______________________________

The "Herkimer Diamond" locality is situated in the center of New York State, located in the Little Falls, the Mohawk River in the rolling foothills of the Adirondacks.  Geologically, the precambrian meta-sedimentary Grenville formation was intruded by large masses of syenite.  After subsidence during the cambrian, the syenite became a base for marine sediments - basically CaMg(CO3) 2 with silica and organic mater.  These sediments later because the Little Falls dolomite in which the quartz crystals were formed.  Most of the crystals are found in a narrow belt extending from Little Falls in the south to Salisbury (Diamond Hill) and Middleville in the north, although the doubly terminated crystals are found as far away as Lake George, some 50 miles to the northeast.

 

The largest "Herkimer Diamond" on records, measured 14 inches along the c axis and was found at Nose Mountain, Fonda in Fulton County NY.  The highest quality crystals are in the Little Falls and Middleville area.    The reason for so many doubly terminated crystals is somewhat of an enigma to geologists.  One possibility is a nearly simultaneous crystallization of calcite and then quartz in the dolomite cavities and pores.  Many crystals are still found within eroding calcite and many freshly opened pockets contain dozens of loose crystals showing no point of attachment .  Many pockets are covered with a black shiny nitro gent contained hydrocarbon called anthraxolite.  Occasionally flakes of anthraxolite can be found floating on water bubbles within a a clear doubly terminated quartz crystal.


Below we are lucky to share the 'Krista F. Collection'.  Enjoy!

Tidbits:   Herkimer Diamonds are said to be the most valuable and clearest of all quartz and are sought after by collectors.  We are lucky to be near the mines here in New York.  Metaphysically, these stones are known as "attunement" for Reiki and other practices.  They are said to be stones of inner vision and useful in dream work, energy work and meditation.   They, like quartz, can be programmed with your thoughts and wishes.
