The marking “14kp” signifies that an item is composed of 14 karat plumb gold. This designation indicates the gold content is precisely 14 parts gold to 24 parts total alloy, which translates to 58.3% pure gold. The “p” stands for “plumb,” assuring the gold content meets or exceeds the 14-karat standard. For example, a ring stamped “14kp” guarantees its gold content is at least 58.3% pure gold.
The use of plumb gold offers assurance to consumers regarding the fineness of gold articles. Historically, gold could be alloyed with other metals to enhance durability or modify color. The “plumb” designation provides a standard of purity, preventing deceptive marking practices and fostering consumer confidence. Its application in jewelry manufacturing provides a balance between gold content, durability, and affordability.
