The first discovery of the hiddenite stone was made in 1879 by W. E. Hidden. Samples were sent to Dr. J. Lawrence Smith in Louisville, Kentucky, who determined that the stone Hidden had collected was spodumene. The variety was given the name Hiddenite. Emeralds had earlier been found during ploughing in 1874.
Emerald Hollow MineEdit
One of the major mines in the county is the Emerald Hollow Mine. This a public gem mine located in the Piedmont of North Carolina in Alexander County, specifically in the town of Hiddenite.
At the mine, more than 63 different types of gems and minerals can be found including emeralds, amethyst, sapphire, aquamarine, topaz, garnet, as well as the stone Hiddenite, which is a stone only found in this local area. The ways in which gems can be uncovered in this mine is by sluicing, creeking, or digging. Sluicing is the process of taking a small amount of dirt or soil removed from the mine and sifting through it with a stream of running water known as a sluiceway. As the dirt is washed down the trough, the larger pieces of gems, minerals, and other stones are left in the sifter.
Digging in permitted areas allows for visitors of the mine to dig into the earth to search for veins that may contain gemstones. The use of the creek is a major part of the mine. Guests are allowed to enter the mountain water creek to search for valuable stones.
The mine is attended by an on-site lapidary shop where visitors’ gem stones can be cleaned, finished, and made into jewelry. The Emerald Hollow Mine is owned and operated by Dottie Watkins.
North American Emerald MineEdit
Another major mine is the North American Emerald Mine (NAEM), operated privately. Previously known as Rist Mine, this is a location mined by James K. Hill who is the founder of North American Emerald Mines Inc. At the mine more than 30,000 carats (6.0Â kg) of emeralds have been found, estimated value US$9 million.
For excavating the stones, large, modern, and professional equipment is used to unearth the gems hidden deep within the pits of the NAEM.
Emeralds foundEdit
In 1969, an emerald of 1,438 carats (0.2876Â kg) was uncovered, the largest yet found in North America. The stone was named the Stephenson Emerald in honor of John A. D. Stephenson, a late 19th-century collector instrumental in the discovery of the first North Carolina emerald and the first world discovery of hiddenite.
In 2003, a larger emerald was uncovered at the NAEM by Jamie Hill. It was 1,869 carats (0.3738Â kg) and valued at over one million dollars.
In 2006, NAEM unearthed a yet larger emerald, said to be 10 inches in length.
Adams MineEdit
Also located in the hills of Hiddenite are the Adams mine, formerly known as the Warren mine, the Emerald & Hiddenite mine, the Turner mine, and the Hiddenite mine.
Other discoveriesEdit
In 1882, an emerald crystal of 1,276 carats (0.2552Â kg) was discovered. At the time, this was largest emerald crystal ever found in North America. However, it was stolen from the American Museum of Natural History, NY, in 1950 and never recovered.
In 1971, approximately 9,400 carats (1.88Â kg) of emeralds were found the area. Some of these stones are now displayed in the Smithsonian.
A recent large discovery occurred in 1980 when over 1,500 hiddenite crystals were found in a large underground vein pocket.
