SOUTH AMERICA

ARGENTINA
Neuquén, La Cecilia mine
Stalactites of barite (or celestine– some need testing) with smaller crystals, this one 4.5 cm. One source labeled as pseudos after calcite but no apparent reason for this.
 
  BOLIVIA
Potosí, Machacamarca, Colavi mine  
Clear glossy tabular crystals to 2.5 cm on siderite. Mindat.org.
 
Potosí, Llallagua
White thin blades, somewhat translucent, perhaps to 1 cm. MR 37/2.
   
  BRAZIL
Acre
  Cutting material, chunks to 10 cm. Obtained by Brazilian dealer Dilermando Melo Filho (Dilo), at Tucson 2010, not further locality info available. Saw 714.67 cut stone, probably from this locality, at Hans-Jurgen Henn booth at Tucson 2014. Grey.
   
Paraiba, near Joäo Pessoa, quarry near Cidade Baixa prison
  Clear/gray thin tabular blades to 4.5 cm.
 
Rio Grande do Sul
White sawtooth thin doubly terminated tabular crystals to 6.5 cm with small calcite rhombs on typical "geode" matrix, amethystine chalcedony layer.
   
  COLOMBIA
Boyacà, Pauna, La Marina mine
 
Small (1.5 cm) translucent light yellow blades on matrix with 2 nd generation small clear/white blades. With dolomite, pyrite. Also thicker golden blades to 2.7 cm, on limestone/pyrite in large specimens but with black/pyrite coating, much of which cannot be removed.
   
Boyacá, Mun. de Muzo
  Thin golden blades, glossy, tabular with "pyramidal" modifications to 2.5 cm each in group, 5.7 cm. Very slight damage/contacts on side edges. New at Tucson 2012.
   
  PERU
Huancavelica
  Thin blades to 4 cm coated with tiny pyrite crystals. Mine/district not given.
   
Huancavelica, Castrovirreyna district, San Genaro mine
  Large white crystals with quartz are classics. These butterfly crystal groups are 4 cm, 8 cm specimen; some groups reportedly reached 10 cm.
   
Huancavelica, Huachocolpa
  Grey thin typical tabular blades to 2 cm in group with nearly black coating, seemingly unaffected by most acids and cleaners. Some flakes off. With tiny as-yet unknown sulfides, looks like tetrahedrite. (Rare veenite cited from locality). New material 2008.
   
Huancavelica, Julcani district
  Clear, doubly terminated nearly chisel-shaped crystals, flattened, to 3+ cm on small greenish balls of siderite, 10 cm. Thin milky tabular blades, stacked, to 3 cm, rimmed with tennantite and marcasite and small sulfides on bottom. Probably some pyrite also. 4x3x2.5 cm.
   
Huanuco, Huamalias, Miraflores mine
  Many habits occur here; first appeared in quantity at St. Marie-aux-mines in 2005. Usually labeled Cerro Warihuayin for the hill of the locality. Left to right:
  • Very clear thin rectangular blades to 3-4 cm on dolomite;
  • Thicker golden blades, also transparent, with "sawtooth" edges to about 3 cm in group;
  • Thick, dark, zoned crystal, 4 cm;
  • Like many, this group (3.5 cm) appears somewhat light blue if it picks up the color from its surroundings and light source; grey to clear in other lighting;
  • Thin hexagon-shaped complex 4 cm crystal on matrix;
  • Gemmy gold complex crystals to 3 cm;
  • 6 cm large thin blade, slight green tinge, with dolomite, on matrix;
  • Very clear crystals to 3.5 cm, 0.6 cm thick, 6 cm specimen;
  • Well-zoned transparent crystals to 1.8 cm, 4x5 cm overall;
  • Thick tabular dark yellow crystals to 3 cm, transparent with some zoning and pyrite inclusions, complex terminations. 5.5x5.5 cm overall.
  • Pale yellow transparent very thin complex tabular blades to 3.3 cm in butterfly arrangement, no damage, 4x4x4 cm.
Ancash, Huanzala mine
  Nice milky/clear tabular crystals to 1 cm in groups on bright galena crystals to nearly 1 cm, small pyrite crystals, 8 cm. White zoned blades to 1.5 cm on brilliant pyrite octahedrons (labeled Huaron; such octahedrons not as common from Huaron as other forms).
   
Junín, Morococha district
  Thin white banded barite blades to 2 cm, some sparkly quartz druse on them, w/clear, amber sphalerite, rough xls to 1 cm, all on drusy quartz.. 7x5 cm. Jaroslav Hyrsl provided locality info.
   
La Libertad, Quiruvilca district
  Clear-tan tabular blades to 3.5 cm perched on pyrite; clear tabular double crystals to 3 cm on orpiment crystals Slightly milky to clear, lustrous thick tabular crystals to 3.4 cm on edge, perched on orpiment botryoidal matrix (much realgar still left underneath in the matrix). Some bright yellow orpiment "dots" on the barite as well as orange balls. Several realgar needles to 0.4 cm on one crystal (as of 2010, anyway). 9x10 cm, quite showy. Very white nearly opaque thin tabular crystals to about 1.5 cm each in group, very thin plate, with very small orpiment crystals and small "dots" of orpiment. 7x5x1 cm. Thin translucent milky bladed crystal group, one very large, serrated edges which have thin coating of deep purple. Lustrous, on matrix of small barites and quartz. 7x6.5x5 cm. No damage. Large crystal ~6 cm.
   
Lima, Casapalca district
  Very thin beige blades to 3 cm on pyrite crystals, 4 cm. Also clear, zoned tabular blades to 2.5 cm on (probably) polybasite. This one appeared in '98, when Bella Vista mine barite was selling, but not so labeled.
   
Lima, Raura district  
  White blades to several cm with sulfides. See MR 28/4.
   
Pasco, Huaron district
  Pointed, glassy tabular crystals to 1.5 cm, various zones of light blue-gray, nearly transparent, 12 cm. Often with pyrite.
