The type of gold under the black finish affects the price. Some processes to electroplate, oxidize, or treat the gold are more costly. The cost of black gold also depends on labor. Despite the black metal and additional procedures to create the black color, the value is in the natural material. The more yellow gold in the jewelry, the more its value grows. Value of Black Gold: How Much Is It Worth?īecause black gold contains real gold, it is automatically valuable. Oxidation can weaken metals, so this isn’t the most desirable method for jewelry people wear daily. When jewelers apply acid to the surface, the yellow gold turns black. Jewelers can also create black gold through oxidation. So, black gold made with femtosecond laser treatments is technically gold altered to capture light rather than reflect it. Scientists recently discovered a laser application that uses high levels of energy to create microstructures that absorb light. It is durable and expensive because it is energy-consuming. This process involves focusing energy on the gold until it turns the desired shade of black. As such, the process is easy to scale and do affordably.Īnother method of turning gold into black gold is through femtosecond laser treatments. Manufacturers use rhodium for other kinds of electroplating. When it comes to choosing black gold, electroplated jewelry is the most affordable. Unfortunately, the plating does wear off, so eventually, the yellow gold shows through the black coverage. Because of the way metals distribute in black gold, it differs from authentic alloys.īlack gold also comes from electroplating, where yellow gold is plated with a black finish using rhodium or ruthenium. A typical alloy mixes two or more metals. With a precise three-to-one ratio of gold and a second metal, the color changes, and the pairing becomes a pseudo alloy. Manufacturers mix yellow gold with another metal, often cobalt. Different alloying metals produce different shades. Along with black, manufacturers can change gold into a wide range of colors. What Is Black Gold?īlack gold is the same yellow gold, but manufacturers use technology to change the color. Black gold looks edgy and stylish, giving jewelry a fresh and modern look that yellow gold can’t provide. Now black gold is the term that defines blackened gold. In the past, black gold was the nickname for oil, especially as people who found it trickling out of the ground made a small fortune - akin to finding gold.
