Notes: |
This dolomite rock holds a Herkimer crystal in a tight
vug. The vug has a coating of dark druse.
Several other vugs are present as well.
Although clarity is fair, the 17x10 mm Herkimer quartz is
double terminated with good definition.
The mineral dolomite began as limestone and calcite rock.
When the rock was still beneath the sea, magnesium was
added. This addition of magnesium created the sedimentary
rock of dolomite along with the pockets where the quartz
crystals grew. These fluid filled pockets allowed the
Herkimer Diamonds to form freely, giving them the
opportunity to form terminations on both ends. Some
vugs are filled with many crystals, others are empty.
