History of Arkansas Diamonds
John Huddleston’s Discovery in 1906
In 1906, a farmer named John Huddleston made a groundbreaking discovery on his property in Arkansas.
He found two gem-quality diamonds, marking the first time diamonds were found in North America outside of a kimberlite deposit.
The area where John Huddleston discovered these diamonds eventually became known as the Crater of Diamonds.
Huddleston’s unexpected discovery attracted investors and mining companies to the area, and during the early 20th century, various mining operations tried to extract diamonds and other minerals from the site.
While they were successful in unearthing more diamonds, the operations faced numerous challenges, including financial difficulties and legal disputes.
Crater of Diamonds State Park
Due to its unique geological significance and rich history, the location of Huddleston’s diamond discovery was transformed into the Crater of Diamonds State Park in 1972.
The park allows visitors to explore the area and search for diamonds themselves.
It boasts a reputation for being the only diamond-producing site in the United States open to the public.
Over the years, thousands of diamonds have been found at the park, with some particularly notable discoveries.
One of the most famous finds is the Amarillo Starlight Diamond, a 16.37-carat white gem discovered in 1975 by W.W. Johnson from Amarillo, Texas.
The diamond was cut into a 7.54-carat marquise shape, further increasing its value.
Arkansas diamonds hold an intrinsic value beyond the mere monetary worth of the gems. The history and legacy left by John Huddleston’s 1906 discovery continue to captivate visitors to Crater of Diamonds State Park, making these precious stones exceptionally valuable in a cultural and historical context.
Diamond Formation in Arkansas
Volcanic Pipe and Lamproite
In Arkansas, diamonds are primarily found at the Crater of Diamonds State Park. The diamonds here are formed within a unique geological structure known as a volcanic pipe.
This pipe consists of a deep and narrow opening in the earth’s crust, allowing magma to flow up from the mantle.
The volcanic pipe found in this region is composed of a rare rock type called lamproite, which is essential for the formation of diamonds.
Lamproite is a peculiar igneous rock that contains high levels of magnesium and potassium, making it a suitable environment for diamond formation.
Magma and Mantle Processes
The formation of diamonds in Arkansas started more than three billion years ago, as a result of carbon being subjected to extreme heat and pressure within the Earth’s mantle.
During this time, the carbon crystallized into a stable form, resulting in the creation of diamond crystals.
These diamonds, along with other mantle materials, were transported upwards through the volcanic pipe and eventually erupted onto the Earth’s surface as magma.
As this magma cooled and solidified, the contained diamonds were left behind, embedded in the surrounding lamproite deposits.
The geology of the Crater of Diamonds State Park has proven to be a rich source of diamonds. Tourists and visitors have managed to discover over 1,000 precious stones in the park over the years.
While not all Arkansas diamonds are of exceptional monetary value due to their small size or relatively low quality, some notable gems have been found in the region, such as the impressive 40.23 carat Uncle Sam Diamond.
Regardless of their market value, Arkansas diamonds hold significant geological and historical importance, forming a unique part of the state’s cultural heritage.
Types and Colors of Arkansas Diamonds
Arkansas is known for its unique diamond deposits, found primarily in the Crater of Diamonds State Park. These gemstones come in a range of colors, adding to their allure and value. This section will discuss four common colors of Arkansas diamonds: white, brown, pink, and yellow.
White Diamonds
White diamonds are the most familiar and highly sought-after type of diamond. In Arkansas, these stones typically display a sparkling translucent appearance and are valued for their traditional appeal. White Arkansas diamonds have occasionally been found at the Crater of Diamonds State Park, with a notable example being a 1.16 ct type IIa diamond discovered in 2020.
Brown Diamonds
Brown diamonds, sometimes referred to as “chocolate” diamonds, are another color variation that can be found in Arkansas. These diamonds possess a warm, earthy hue which has gained popularity in recent years. The color in brown diamonds is caused by internal graining within the crystal structure. While not as commonly known as white diamonds, brown diamonds from Arkansas can still be considered valuable depending on their size and quality.
Pink Diamonds
Arkansas pink diamonds are extremely rare and highly valued for their romantic and striking appearance. The pink color is caused by the distortion of the diamond’s crystal lattice, which affects how light is absorbed and reflected within the stone. Finding a pink diamond in Arkansas is an extraordinary occurrence, making them highly prized by collectors and enthusiasts alike.
Yellow Diamonds
Yellow diamonds, or “canary” diamonds, are another uncommon color variety found in Arkansas. The yellow hue is caused by the presence of nitrogen within the diamond’s crystal lattice. These vibrant stones are sought after for their distinctive appearance and rarity. Although not as rare as pink diamonds, yellow diamonds from Arkansas are still considered valuable and are a testament to the state’s diverse diamond resources.
Arkansas Diamond Value and Quality
Carat Weight and Size
Arkansas diamonds, found in the Crater of Diamonds State Park, hold value depending on their size, quality, and color. The carat weight of a diamond is a significant factor in determining its worth. Arkansas diamonds have been discovered in various sizes, with the largest being the Uncle Sam Diamond, weighing in at 40.23 carats. Diamonds are priced per carat, so larger stones may fetch a higher price.
Color
Arkansas diamonds can be found in different colors, including white, brown, and yellow. The value of a diamond typically increases with decreasing color or increasing transparency. Colorless diamonds are considered the most valuable and are rarer to find. Although most diamonds discovered in the area are not colorless, some high-quality colorless specimens have been found, increasing the overall value of Arkansas diamonds.
Clarity
Clarity refers to the presence of internal and external imperfections, also known as inclusions and blemishes. Flawless diamonds are exceedingly rare, and Arkansas diamonds are no exception. However, some relatively clean diamonds have been discovered in the state, such as the Strawn-Wagner Diamond, which was graded as “perfect” by the American Gem Society. Higher clarity grades generally result in higher valuations for diamonds.
Cut
The cut of a diamond affects its appearance, brilliance, and overall desirability. While the rough diamonds extracted from the Arkansas soil may not initially showcase their full potential, skilled artisans can cut and polish them to optimize their value. A well-cut Arkansas diamond will have better proportions, symmetry, and polish, which will directly impact its final price in the market.
