In this small specimen we can see several well-formed cinnabar crystals, bright and transparent, with an intense colour. They are dotted with small rhombohedrons of dolomite, with quartz and pyrite. A very aesthetic miniature.

On the compact quartzite there is a druse of small hyaline quartz crystals, on which various cinnabar crystals have grown. As they are fissure crystals, the largest ones appear flattened, but shiny and with red transparencies. With small drops of liquid mercury.

Almadén cinnabar specimens are well appreciated worldwide. In this specimen we want to highlight the numerous drops of mercury that are deposited (without falling) on the cinnabar and the matrix rock. Also noteworthy are the numerous cinnabar crystals, transparent and defined, with a very intense vermilion color.

White globular aggregates of thomsonite-Ca, on the basaltic matrix. Excol. M. Marín de Castelló. A classic specimen of Spanish mineralogy.

Rich group of small pyromorphite crystals, prismatic, hexagonal and truncated by pinacoidal faces. Good color and shine. Examples of this mine are not easy to come by today. The sample is accompanied by the handwritten label of Joan Viñals.

This is a representative specimen of fissural cinnabar, in which we can observe under magnification small flattened cinnabar crystals, with striated faces, on a druse of quartz crystals. The transparence makes it very brilliant under the light.

A historical specimen of this classic mine. Various tabular baryte crystals peppered by small but brilliant and well-shaped cinnabar crystals. These specimens are very difficult to find today.

This specimen is interesting because of the cavity in the matrix, where bright red cinnabar crystals stand out. They are accompanied by lenticular baryte crystals. An old specimen from the Arguijo collection.

This sample has, for me, both a collection and scientific interest. It is a sample of cinnabar "veins" in its host rock, which has been perfectly polished to be able to see the structures of this breccia. Intense red colors of cinnabar snaking between fragments of quartzite impregnated with cinnabar, isolated crystals of pyrite and veins of dolomite. A true curiosity from Almaden to study under the magnifying glass.

Radial aggregates of stibnite crystals, very brilliant and in the rocky matrix. We can see some flattened crystals. Of this old mine where today it is difficult to find pieces.

This specimenbelongs from an Italian collection. It stands out for a colorful cinnabar crystal, with a good size (12 mm), transparent to translucent. Faceted, bright, intense red color. It is accompanied by several groups of crystals of the same species. A classic smaple with a pedigree, very difficult to see today. From one of the most Spanish classic localities.
