Just about 5/8” in width, crescent form with the tips touching. The field recessed both sides and the front with a niello line below center. Niello was used by the Romans and popular in the medieval period including on Viking jewelry, though it is rarely found intact and this is the first we have offered. This example is professionally refurbished with the 24karat gold overlay restored, on a modern gilt Sterling silver 18” chain and gift boxed with a certificate of authenticity. As expert navigators, the constellations signified mystery and power to Vikings. The Moon was personified as Mani, brother to Sol the Sun, and is abundantly represented in Norse literature. Lunar pendants were worn as pectorals as well as suspended from belts, other clothing, and horse harnesses.
