Herkimer diamond is a generic name for a double-terminated quartz crystal discovered within exposed outcrops of dolostone (a sedimentary rock composed primarily of the mineral dolomite, which is magnesium calcium carbonate) They are named Herkimer Diamonds because to the naked eye the sparkling crystals look like real diamonds. These crystals are found in and around Herkimer County, New York and the Mohawk River Valley. Herkimer Country is named after the revolutionary war general, Nicholas Herkimer. Additionally however, the Mohawk Indians native to the area are known as people of the crystals.
Dolostone in this area was deposited about 500 million years ago and the Herkimer Diamonds formed in cavities within the dolostone. Herkimer diamonds became largely recognized after workmen discovered them in large quantities while cutting into the Mohawk River Valley dolostone in the late 18th century. These quartz crystals, which are thought to have formed extremely slowly in small cavities or vugs, they have 18 facets and 6 sides. Herkimer Diamonds have the typical hexagonal shaping of quartz, however, instead of having a termination on one end they are doubly terminated. This is a result of the crystals growing with very little or no contact with their host rock. Such doubly terminated crystals are very rare and this is part of what makes Herkimer Diamonds so popular with mineral collectors.
Crystal healing properties of Herkimer Diamonds
Herkimer Diamonds are said to be the most powerful of all Quartz crystals. Being doubly terminated, they have the ability to not only transmit their own energies, but to receive spiritual energy and to amplify. They are reported to be harder than all other quartz, giving them the strength and durability to handle difficult challenges beyond the scope of other quartz crystals.
