Approximately a dozen discovered Samaritan rings have been recorded so far in scientific literature.
"This ring constitutes an important addition given the assemblage in which it was discovered," the archaeologists said.
The site once served as the agricultural hinterland of Apollonia-Arsuf, which is located west of the excavation area and what is today the Apollonia National Park.

Excavations conducted there from the 1950s until the present indicate that the site was inhabited continuously for more than 1,500 years - from the Persian period in late 6th century B.C. until the end of the Crusader period in the 13th century.
Populated by both Christians and Samaritans during the Byzantine period, Arsuf featured industrial quarters with wine presses, olive presses, plastered pools and kilns for the productin of raw glass.
The site was conquered by the Crusaders in 1101 and by the middle of the 12th century was turned over to the one of the aristocratic Crusader families, becoming the center of a feudal manor. In 1241 a fortress was built, and in 1261 control of the fortified city was handed over to a Christian military order called the Kinghts Hospitaller.
