The General Assembly of 1973 designated the emerald as the official State Precious Stone. (Session Laws, 1973, c. 136).

Selection as the State Precious Stone

The Bill to establish the Emerald as the State Precious Stone was introduced by Rep. Margaret Keesee of Guilford county in January of 1973. It received little opposition and was passed in April of 1973.

About the Emerald

An Emerald is a green variety of beryl highly prized as a gemstone. Emeralds are one of the ‘big four’ gemstones (Diamonds, Emeralds, Rubies, and Sapphires) that are most popular for jewelry and commercial use. The beryl’s natural color is clear, but gets its color from small amounts of chromium and vanadium. They will lose their color if heated. Emeralds occur naturally as six sided prisms, sometimes called ‘bolts,’ and are usually elongated with smooth sides.

North Carolina has the only significant emerald deposits in North America.

Emeralds were first found in Alexander County in 1874, and later in Mitchell County (1890) and Cleveland County (1897). Today, these are North Carolina’s three known emerald districts.

North Carolina’s emeralds are found in pockets of quartz veins. Pockets can range from a few centimeters to three meters in length.

An emerald crystal weighing 1869 carats, thought to be the largest ever found in North America, was unearthed in late 2003 at a mine in Hiddenite, near Statesville. A 71-carat stone found on the same property yielded two finished stones--the 7.85 carat Carolina Prince that sold for $500,000, and the Carolina Queen (18.88 carats). Other famous emeralds of North Carolina include the 858 carat “Empress Caroline” and the cut 64.82 carat “Carolina Emperor,” which is styled after an emerald once owned by Empress Catherine the Great of Russia.

Due to their rarity, synthetic emeralds are also produced in the United States through a hydrothermal method, in which aquamarine crystals are placed in a water solution under high temperatures and pressure.

Old folktales attribute many properties to the emerald. It has been said that they can cure dysentery, prevent epilepsy, assist women in childbirth, preserve chastity, and even drive away evil spirits.


The gem hiddenite is a relative of the emerald and is one of the rarest gems in the world. It can be found in very few places, one of which is Alexander County, North Carolina. It was discovered 1879 in the town of White Plains by Dr. William Hidden. Hidden was sent to the area by Thomas Edison to find an alternative material to replace tungsten in light bulbs. He found instead a variety of spodumene never before seen. The stone was named Hiddenite, and the town of White Plains was renamed Hiddenite in its honor. Hiddenite is not mined commercially, but it can be cut as a gemstone.

Thank you for visiting NCpedia and for taking time to share this info!

Best wishes,

yeah, awesome report!


I am actually from hiddenite actually live born an raised here on Hill River Road in Hiddenite. I actually have a lot of questions about the whole subject in general. Like what are the biggest factor to be looking for as far as land terrain an specific rock type an its consistency versus other rocks.. I have natural spring in front of the house which sits back about 200 yards off the rd. The spring lies in the bottom of 2 hills half way downdriveway. would a natural spring be an ideal spot to prosprect?? I've actually seen an abundance of Courts and all types of other routes heck piles of Courts like somebody has placed them there actually I don't know maybe you can give me some insight on what I need to do on furthering my education of what I could do as far as figuring out anything about this whole situation?? I'd love nothing more than bring that Green Beauty out of the ground that I know has been laying is there all these years!!


Any information would be greatly appreciated


I have dug crystals up on that road, The Alexander claim.... there is a recorded emerald that was found in your area....Hiddenite can be found in the creeks... but emeralds are found near clear quartz and green mica.... chromium is what makes an emerald green and it will turn the mica green.... so if you find green mica chances are you might run into an emerald pocket.... maybe in some nice black rock as well


Kind of wondering when did people start to notice and want emeralds like people do now?


The Native Americans probably used them for jewelry and then showed them to the Pilgrims.


This is an interesting thought. Have you found any scholarly articles on this topic that you can share?
