Very large group of rhodochrosite crystals, very bright, transparent and richly faceted. They show interpenetrated figures of the rhombohedron and the escalenohedron. The pink color is very uniform and intense. They are disposed forming aggregates or as isolated individuals, on a matrix with kutnohorite. A old piece belonging of the first specimens those arrived from these Peruvian mines.

These specimens show a matrix formed by arsenates such as erythrite and associated sulphides and arsenates of cobalt and iron. We can observe on both the presence of arborescent, filiform and laminar gold aggregates. SEM analysis has shown that this is a variety of gold rich in silver (23-24%w): electrum.
Under loupe, we can enjoy that some of these gold aggregates are formed by small crystals of octahedral to cubic forms. We can theorize a secondary genesis for this gold-electrum. We have analyzed the matrix of these specimens observing that the bright metallic matrix corresponds to a mixture of cobalt arsenides, probably skutterudite, and other sulphides. We will send all analyzes to the buyer. The deposit where the electrum appeared has been totally covered by mine lands, so more samples can not be obtained on the field. A very rich gold-electrum specimen.

These gold nuggets were collected from the alluvial deposits of the quaternary paleoterraces of the Tormes river, pass through the locality of Salvatierra de Tormes. The analysis carried out have shown the presence of silver. Some specimens contain fragments of quartz. Thin, good size and brilliant. Weight: 0.20 g.

Rich group of very sharp metatorbernite crystals, with an intense green grass color, showing the combination of the first and the second order dipyramids, truncated by pinacoidal faces. Its intense color gives a nice contrast with the white quartz matrix. Large open cast mines ans small prospects of kaolinite with some quartz veins in which torbernite crystals have been found. We could say that this locality is included in the most worldwide important torbernite localities due to the crystal quality, size and multiple habits.

Really nice botryoidal aggregates of malachite, with intense color and a velvety surface due to the small crystals forming globular aggregates. Very different specimen from this mine, well known for the type locality of cornetite species. All aesthetics.

A rich group of scalenohedral calcite crystals, very acute, translucent, of good size and from this classic Andalusian locality. Not very common in these mines. Under the ultraviolet (LW) light they present a very remarkable red-pink fluorescence.

Sold

This old specimen stands out for the large number of oligoclase crystals, a variety of albite, very well defined and rich in facets. They are accompanied by prismatic crystals of actinolite, with an intense green color. A piece for collectors of Iberian deposits. These quarries were worked until the end of the 60s and the beginning of the 70s of the last century.

This octahedral green fluorite is perched on a druse of quartz, with window forms. It shows defined faces and edges. Color is intense with transparence. On a matrix of feldspar. This is from a small tungsten mine that was worked intermittently in the past including by the Russian government as a source for tungsten back in the 1980s. Few good minerals came out, and fewer still in this size and quality.Fluorescent under LW-UV.

Sold

Groups of fan-shaped epidote crystals, very bright and with transparency and disposed very aerial on the ophite matrix. Intense green color, brightness and transparence. It is currently prohibited to collect in this area. A sample with a good size (12 cm.) and excellent quality, from the classic town of Casterner.

These fluorite specimens are particularly interesting as they show dodecahedral crytals, which is an uncommon habit for fluorite, with minor octahedral and cube faces. To give a touch of aesthetics, crystals have a marked geometric color zoning, revealing a purple replica of the larger crystal inside. Good transparence and brilliances. They are disposed on a quartz matrix. Really aesthetic.

Very brilliant specimen of goethite, from this classic Moroccan mine. It presents an aesthetic botryoidal aggregate, with an intense metallic luster and a deep black color.

An aesthetic royal-blue cavansite group of sharp crystals, perched atop stilbite-covered basalt matrix on this fine and showy piece from the Wagholi Quarry of India.

An excellent specimen formed by numerous epidote crystals, from the classic locality of Casterner. Fan-shaped crystals, they are very bright and with an excellent transparence. Better in "person" than in the pictures. Samples of this quality are already few. It is currently forbiden to collect in the area.

Group of huge size orthoclase crystals, showing the complex faces. Nice slightly orange color and defined edges and faces. It was collected many years ago near of the Montseny massif; this area was well known for orthoclase mineral collectors. A classic from a classic Catalan collection.

These specimens of banded flint were collected decades ago in the area of El Brull, in the Montseny massif, and identified as agate. They appear in nodules and veins, embedded in a siliceous limestone, presenting bands of gray tones, between light to dark gray. These kind of striped flind are well know in jewelery, and very appreciated. It is a unique curiosity of the Catalan mineralogy of many years ago.

Rich group of pyrite crystals, isolated and disposed in the original marl matrix. Exceptional luster and some of them show flattened prismatic shapes. From a classic mine for the Spanish mineralogy. Good size specimen.

It is not very common to find specimens of lorenzenite, a rare sodium silicate titanate, of these Russian pegmatites. The piece shows some crystals with defined faces and edges, intense black and brilliance, some doubly ternminated. Very interesting specimen collected in this large agpaitic pegmatite body discovered in 1996 on the northern flank of the Umbozero mine on Alluaiv Mt. Intensely hydrothermally reworked, extremely Na-rich, CO2-rich and relatively Si-rich pegmatite. We will send analysis to the buyer.
