they set a new standard for this rare species. This small specimen shows a rosette-shaped growth of flattened Volborthite crystals on matrix; the rosette is very sharp and deeply colored.

HD14AI9
This specimen represents a classic Italian locality for Ilvaite. It is one of the better known localities for the species, but only a very small number of specimens from it have ever been recovered and saved. The Ilvaite crystals, some terminated sharply on one end and less sharply on the other end, are highly lustrous. Small quartz crystals are associated.

FF71AI9
An aesthetic group of octahedral Fluorite crystals with polycrystalline growths on the edges. The translucent Fluorite crystals have a very deep violet color, and they share their matrix with cubic Pyrite crystals and small Quartz crystals. The specimen is from a mine which went extinct many years ago.
