Minas Gerais  Brazil (±1964)

Specimen size: 4.4 × 2.2 × 1.6 cm = 1.73” × 0.87” × 0.63”

RB47H7: The specimen is extraordinary. Crystals have very sharp faces and edges, they are bright and transparent and form an elegant crown contrasting with the smoky quartz crystal matrix. On the back, the sample is partially covered by Muscovite. We call attention especially to the extraordinary deep pink color, deeper than usual, and also the definition of most of the crystals.
Alto da Pitorra, Laranjeiras, Galiléia, Vale do Rio Doce, Minas Gerais  Brazil (±1967)

Specimen size: 8.7 × 7 × 4.4 cm = 3.43” × 2.76” × 1.73”

Governador Valadares, Minas Gerais  Brazil (±1964)

Specimen size: 3.1 × 1.5 × 1.4 cm = 1.22” × 0.59” × 0.55”

RQ26L3: If we pay attention on the label date (1980) we could consider that this specimen must be part of the first “Watermelon” found in Santa Rosa. The crystal shows a marked color zoning and an excellent transparency and brilliance.
Santa Rosa Mine, Itambacuri, Minas Gerais  Brazil (±1980)

Specimen size: 3.6 × 0.7 × 0.7 cm = 1.42” × 0.28” × 0.28”

RN96H7: Prismatic crystal with an excellent termination. The color zonation is very well marked with the inner core between red and mauve and the bluish green exterior. It is curious to find this piece in the Folch collection because he purchased it before 1980, so it could be one of the first “watermelons” found at the locality.
Santa Rosa Mine, Itambacuri, Minas Gerais  Brazil (±1980)

Specimen size: 3.6 × 1 × 0.9 cm = 1.42” × 0.39” × 0.35”

Minas Gerais  Brazil (±1961)

Specimen size: 13.2 × 5.6 × 2 cm = 5.20” × 2.20” × 0.79”

Poopó, Oruro  Bolivia

Specimen size: 3.8 × 3.5 × 2 cm = 1.50” × 1.38” × 0.79”

RA96G2: A floating specimen with platy crystals in an arborescent growth. The locality is very well-known but specimens, especially of high quality like this, are actually very scarce.
Corocoro, Provincia Pacajes, Departamento La Paz  Bolivia (±1980)

Specimen size: 14.8 × 4 × 1.5 cm = 5.83” × 1.57” × 0.59”

Main crystal size: 0.3 × 0.2 cm = 0.12” × 0.08”

RL63J1: Very aerial group of complex crystals, very rich with faces and considerably bright. Although on the label the only locality is Chile, we can presume, by its characteristics, it is from Copiapó area.
The specimen is with a label from the now defunct company Suministros Escolares de Barcelona (SEC). We will send the label to the buyer.
Copiapó, Atacama  Chile

Specimen size: 2.7 × 1.3 × 0.8 cm = 1.06” × 0.51” × 0.31”

Main crystal size: 0.7 × 0.4 cm = 0.28” × 0.16”

Capillitas Mine, Andalgalá Department, Catamarca  Argentina

Specimen size: 11.5 × 8.8 × 1 cm = 4.53” × 3.46” × 0.39”

The sample is with a label and the collection card that we'll send to the buyer.
Capillitas Mine, Andalgalá Department, Catamarca  Argentina (±1960)

Specimen size: 12.3 × 8.7 × 2 cm = 4.84” × 3.43” × 0.79”

Specimen size: 5 × 4 × 3.2 cm = 1.97” × 1.57” × 1.26”

Main crystal size: 4 × 3.6 cm = 1.57” × 1.42”

RB46L3: Classic specimen of Scholzite that could come from the last 1960s find. Sprays of white acicular crystals in a closed vug, with some inclusions of clay and on a cavernous Dolomite matrix. Specimens of this rare hydrated calcium and zinc phosphate are scarce.
Reaphook Hill, Martins Well, Finders Rangers, South Australia  Australia (±1968)

Specimen size: 6.6 × 4.5 × 2.9 cm = 2.60” × 1.77” × 1.14”

Main crystal size: 1.6 × 0.1 cm = 0.63” × 0.04”

RP10M5: The crystal is formed by the very well defined forms of a prism and a dipyramid. It is translucent and has slightly pinkish shades in some zones. The sample is of an uncommon quality for the locality.
Mud Tank, Strangways Range, Alcoota Station, Central Desert Region, Northern Territory  Australia (±1968)

Specimen size: 2.4 × 2.1 × 1.8 cm = 0.94” × 0.83” × 0.71”

RB13S7: The sample is a classic for the species and has a high quality due to its color, the crystalline aspect of the Népouite and the silky luster. The original label indicates that it was acquired by Folch from Deyrolle (Paris) in 1933.
  New Caledonia (±1933)

Specimen size: 9 × 7 × 2.3 cm = 3.54” × 2.76” × 0.91”

RP59V0: Very sharp crystal with neat faces and edges, translucent, and with a very deep and uniform green color. Surely one of the first (near 1980) Afghan diopsides to arrive in Europe.
Nuristan Province  Afghanistan (±1980)

Specimen size: 2.4 × 1.5 × 0.9 cm = 0.94” × 0.59” × 0.35”

RR8P8: Probably this is one of the first Diopside crystals from Afghanistan to arrive in Europe, due to the fact that it was obtained at the locality by Alberto Folch in 1980, as the original label says. The single crystal has very well defined faces and edges, a very deep and uniform green color and it is rather transparent.
Nuristan Province  Afghanistan (±1980)

Specimen size: 2.9 × 0.7 × 0.6 cm = 1.14” × 0.28” × 0.24”

RQ59M0: Excellent miniature. This Diopside crystal has very sharp faces and edges, also an excellent deep color and brilliance.
The handwritten Folch label indicates that it was self-collected by Mr. Folch in 1980 and we can be sure that it was one of the first Diopside specimens from this locality to come to Europe.
Nuristan Province  Afghanistan (±1980)

Specimen size: 2.9 × 1.3 × 0.8 cm = 1.14” × 0.51” × 0.31”

TT36I8: Crystals sit on rock matrix and have a near tabular habit. Their terminations have very well marked triangular forms. Color is quite good and they have some degree of transparency, visible under a strong light.
Mysore, Chamraj  India (±1973)

Specimen size: 4.5 × 3 × 2.3 cm = 1.77” × 1.18” × 0.91”

Main crystal size: 1.8 × 1.4 cm = 0.71” × 0.55”

RM11M5: The sample is from a classic locality but, at the same time, uncommon. The crystals of Axinite-(Fe) are poorly defined but they offer the advantage of being associated with Quartz pseudomorphs after Danburite.
Obira Mine, Ono-gun, Oita, Kyushu Island  Japan

Specimen size: 4.4 × 3.3 × 1.9 cm = 1.73” × 1.30” × 0.75”

Main crystal size: 1 × 0.4 cm = 0.39” × 0.16”

RY87I2: The floating crystal has considerable size and it is very much defined as usual on samples of this size. On the front face is easy to see the hexagonal striations formed while the crystal grew. It is from a deposit actually that is now finished.
Shirakawamura, Gifu, Chubu, Honshu Island  Japan (±1961)

Specimen size: 6.3 × 4.6 × 3 cm = 2.48” × 1.81” × 1.18”

RV76H7: Beautiful miniature. It is a group of crystals having an extraordinary deep color. Faces and edges are so sharp that they seem polished. The locality itself is very original.
Eonyang, Kyeongsangnamdo  South Korea (±1974)

Specimen size: 3.5 × 2.6 × 1.6 cm = 1.38” × 1.02” × 0.63”

Main crystal size: 1.2 × 0.9 cm = 0.47” × 0.35”

RJ96H8: The locality is really interesting for its rarity, but we add that the sample is very esthetic, very well preserved and it has a deep smoky color, with darker inner inclusions.
Eonyang, Kyeongsangnamdo  South Korea (±1974)

Specimen size: 8 × 6 × 6.5 cm = 3.15” × 2.36” × 2.56”

Main crystal size: 6.5 × 1.5 cm = 2.56” × 0.59”

RM26AE6: Very sharp floater Scheelite crystal, complete, dipyramidal and with a clear honey color, very much clearer than usual for the Korean samples that usually are dark brown.
The sample is from the Joaquín Folch duplicates collection, whose label we’ll send to the buyer.
Tae Hwa Mine, Neungam-ri, Angseong-myeon, Chungju, Chungcheongbukdo  South Korea

Specimen size: 3 × 2.8 × 2.7 cm = 1.18” × 1.10” × 1.06”

RQ73H0: Actually the pieces of Scheelite from Korea are now really rare. On this one the perfect definition of faces an edges on the pyramidal crystal and also its luster is specially interesting. The Scheelite is, at the same time with a perfectly formed crystal of Quartz, partially covered by Dolomite. To all this we must add its very original lilac-purple color, visible under a very intense light, as the picture shows.
Tae Hwa Mine, Neungam-ri, Angseong-myeon, Chungju, Chungcheongbukdo  South Korea (±1974)

Specimen size: 5.5 × 3.7 × 3.4 cm = 2.17” × 1.46” × 1.34”

Main crystal size: 3.6 × 3.5 cm = 1.42” × 1.38”
