The square with the capital letter "E" in the middle, often found next to the "14k" gold mark on jewelry, typically signifies that the piece is made of 14-karat gold and has been evaluated or certified by a specific assay office or jewelry manufacturer. The "E" may represent the initials of the manufacturer or a hallmark that indicates quality assurance. This mark helps consumers identify the authenticity and quality of the gold content in the jewelry.
