OKP-363     Fluorite      Stoneco, Auglaize, Junction Paulding Co., Ohio.  Ex. Harold L. Dibble collection.  These fluorite crystals are deep purple in color with exceptional surface iridescence.  The cubes surfaces are also covered by scalloped surface hillocks making them difficult to even recognize as cubes.  The specimen measures 10.3 x 6 x 4 cm.  One crystal on edge has breakage from contact so looks lighter in color (seen at bottom right of close-up photo).  $60

OKM-107     Adularia and Chlorite    Val Crystallina, Lukmanier, Graubunden, Switzerland.  Ex. Harold L. Dibble collection.  This crystal measures 7 x 4.6 x 4 cm and is nicely twinned.  The penetration twin shows nice, sharp overlapping flanges on front and back..  There is only minor chlorite but it adds a nice contrast to the piece.  There is minor edge chatter in a couple of spots, as seen, but it is obvious that the overall condition is very good.   Large crystal size, good translucent, and a nice luster make this a desirable specimen.  $190







OKM-212       Calcite    Irai, Rio Grande do Sul, Brazil.  Ex. Harold L. Dibble collection.  This is a small, star burst shaped cluster of crystals that came from within an amethyst cathedral.  It measures 5 x 4.1 x 3 cm.  It is a floater (no points of contact) and is damage free.  It is very uncommon to see these outside of a amethyst geode and as floaters they are almost non-existent.  $225







OKM-213    Quartz Faden     Minas Gerais, Brazil.  Ex. Harold L. Dibble collection.  The faden is obvious in this one.  It measures 8 x 5.5 x 2.7 cm.  There is some very minor edge chipping but it is in excellent condition, overall.  Light veils throughout specimen otherwise glass clear.  $75







OKM-996      Diopside    Orford Nickel Mine, Quebec, Canada.  Ex. Harold L. Dibble collection.  This is a fine example of these unusual, chisel shaped diopside crystals.  It measures 5.5 x 1.6 x 1 cm.  It is damage free, high in luster, attractive surface texture, and does not have distracting contacts like many of these crystals do have.  It has a healed break near its base that is not at all distracting.  $85







OKM-991    Barite     St. Saturnin, Puy de Dome, France.  Ex. Harold L. Dibble collection.  This single crystal is flawless internally.  It has contacts from other crystals as can be seen but the damage is very difficult to detect (a couple tiny rubs).  Nice surface features add interest.  Great luster and nice even amber color.  3.5 x 2.7 x .8 cm.  On an acrylic base, as seen.  Very nice specimen!  $80







OKM-215     Calcite      Guanajuato, Mexico.  Ex. Harold L. Dibble collection.  The poker chip crystals have always been a popular Mexican classic and they have become more difficult to find.  This grouping measures 11.4 x 6.5 x 4.5 cm.  It sits on edge for display and has only the slightest of rubs to a few crystals.  $60







OKM-216     Dolomite      Eugui, Navarra, Spain.  Ex. Harold L. Dibble collection.  There should be no argument that these are the finest dolomite crystals to be found anywhere in the world.  This group of twinned crystals measures 4.7 x 3.6 x 2.2 cm.  There is very minor damage to largest crystal, as seen, but it is not distracting, or for that matter noticeable (unless in high magnification like these images).  The piece displays nicely and is an outstanding miniature.  $175
