OKN-643    Sphalerite and Quartz     Lian Shan, Guangdong Province, China.  A large heavy pair of sphalerite crystals with a frontside coating of tiny bright quartz points.  10.6 x 7.5 x 5.5 cm overall.  One sphalerite is twinned and the other may or may not be but is interesting for the well developed growth hillocks seen in the last image.  There are a couple of bumps on top and back but front with the quartz is damage free.  The sphalerite is lustrous (resinous as it should be) and slightly translucent.  An impressive sphalerite specimen!  $195









OKK-565    Barite on Fluorite    Denton Shaft, Hardin County, Illinois.  Ex. Nancy Collins collection.  Honey yellow crystals to over 2 cm each on purple fluorite.  The barites are special while the fluorite is not.  They are lustrous and extremely well formed.  Only damage is one small missing barite (not even in the main grouping) so it displays great.  Circ. 1960s specimen so it could use some cleaning.  Excellent in-hand.  9.6 x 6.1 x 4 cm.  $250

OKK-559     Apophyllite, Stilbite, Stalactitic Chalcedony      Jalgaon, India.  Beautiful example of one of these with huge double terminated apophyllites to 7.5 cm each.  Front is damage free, back shows some cleaves and minor contact.  10 x 8.4 x 5.2 cm.  This example is more typical of nice quality material from decades ago.  We don't see it this nice as much any more.  Much better in-hand.  Will not disappoint.  $185









OKN-644     Sphalerite and Dolomite      Red Skin Mine, Oklahoma.  Ex. Dawne and Paul Dunning collection.  Attractive damage free plate measuring 10.4 x 7.1 x 3.3 cm.  Coated by well separated sphalerite crystals to 2.5 cm eash and smaller, red gemmy crystals.  Classic American material, damage free and crystallized on almost all surfaces.  $80









OKK-572      Weloganite      Upper Sill, Francon Quarry, Montreal, Quebec, Canada.  Ex. Dr. Steve Chamberlain collection.  A large opening filled by beautifully formed weloganites to 1.5 cm each.  Personally collected by Steve in 1978 from a now very famous, inaccessible site.  This is an exceptionally fine piece with no damage to the crystals, a much large void than is normally seen and good sized, nicely colored, well formed crystals.  The luster is normal for the species, which is rare, and the piece is sawn flat on it's base so it displays perfectly.  The piece of hair in the photos is distracting so I have removed it...sorry.  Tough to get this material in this fine an example.  $350










OKN-645     Creedite     Abasolo Mine, Navidad, Durango, Mexico.  I by these occasionally when they are in examples as good as this one because the site is no longer producing.  This piece is 8.5 x 8 x 8 cm an in excellent condition with only a couple of crystal being missing.  It views great from any direction, has a nice color mix and sits well.  Better than normal transparency to the crystals and great form to the grouping itself.  These are getting tougher to fine especially in good condition.  $180
