OKH-611 (accidentally shot upside down)

OKH-611    Fluorite and Calcite    Huanzala, Peru.  Paul and Dawne Dunning Collection.  A wonderful specimen from days gone by.  This floater measures 6.5 x 3.9 x 3.6 cm.  The bulk of it is dark colored, metallic luster, sphalerites.  Some of these crystals are twins.  On the back matrix is covered by pyrite.  The showstopper is a beautiful pink, slightly purple, fluorite that measures 1.2 cm.  There are other fluorites on the backside but they are not very noticeable.  The nice one is totally gem and complex in form with cube and octahedron.  There are a few tiny bits of sphalerite on it’s surface.  There is zero damage to this fine display piece.  A very desirable example of the late 20th century material.  $320







OKH-640    Fluorite with Pyrite     Huanzala, Huanuco Dept., Peru.  Ex.  Paul and Dawne Dunning Collection.  This is a complete floater octahedral form and numerous attached pyrites.  Crystal shows a complex morphology, light green color, and translucence to gemmyness throughout.  The form is what many refer to as the classic "Aztec Pyramid".  It measures 3.5 cm on edge with the longest dimensions equaling 4.5 x 4.5 x 4 cm.  This is a magnificent specimen for the location.  The photographs do not do it justice.  And aesthetic and desirable miniature.  $450







OKH-650    Pyrite    Huaron, Peru.  Ex.  Paul and Dawne Dunning Collection.   This is a very nice large plate of crystals measuring 10 x 8.2 x 5.1 cm.  Individual crystals exceed 3 cm each and are a combination of cube and octahedral forms.  Both forms are about equal in development which is rather unusual.  The tag mentions stannite but I believe the secondary growths are also pyrite.  In either case is specimen is very clean and attractive.  A showy and unusual specimen from this prolific locality.  $175







OKH-620    Fluorite    Huanzala, Peru.  Ex.  Paul and Dawne Dunning Collection.   Is rather large specimen measures 11 x 7 x 4.8 cm it has most of its crystallization on one side.  The fluorites are up to 1.5 cm on edge each, they are transparent, light purple in color.  There is damage to the specimen however several crystals are fairly clean.  $30







OKI-641     Bornonite     Quiruvilea Mine, Peru.  An exceptional crystal of this uncommon material.  The specimen is dominated by one large crystal standing up on several smaller ones.  It appears to be a floater but is mounted in a perky box so it is impossible to tell without removal.  The luster is as good as it gets for this species and the crystal is hoppered.  The piece measures approx. 1.8 x 1.5 x .7 cm.   Zero damage and a superior TN specimen for this locality.  180$







OKF-619    Chalcopyrite, Pyrite, Sphalerite and Quartz    Casapalca, Peru.  Ex. Jay Walter collection.  A very fine chalcopyrite crystal sits centrally among the other minerals.  The chalco is 2.4 cm across.  The specimen measures 5 x 5 x 4.1 cm.  Good luster and form to all the minerals.  60$







Biggest calcite

Classic tetrahedrite

Sharp tetrahedrites with surface growth features

Typical pyrites

OKF-572    Hubnerite, Chalcopyrite, Quartz, Calcite and Tetrahedrite    Casapalca, Peru.  A fine, high luster display piece with a diversity of species.  The calcites are the largest at over 4 cm and they sit way up on the matrix of sulfides.  No damage and everything is obvious and clean.  The piece sits well for viewing and limits its matrix contacts to the base and back.  Not uncommon material but difficult to find in smaller specimens that are free of damage and have this diversity of mineral species.  A very reasonable price….85$







Hubnerite close up

Hubnerite on left lower edge.

OKI-178     Fluorite, Quartz and Hubnerite    Peru.  Several lustrus milky quartz crystals flank this partial octahedron of light green fluorite.  The entire specimen measures 5.8 x 5.5 x 4.5 cm.  The quartz have several small deep red hubnerite crystals embedded in their sides and bases.  The fluorite is of the “Aztec pyramid style with cubes modifying the surfaces of the octahedrons leading to a stepped appearance.  The octahedrons corners are modified as well (hexoctahedral?).  There is no damage.  One quartz looks dinged but it is a multiple termination and everything is clean.  Sets several ways for display and is better that the photos make it out to be.  A fantastic price on this one…..95$







OKF-472    Gratonite    Excelsior Mine, Cerro de Pasco, Peru.    Ex. Dr. Steve Chamberlain collection, prev. Ward’s Minerals, from the Oren Root collection.  This is most certainly a specimen found in the 1800s though an exact date is not provided with this wonderful provenance. The specimen is a 2 cm ball of crystals with on tiny area of matrix contact and a tiny area of missing crystallization (damage?).  It displays well from most all angles.  A rare piece unavailable in today’s market.  300$







Close up

OKF-665    Rhodochrosite    Sta Rita Mine, Peru.  Attractive pink 7.8 x 4.5 x 3.5 cm plate of crystals.  They are large, up to 2 cm each, and have a stepped growth effect.  No damage.  Luster varies due to an overgrowth of an unknown mineral which is white/ tan in color.  100$







OKF-626    Pyrite    La Libertad Mine, Quiruvilca, Peru.    Ex. Jim Turek Collection.   A good lustrous grouping of the less common octahedrons form this grouping.  The matrix is massive pyrite.  Great frontal view but only miner crystallization on back, one side and bottom.  8.5 x 7 x 5 cm overall.  Crystals to 1.4 cm on edge.  A nice, damage free, showy specimen which sits well and demands a second look.  60$






OKF-164   Manganocalcite on Quartz    Pachapaqui, Peru.  Ex.  Nancy Collins collection.  A small cabinet specimen seen in the photo measures 6.5 x 5 x 4.3 cm light pink manganocalcites formed domes on top of lustrous quartz.  A fine display piece of good luster and form.  Zero damage.  $85






Pyrite closeup

OKF-040    Fluorite and Pyrite     Huanzala, Peru.  This specimen is one of the nicest fluorites I’ve seen from Peru.  It is a big floater piece comprised of a single fluorite octahedron with highly modified, etched and hoppered surfaces.  It measures 5 cm on edge and is a light sea foam green color.  The fluorite id fluorescent and exceptional for the locality.  One small patch of purple.  The Pyrites are in clusters in pits in the fluorite and are modified by dodecahedral forms.  6.6 x 6.2 x 6 cm.  An outstanding and unusual fluorite specimen.  450$







OKD-519     Pyrite    Huanzala, Peru.  Ex. Dr. Steve Chamberlain Collection.  Good octahedrons of pyrite with minor cubic modifications form this low luster grouping.  5.2 x 5.2 x 2.8 cm thick.  More peripheral damage that I’d like to see.  25$







OKD-509     Pyrite    Huanzala, Peru.  Ex. Dr. Steve Chamberlain Collection.  Several big, high luster octahedrons of pyrite which are intergrown and sit up high on the all pyrite matrix.  What makes this piece special is quite obvious…the modifications to these octahedrons are very unusual.  I thought I was fairly decent at knowing my crystallography but this one has me baffled.  No damage to the main crystals but there is peripheral contact from other crystals.  6.5 x 6 x 3 cm with crystals to a cm.  Interesting surface features on a few faces.  Very unusual and interesting.  265$

OKD-505    Rhodochrosite on Sphalerite    Mamuelita Mine, Morochcha District, Yauli Prov., Junin Dept., Peru.  Ex Nancy Collins Collection.  This specimen is a large (13 x 7 cm ) plate of small rhodo crystals which create a druze on massive sphalerite.  No damage but there is some broken material along lower edge as a result of the material’s extraction.  This is clearly visible in the photo and could easily be trimmed off.  A good piece at an easy to handle price.   90$








OKD-395    Barite    Miraflores Quarry, Liata, Hualianca District, Hunaco Dept., Peru.  A beautiful cluster of gemmy golden yellow tabular barites to 4 cm on edge.  These barite sit up high on a well trimmed section of matrix which is coated by tiny dolomites and an unknown metallic mineral.  One barite on back of the specimen is cleaved.  This is a highly aesthetic piece with quite large crystals for the location.  225$







OKD-055    Pyrite, Quartz, Sphalerite   Peru.  An attractive show of cubic crystals and quartz.  One large crystal of sphalerite and some secondary pyrite overgrowths on one side of cluster.  Pyrites have nice striations and some hillock growths.  5.5 x 4 x 3.5 cm overall.  Very showy specimen for the low price of 40$ 







OKD-069  Enargite, Pyrite, Tetrahedrite  Quiruvilica, Peru.  7.5 x 5 x 4.5 cm dome of crystals dominated by well formed, silver colored enargite crystals.  Some lustrous pyrites in pyritohedral form.  Tetrahedrites are only partials and are minor.  125$







OKD-053    Tetrahedrite, Sphalerite, Galena, Quartz    Casapalca, Peru.  Ex. Dr. Steve Chamberlain Collection.   Here is a large plate of outstanding crystals of exceptional size for the location.  The piece measures 12 x 11 cm and is up to 5 cm thick.  The sides are mineralized on much of the piece and there is no damage.  The sphalerites are largest reaching over 4 cm each.  They are nicely translucent, yellowish and complex in form.  The tetrahedrites are exceptional in luster and reach 2 cm each.  Their form is clean and attractive.  The galena are also very complex and not as lustrous as the other minerals.  All crystals are evenly dispersed on the matrix.  A real winner.  580$







OKA-698 Barite/ Galena/ Pyrite Huanzala, Peru. Great damage free combination pieces with very high aesthetic value. White/clear barites to 2 cm with mostly bright and some dull galenas (sometimes hopper crystals). Pyrites are high luster but usually on the backside of the piece.
