Yellow Gold used in jewelry making is a gold alloy mix that consists of combining gold, copper and silver. Yellow gold purity is also measured in karats. Yellow gold is the only type of gold that can be used in jewelry making as 24-karats.

In terms of gold jewelry, the fineness of gold is designated in karats, which is commonly abbreviated with "kt" or "K." Base metals are the more common metallic elements, like copper, zinc, and nickel, that are used to alter the appearance and/or durability of the alloy.

Jul 10, 2018 · Pure gold is mixed with other metal elements while in the molten state to create alloys with different properties such as strength and various colors. The most common type of gold alloy is yellow in color and contains silver and zinc. The resulting material is more durable for long-lasting jewelry that is easy to care for.

Gold wires are generally composed by of gold (15–65 wt.%), copper (11–15 wt.%), silver (10–25 wt.%), palladium (5–10 wt.%), platinum (5–10 wt.%), nickel (1–2 wt.%), and traces of zinc. Table 20.7 summarizes the advantage and disadvantages of these wires.

Apr 12, 2017 · Metals Used in Gold Alloys Jewelers use metals such as copper, silver and nickel to create alloys, and the choice of metals affects the resulting color. The lower the karat number assigned to a particular alloy the less gold or yellow the alloy will appear.

Alloys used in jewelry making range from 9-karat gold, approximately 37% pure gold, to 24-karat gold. They are required to be stamped and hallmarked according to purity. A newer alloy becoming popular on the jewelry scene consists of 99% gold and 1% titanium.

Alloys are, therefore, useful metals for jewelry. They increase the variety of metals that can get used. There are different karats for gold, thanks to the base metals added to the gold itself. With silver, the result is sterling silver, with the added base being mainly copper.
