Notes: |
This natural, double terminated quartz crystal small but mighty. Herkimer Diamonds were formed by tremendous heat 300-500 million years ago beneath a shallow sea bed of the rock dolomite, now New York state. The dolomite began as limestone and calcite rock, and while still under water, magnesium was added. This new addition created the sedimentary rock called dolomite. Pockets and vugs within the dolomite were filled with fluid rich in silicon dioxide, or quartz, providing the material to allow the clear crystals to form. One explanation as to the double terminations points of Herkimers is that the fluid filled pockets allowed them to form freely, providing the opportunity to terminate on both ends. Another explanation to the double termination's is silica has no attraction to the dolomite rock and avoids attachment to it. Externally it's perfect with a teeny chimney bridge crystal. Internally, a speck of black hydrocarbon adds authenticity and a rich deep hue to this natural double terminated quartz crystal.. |
