This is a 14K gold Messianic Star of David Pendant. I believe it was bought at Kay's Jewelry but not sure. Many Jews, who have converted to Judaism, select to wear this pendant. The symbolism is also worn by Christians who wish to trace their root connections to Christ, who was a Jew. Messianic Judaism is a modernist and syncretic movement of Protestant Christianity that incorporates some elements of Judaism and other Jewish traditions.
