Final answer:
The marking '14K SCC' on jewelry usually indicates that the piece is made of 14 Karat Solid Gold, where '14K' specifies the purity of the gold and 'SCC' likely represents the maker's mark.
Step-by-step explanation:
The marking "14K SCC" on jewelry typically stands for "14 Karat Solid Gold," with the SCC representing the manufacturer's stamp or trademark. This means that the piece of jewelry is composed of 14 parts gold and 10 parts other metals, totaling 24 parts for the entire compound. The 14K indicates the purity of the gold, which is 58.3% pure gold. This is a common standard for gold jewelry in the United States.
