Herkimer Diamond Mineral Specimens

Herkimer diamond mineral specimens come in all shapes and sizes. This one is from Fonda, New York.        An impressive cluster of Herkimer diamond crystals from Fonda, New York.    This cluster of Herkimer Diamonds was unexpected. We did not count on finding pockets until we were about 10 feet down.   

The majority of these specimens are from Treasure Mountain in Little Falls, NY.  Top quality pieces mostly recovered over the past three years by myself. There is a lot of variety in the specimens from this location: 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 wonąt 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.

OKE-021

OKE-021   Skeletal Herkimer Diamond   Treasure Mountain Mine, Little Falls, New York.  4.2 x 2.6 x 1.8 cm.  Small but very interesting and complex.  This grouping of parallel growth crystals is highly skeletal both internally and externally.  Externally the piece almost appears etched.  Internally one of the larger crystals is almost hollow.  One edge has an internal anthraxolite patterning which makes it look like an internal shaft scepter.  Zero damage floater.  A very uncommon example.  90$

EA-130

EA-130 Herkimer Diamond Treasure Mountain, Little Falls, NY. This may be the best cluster I have seen from Treasure Mt. to date. It is composed of two larger crystals (approx 5.5 cm each) and 5 additional rider, or sister, crystals lightly attached to their sides. It is a reassembled, self collected group that would be described as floaters. Only attachment is a couple dolomite crystals on the bottom side which are only a few millimeters in size. Typical inclusions and top shelf aesthetics. 500$

 



OKA-782E Intergrown pair of crystals with moderate anthraxolite inclusions. Crystals are 4 and 4.9 cm each. Very nice. 70$



OKA-784 Skeletal Herkimer Diamonds. Treasure Mt. is quickly becoming famous for its small, beautifully formed skeletal crystals. These are, in my opinion, better than the skeletal Herk crystals from any other location. Similar to the ones in Rocks and Minerals Magazine...these are similar to the one in the American Museum of Natural History....at a fraction of the cost.

OKA-784B Pair of crystals...5.5 x 5 cm overall. Slightly smoky. 65$

 

OKA-869 Herkimer Diamond Ace of Diamonds, Middleville, NY. 6.8 cm crystal with a 3 cm rider crystal. Both have some internal fracturing but less than normal. Rider is partially skeletal and both of these double terminated crystals are completely damage free. The big crystal has a very light smoky phantom. Very nice example at a wholesale price.  85$



OKA-870 Herkimer Diamond Fonda, NY. This is a 10 x 8 cm cluster composed of 4 large Herks up to 7.5 cm each. The cluster is reassembled and has some damage. The largest crystal is repaired and missing a piece. Sounds unattractive but the piece is still quite handsome. This piece should be displayed on edge with damaged crystal down to look its best. 100$

 

 

 

OKA-885

OKA-885 Herkimer Diamond Treasure Mountain, Little Falls, NY. Cluster of three diamonds up to 4.2 cm in size. Entire piece measures 5.4 x 4.2 cm. Chips on base of piece are hidden from view from any angle. Minor anthraxolite and typical fracture inclusions. Excellent display specimen. Reassembled. Nice price.... 40$

 



 

OKA-886

OKA-886 Herkimer Diamond Treasure Mountain, Little Falls, NY. Impressive group of three unusually clear diamonds sit on the point of a typical diamond. The entire specimen is over 7 cm long and stands up wonderfully, I would be hard to find a better display piece. Clear cluster has been reattached to base diamond. 50$
