stals of exceptional clarity. (Michael R. Walter).
3 Inclusions that provide clues to the origins of the Herkimer diamonds are solids (hydrocarbon materials are the most common. They range from small eye-visible particles down to micron-size particles, which, when abundant, can impart a smoky color to the crystals), liquids (salt water or petroleum), gases (most common carbon dioxide). Calcite, dolomite, pyrite, sphalerite and quartz (often in the form of tiny Herkimer Diamonds) are typical mineral inclusions.
4 The Herkimer Diamonds of New York are not a recent discovery. The Mohawk Indians knew about the crystals. They found them in stream sediments and plowed fields. These people were amazed with the crystals and immediately held them in high esteem. They used the crystals as amulets, used them to make tools, and traded them with other tribes. They began to lose interest in the crystals when European glass beads began to arrive in the early 1600s.
5 Although Herkimer County, New York is the location for which these crystals are named, similar doubly terminated quartz crystals have been found in many other locations, including Hungary, France, Italy, Canada, Pakistan, China and others. They have the same appearance but cannot rightfully be called "Herkimers."
6 Sometimes the single crystals can get quite large, but when they do they are heavily fractured, with the field name "goonie". The maximum size for an unfactured single crystalappears to be 4 cm tip-to-tip, although no official information can be confirmed. To be a perfect Herkimer diamond is not just about clarity but about form. Range of color of Herkimer diamonds : clear, white, smoky, champagne, golden and golden-red.
7 The name “Herkimer Diamonds” is a misnomer (A misnomer is a name that is intentionally or inadvertently incorrect. It is incorrect because the crystals called “Herkimer Diamonds” are quartz crystals rather than diamond crystals ) and has been used for over 100 years and is deeply engrained in the language of local people as well as the rock and mineral community. The word “diamond” grabs attention and may imply a higher value to the person who hears it than the word “quartz.” As a result, some people might be misled or confused by the name “Herkimer diamond.”
8 Some of the best places to find Herkimer Diamonds today are located along New York State Routes 28 and 29 near Middleville, New York. (When visiting this area it is important to remember that all land in New York either belongs to the government or is private property. Collecting minerals from government lands is illegal in New York, and collecting on private property always requires permission in advance.) There are several commercial mines on New York State Routes 28 and 29. These include Ace of Diamonds Mine, Herkimer Diamond Mines, and Crystal Grove Diamond Mine and Campground. These mines allow collectors to enter and prospect for a nominal fee. These locations also rent equipment such as rock hammers, wedges, and other small tools. They also have small exhibit areas where you can view and/or purchase specimens.
9 Nice Herkimer Diamonds are highly prized mineral specimens and every mineral collector from all world wish to have them. Also Herkimer crystals are very popular to use in jewelry because they have sparkling clarity of diamond and their natural beauty.
10 Because the first discovery sites were in the village of Middleville and in the city of Little Falls respectively, the crystal is also known as a Middleville diamond or a Little Falls diamond.
