Black Hills Gold Jewelry
Black Hills gold jewelry was first made during the Black Hills Gold Rush (1970) by a goldsmith Henri LeBeauold. He is believed to have dreamed the design of the jewelry while he passed out due to thirst and starvation. The jewelry illustrates grape clusters, vines and leaves and is created in a combination of rose, green and yellow gold.
The make the Black Hills gold jewelry, pure 24 Karat gold bars, stocks of pure silver and copper are used as the main materials. While the metals used to make the jewelry can be obtained from anywhere in the world, the finished jewelry referred to as Black Hills Gold, must be manufactured in the Black Hills, South Dakota, according to a federal judge rule in the 1980s.
The gold that is used for leaves and some other details are of different colors and are obtained when the pure yellow gold (24 Karat) is alloyed with copper to get the pink or red gold (14 Karat), while the gold is mixed with silver to make the 14 karat green.
The resulted gold bars are rolled to various thicknesses for different jewelry. All parts are stamped, using patterns and dies. The gold leaves and different patterns will be added to a cast jewelry base.
The pieces are polished by traditional hand polishing (with the use of a wheel) or by a process, known as “tumbling”. The polished smooth cast pieces are ready for grapes and leaves to be fixed on them.
Several manufacturers use the traditional way to attach the pieces, while others put the solder and components all together on the cast item to be soldered on their own on the oven.
The nearly completed jewelry is cleaned in a gentle acid bath, followed by a high quality standard inspection. The textured or frosty effect is obtained with the technique known as “wriggling” which textures the leaves. Next, the veins of the leaves are manually engraved for an astonishing finish.
All pieces are polished in numerous different steps to obtain the sparkling luster.
