MD-199983 - Percylite - - Archived Caracoles, Sierra Gorda District, Tocopilla Province, Antofagasta Region, Chile small cabinet, 6.4 x 5.1 x 3.4 cm.
6.4 x 5.1 x 3.4 cm. A beautiful specimen of this rare mineral combination: apparently a strange admixture of Boleite & Pseudoboleite that is probably soon to be disallowed as a species name. Still, highly unusual, and with a color all its own. Ex. Philadelphia Academy of Sciences Collection.
MD-199984 - Percylite - - Archived Caracoles, Sierra Gorda District, Tocopilla Province, Antofagasta Region, Chile small cabinet, 7.6 x 4.7 x 3.1 cm.
7.6 x 4.7 x 3.1 cm. A beautiful specimen of this rare mineral combination: apparently a strange admixture of Boleite & Pseudoboleite that is probably soon to be disallowed as a species name. Still, highly unusual, and with a color all its own. Ex. Philadelphia Academy of Sciences Collection.
MD-207336 - Pseudoboleite - - Archived Amelia Mine, Santa RosalÃa (El Boleo), Boleo District, Mun. de Mulegé, Baja California Sur, Mexico small cabinet, 5.3 x 4.6 x 3.3 cm.
5.3 x 4.6 x 3.3 cm. Pseudoboleite is much rarer than boleite from the Amelia Mine at Boleo, Mexico. This fine piece features two, lustrous, indigo-blue pseudoboleite cubes to 7 mm aesthetically set on stabilized clay matrix. Actually, the pseudoboleite is the 3-dimensional outgrowth upon boleite, a cube of which remains underneath the pseudoboleite accretion. Ex. Bill Larson Collection. Bill and Ed Swoboda spearheaded a mid 1970s mining project at the Amelia Mine.
MD-215222 - Cumengeite, Pseudoboleite, Boleite - - Archived Amelia Mine, Santa RosalÃa (El Boleo), Boleo District, Mun. de Mulegé, Baja California Sur, Mexico thumbnail, 0.8 x 0.8 x 0.7 cm.
0.8 x 0.8 x 0.7 cm. This is an exemplary example of the epitaxial, or oriented serial growth, of these rare species one upon the other, with sharp form and good color as well. The Cumengeite is the sharp, pyramidal-like outgrowth popping out of one face of the central cube. All of the steppes upon the original simple cube of Boleite are in fact the related species Pseudoboleite. Thick Pseudoboleite epitaxially overgrew the Boleite cube, showing quite clearly even to the naked eye. Interestingly, only boleite is a silver species - the other two have no silver content. The crystals of all 3 species from this, the type locality, remain the best known by an order of magnitude, still today 100 and more years later. Ex. Dick Jones Collection.
MD-215226 - Pseudoboleite, Boleite - - Archived Amelia Mine, Santa RosalÃa (El Boleo), Boleo District, Mun. de Mulegé, Baja California Sur, Mexico thumbnail, 1.1 x 1.0 x 1.0 cm.
1.1 x 1.0 x 1.0 cm. This is an exemplary example of the epitaxial, or oriented serial growth, of these rare species one upon the other, with sharp form and good color as well. All of the steppes upon the original simple cube of Boleite are in fact the related species Pseudoboleite. Thick Pseudoboleite epitaxially here completely overgrew the Boleite cube, showing quite clearly even to the naked eye. Interestingly, only boleite is a silver species - the other two related species found here have no silver content. The crystals from this, the type locality, remain the best known by an order of magnitude, still today 100 and more years later. Ex. Dick Jones Collection.
MD-25825 - Pseudoboleite, Boleite - - Archived Santa RosalÃa (El Boleo), Boleo District, Mun. de Mulegé, Baja California Sur, Mexico thumbnail, 0.7 x 0.7 x 0.7 cm
A large, pristine and lustrous 7 mm dark blue cube of pseudoboleite coating boleite from Santa Rosalia, Boleo, Mexico. The 1 mm thick pseudoboleite epitaxially overgrew the 6 mm boleite cube. The crystal edges have the typical reverse step found in this rare mineral combination. Old dealer stock of Dr. Gary Hansen and not shown since the early 1980s! 0.7 x 0.7 x 0.7 cm
PAS-110 - Percylite - $ 300 SOLD Caracoles, Sierra Gorda District, Tocopilla Province, Antofagasta Region, Chile small cabinet, 6.4 x 5.1 x 3.4 cm ex. Philadelphia Academy of Natural Sciences
A beautiful specimen of this rare mineral combination: apparently a strange admixture of Boleite & Pseudoboleite that is probably soon to be disallowed as a species name. Still, highly unusual, and with a color all its own.
PAS-114 - Percylite and Schwartzembergite, and Atacamite - $ 300 SOLD Caracoles, Sierra Gorda District, Tocopilla Province, Antofagasta Region, Chile small cabinet, 7.6 x 4.7 x 3.1 cm ex. Philadelphia Academy of Natural Sciences
A beautiful specimen of this rare mineral combination: apparently a strange admixture of Boleite & Pseudoboleite that is probably soon to be disallowed as a species name. Still, highly unusual, and with a color all its own. To be frank, I haven't confirmed the presence of Schwartzembergite which is supposed to be a minute red stain...but I am pricing this, thus, as simply an attractive percylite and if you can find the Schwartzembergite, that is a bonus.
