OKP-478

OKP-478      Fluorite     El Hamman Mine, El Hamman, Meknes, Fes- Menkes, Morocco.  Ex. Harold Dibble collection.  This disc of fluorite measures 6.7 x 6 x 2.3 cm overall.  The crystals are transparent and a pale green color.  It has one tiny spot I observe under magnification that is a small cleave so it is not totally spotless... it will appear so in-hand, however.  The pyrite balls are brighter than they appear as I have cleaned this specimen since it was photographed.  These are desirable specimens seldom seen in this quality and for this price.  $225

OKP-482     Pyromorphite      Los Burrachos, Sierra Horena, Spain.  Ex. Bob Borofsky.  This is a magnificent example of this uncommon material.  It has large crystals to almost a cm each on every side of the specimen.  It shows no points of contact but does have a few regions that are not crystal encrusted as can be seen.  It measures 9 x 7.4 x 4 cm overall.  I see only one crystal missing on the piece so it is in exceptional condition given the coverage.  That spot is facing you in the first image and is at the top along the edge of the piece so it is not distracting.  The luster  is good with the ones on the side I have labeled Back?? being slightly duller.  This one could be displayed nicely several different ways.  Great quality, size of crystals, coverage, and overall aesthetics on this one.  $400

OKP-479      Fluorite on Barite      Berbes, Auturias, Spain.  Ex. Bob Borofsky.  This specimen measures 10.5 x 8 x 4.1 cm and has nice fluorites to 1.4 cm on edge.  The fluorite sit on cream colored, partially goethite coated barite blades.  The fluorites are water clear but show light frosted surfaces with interesting little depressions that obscure internal views of the crystals.  The piece is crystallized on all sides and shows only a small area of contact on one edge.  There is no damage tot he barites or the many fluorites, large and small, that are scattered about on this piece.  This is an important European fluorite locality.  $275

OKP-479      Fluorite on Barite      Berbes, Auturias, Spain.  Ex. Bob Borofsky.  This high standing dome of crystals measures 8.8 x 7.4 x 6.5 cm and is all barite blades with scattered fluorites on their surfaces.  The base is flat so it sits nicely and can be observed from any side.  One side has some chipped barites, mostly near the base, but all the fluorites on every side are in excellent condition.  The fluorites are clear and have frosted surfaces.  They are highly modified in some cases and interesting.  There is a heavy tan deposit coating some regions, probably quartz.  $95

OKP-481      Fluorite with Barite      La Collada, Asturias, Spain.  Ex. Bob Borofsky.  This dark purple, translucent to transparent group of fluorites is as interesting as it is attractive.  The upper surfaces look clear while the interiors are a grape purple color, as seen.  They show dodecahedral modifications that give their edges a beveled appearance and some are hoppered.  The back is also nicely crystallized but relatively unattractive compared with the front.  The barite is attractive as well.  The piece measures 6 x 5.9 x 3.5 cm and sits on edge a couple of different ways showing off the specimen well.  Not damage, just the expected edge contacts.  Classic!   $175
