        Treasure Mountain Herk.                                                  Crystal Grove Herk.                                                              Crystal Grove Herks.                                   Herimer Mines and Resort Herk.

      

The majority of these specimens are from Treasure Mountain in Little Falls, NY.  Top quality pieces mostly recovered over the past decade by myself. There is a lot of variety in the specimens from these locations: combination pieces with calcite, parallel growth clusters, intergrown groups, inclusions of anthraxolite, fine skeletal growth crystals, Herkimer diamonds on dolomite crystal matrix, internal shaft scepters and of course those beautiful and very rare fully formed scepters. I won¹t describe the dozens that are white, have some damage, major blowouts discolorations or other problems. No junk here. 

These are nice specimens for the price. Of the hundreds (perhaps thousands) of Herkimer diamonds I have sold over the years, not a one has ever been returned or mention to me in any negative way by a customer. I attempt to keep the price at what would be considered by most a wholesale level.  Sorry about the less than perfect photos.  Of all the minerals we work with these are probably the toughest to get good photos of.

OKK-132    Herkimer Diamond   RESERVED  Fonda, New York.  Collected by Michael Walter.  6.1 x 4.7  x 3.3 cm crystal with one small rider that is deeply embedded on one side.  Lots of internal fracturing but also gemmy clear regions.  This is in excellent shape with no damage.  Not all scuffed or chipped like most larger Herks are.

OKN-848

OKN-845      Herkimer Diamond    Herkimer Diamond Mines and Resort, Middleville, New York.  Collected by Jay Walter, October 23, 2014.  This specimen measures 10 x 9.8 x 5 cm and has a Herk within a vug that is approximately 2.2 cm.  It sits upright nicely  an almost flat base.  This base has a hole going up into the vug that allows for light flow.  The crystal displays nicer than it appears in the photos and if base lit it displays magnificently.  It could be trimmed down more but also has a vug up higher with dolomite crystals in it so it has not been further reduced in size.  Should probably be displayed on right hand edge with the crystal up higher on the piece but I failed to photograph it that way.  No damage and better than the pics indicate.     $80 is a great price on this one!

Back

OKN-563     Herkimer Diamond and Calcite on Dolomite     Treasure Mountain Mine, Fall Hill, Little Falls, New York.  Collected by Michael Walter, 2002, ex.

OKK-139    Quartz (variety Herkimer Diamond)    Treasure Mountain Mine, Fall Hill, Little Falls, New York.  Collected by Michael Walter, summer 2002.  A nice example of once not uncommon material.  Now with the site being closed it is uncommon to see these specimens.  This one measures 6.8 x 6 x 4.4 cm and is a skeletal crystal with black stems at its base.  It is not in the classic scepter form because the stems have been overgrown by the skeletal crystal.  Still a nice damage free quartz from the Herkimer diamond region of New York.  $175

OKJ-705

OKJ-705    Herkimer Diamond    Crystal Grove Mine, near Lassellsville, Fulton County, New York.  Collected by Michael and Jay Walter August 28-30, 2012.  This is one of those large and fine pieces that I usually reserve for my own collection but we need to pay for the summer’s collecting efforts.  There are numerous large crystals to 3.2 cm each.  As is usually the case here the matrix is coated by quartz druse which helps to really make the crystals jump out at you.  It measures 13.4 x 7 x 7 cm.  The crystals are gemmy to moderately so.  One missing crystal low on base, one crystal has a small rub that is not noticeable and there are several areas with minor contact.  All of this is natural.  These things said the condition is excellent for this material and the piece is substantially large with crystals that are also large and nicely displayed.  The base is perfectly trimmed for display.  Nicest piece from a three day dig.  Well priced at $400
