THE FOLCH COLLECTION

The Folch Collection

The Folch Collection was known during the period 1960-1980 as one of the best private collections in the world. It was famous worldwide for its size (more than 15,000 specimens), the quality of the pieces, the large number of classic specimens, which are now almost impossible to obtain, and the style of the collection, which is surprisingly 'modern'. Sr. Folch (Joaquín Folch i Girona) collected during a period when the style of most collectors in Europe consisted of gathering large specimens of rare minerals, and in which esthetics and perfection were not that important. That said he actually tended to collect smaller specimens that were esthetic, and, where possible, damage free. On the death of Sr. Folch, in 1984, the collection passed to his son Alberto, and when he in turn died to his grandson Joaquín Folch who wisely decided to keep the collection exactly as his grandfather had it (including the display cases). So the collection was kept together and its enormous historical value has not been lost.

While I was a teenager, and still rather young, I had the luck to have been warmly invited by Sr. Folch to visit the collection. I made numerous visits, and with him beside me I obtained an enormous amount of mineralogical information, which went far beyond what I would have learned anywhere else. Given this experience I have always had a strong connection with the collection.

During my ongoing contacts with the Folch family a moment arrived when they suggested the idea of updating the collection so as to make it more up to date - since 1984 nothing new has been added and a significant gap in the minerals found since then has developed. After lots of friendly, unhurried discussions the Folch family asked me to help them with this updating process. To do this we have the luck that the collection includes many attractive duplicates. These duplicates do not add much to the Folch collection, as there are other examples of all of them, but given their unusual localities or simple high quality they are still good commercial specimens.

So, for the first time, the duplicate specimens from the Folch Collection will emerge into the sunlight. Each one of them has hand written notes made by Sr. Folch himself as well as, in many cases, his official label and number (in the case that they were part of the official collection). The duplicates will be sold during the shows that we normally attend, and also through our web site and store in Barcelona (you need to arrange a visit beforehand, which we will try to find a way of accommodating).

This project will take us a long time, as the pieces available are numerous and neither the family nor I wish to make the choices too quickly. The idea is to work slowly and select the pieces in a very systematic and careful manner. We think that given the special characteristics of the specimens that will be available and their historical value this will be a great chance for many collectors to obtain pieces that would otherwise have remained pure dreams.

We hope that little by little we can satisfy all those that wish to acquire a duplicate from the Folch collection and we can assure them that this task will give us far more pleasure than simple economic benefits. Sr. Folch was my spiritual father in mineralogical terms so handling his minerals and helping to improve his collection with new purchases is a fantastic sensation for me.

I cannot thank the Folch family enough for their good faith and for their wish to improve the collection. They are helped by the undeniable support and enthusiasm of Francisco Riquelme, the current conservator of the collection, and between them they have taken a step that many people have wished them to take and that will give collectors worldwide great joy, as well as increasing interest in and knowledge of the Folch collection within Spain and the rest of the world.

RA60V0: Groups of small octahedral crystals of Cuprite with sharp faces and edges and with intense red color. They are on a matrix of massive Cuprite and with thick growths of Copper.
With a label of the legendary company Foote that we'll send to the buyer.
Copper Queen Mine, Bisbee, Warren, Cochise County, Arizona  USA (±1952)

Specimen size: 6.1 × 3.6 × 3.1 cm = 2.4” × 1.4” × 1.2”

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

RH6V0: Arborescent growths of crystals of native Copper on matrix, with mossy aggregates of very thin fibrous crystals of Cuprite (variety chalcotrichite), very bright and with deep red color.
We’ll send the Minerals Unlimited label to the buyer of the specimen.
Ray Mine, Ray district, Pinal County, Arizona  USA (±1963)

Specimen size: 6.8 × 5.5 × 2 cm = 2.7” × 2.2” × 0.8”

RD96V0: Arborescent growths of copper covered by cubic crystals of Cuprite, translucent, bright and vivid red in color. Of excellent quality for the locality, a great North American classic.
Ray Mine, Ray district, Pinal County, Arizona  USA (±1964)

Specimen size: 9.3 × 6 × 1.5 cm = 3.7” × 2.4” × 0.6”

Main crystal size: 0.2 × 0.2 cm = 0.1” × 0.1”

Quartz Amethsyt with Quartz and Epidote

RC86V0: Group on matrix of transparent crystals with good size, color and luster. With color zoning, more concentrated on the terminations. Surely one of the first known samples from Las Vigas, as the old label of Lidstrom’s indicates. It reflects the uncertainty of the locality at the time because the original label says “Guerrero” , with a later correction of Folch, that locates the sample properly in Veracruz. We’ll send the Lidstrom's label to the buyer of the specimen.
Las Vigas, Veracruz  Mexico (±1969)

Specimen size: 7.6 × 6.8 × 3.7 cm = 3.0” × 2.7” × 1.5”

Main crystal size: 4 × 1.7 cm = 1.6” × 0.7”

Bustarviejo, Madrid  Spain

Specimen size: 7.1 × 7 × 5.2 cm = 2.8” × 2.8” × 2.0”

Minas da Panasqueira, Beira Baixa  Portugal (±1972)

Specimen size: 9.2 × 5.7 × 3.2 cm = 3.6” × 2.2” × 1.3”

MC96V0: From the type locality for the species. Groups of very acute dipyramidal crystals with sharp faces and edges. They are transparent, with a slightly green color and one of them with a nice and neat butterfly twin. They are on a matrix of Quartz with blue Vivianite. A German classic.
Hagendorf, Waidhaus, Oberpfδlzer Wald, Bavaria  Germany (±1959)

Specimen size: 7.6 × 7.5 × 6.7 cm = 3.0” × 3.0” × 2.6”

RR64V0: An excellent sample from one of the most classic localities for the species but rarely appeared there in significant sharp crystals. The small crystals of this piece are morphologically complex, with the dominant faces of the rhombohedron. A lot of them are individual and transparent, very bright and on matrix. An European classic.
Idria Mine, Idria  Slovenia

Specimen size: 8.4 × 6.8 × 4.4 cm = 3.3” × 2.7” × 1.7”

Main crystal size: 0.1 × 0.1 cm = 0.0” × 0.0”

RG14V0: Groups of primary Malachite crystals. They have simple and very well defined forms and are very bright. The groups are in matrix with small crystals of Quartz. It is from an old find, never repeated later, in spite of the fact that the locality has been repeatedly revisited in recent years.
Irhoud Mine, Safi, Doukkala-Abda  Morocco (±1979)

Specimen size: 8.2 × 7.8 × 5.2 cm = 3.2” × 3.1” × 2.0”

Order
Smithsonite with Cuprite

RP96V0: Group of Smithsonite crystals formed by a dominant flattened rhombohedron and poorly developed prismatic faces. The crystals are bright, translucent to transparent, they have a very intense yellow color and they are on matrix with Calcite and small crystals of Cuprite variety Chalcotrichite.

Specimen size: 5.2 × 4.7 × 3.6 cm = 2.0” × 1.9” × 1.4”
