South Dakota designated "Black Hills gold" its official jewelry on March 3, 1988, a reminder that, by law, only jewelry manufactured in the Black Hills can be sold under the name "Black Hills gold." (Gold is also mentioned in South Dakota's state song.).
Black Hills gold, the state jewelry, is created and manufactured exclusively in the Black Hills of South Dakota. Each design incorporates the traditional motif of grapes and leaves in tri-color combinations of green, rose and yellow gold.
Black Hills gold jewelry is a
type of jewelry manufactured in the Black Hills of South Dakota. It was first created in the 1870s during the Black Hills Gold Rush by a French goldsmith
named Henri LeBeau, who is said to have dreamed about the design after passing out from thirst and starvation. Black Hills gold jewelry depicts leaves,
grape clusters and vines, and is made with alloys of gold with standard yellow gold as well as green and pink gold. In 1980, the 8th Circuit affirmed
an injunction ruling that if a manufacturer was to call its jewelry Black Hills Gold, then it must be made in the Black Hills. The state of South Dakota
designated Black Hills gold as the official state jewelry in 1988.
The designs use grapes, grape leaves and grape stems and are easily recognizable for their distinctive colors. Silver is alloyed with the yellow gold
to produce the green hue, and copper is alloyed with the yellow gold to make the red or pink gold. The jewelry was originally made with South Dakota-mined
gold but in more recent years, since the closure of the Homestake Mine, the gold is sourced elsewhere.
Pure 24 Karat gold bars, and stocks of pure silver and copper are the basic materials. These metals are not required to be mined in the Black Hills.
Pure gold and other precious metal stock can be acquired from anywhere in the world. The finished jewelry known as Black Hills Gold must be produced
in the Black Hills of South Dakota.
The different colors of gold used for leaves and other details are made when the pure 24 Karat yellow gold is alloyed with copper to achieve the traditional
14 karat pink (or red) gold, and the gold is combined with silver to create the 14 karat green gold. The resulting gold bars are then readied for rolling.
The alloyed gold bars are rolled by presses to different thicknesses for different types of jewelry. Each part is carefully stamped, one at a time,
out of the rolled gold sheets using patterns and dies. The solid gold leaves and other patterns are then ready to be added to a cast jewelry base.
The cast pieces are then polished by one of two methods, either traditional hand polishing using a wheel, or a process called "tumbling."
For tumbling: many castings at one time are placed in a tub or cylinder with different sizes and shapes of metal, rubber or other materials in a liquid
solution, then agitated or rotated until they have been polished smooth. These smooth, cast pieces are then ready for the stamped components, like
leaves and grapes, to be mounted on them.
Some manufacturers, such as Landstroms, use the traditional method to attach the pieces, where the stamped components are individually hand-soldered
to the cast gold frame using torches and karat-gold solder. Other factories place the solder and components together on the cast item, leaving several
such assemblies in a soldering oven where they are soldered by the heat of the oven.
The almost-finished jewelry is cleaned in a mild acid bath, then inspected using high quality standards. A finishing technique known as "wriggling"
textures the leaves, creating a textured or frosty effect. Each leaf vein is then hand-engraved for a brilliant, light-catching finish.
Each piece is polished in several different steps to bring out its brilliant luster. If the item has gemstones in its design, it is sent to the stone
setting department for mounting. Finally, a careful inspection completes the process that began with pure 24 Karat gold and finished with a truly unique
and beautiful, handcrafted jewelry item
Peace of the prairies was no more when gold was discovered in South Dakota's Black Hills in 1874. A treaty with the Sioux Indians was broken as an influx of prospectors poured into the Sioux's sacred Paha Sapa, as they called the Black Hills, causing disturbances in the region while creating opportunities and radically transforming the region. The northern plains Indians were driven to war and to their demise.
The 1875 Battle of Little Bighorn was decisive for the region's future, despite the defeat of General George A. Custer. American Indians were forced to cede the Black Hills and accept reduction in their reservation's area. The conflict cleared the way for further development. The last serious Indian-white conflict occurred in 1890; afterwards, barriers to settlement attenuated.
The law designating Black Hills gold as the official South Dakota state jewelry is found in the South Dakota Codified Laws, Title 1, Chapter 1-6, Section 1-6-16.2
