Great with Magen David Engraved Israel stainless ring.

The Star of David is known in Hebrew as the Shield of David or Magen David (Hebrew מָגֵן דָּוִד or מגן דוד without nikkud, pronounced [mɔˈɣen dɔˈvið] in Tiberian Hebrew (the dialect of the Masoretic Bible), often transcribed Māḡēn Dāwīḏ by Biblical Hebrew linguists, and pronounced [maˈɡen daˈvid] in Modern Hebrew, as well as Mogein Dovid [ˈmɔɡeɪn ˈdɔvid] or Mogen Dovid in Ashkenazi Hebrew and Yiddish). The Shield of David is a generally recognized symbol of Jewish identity and Judaism.[1] The Menorah, the candelabra of seven oil lamps from the Temple in Jerusalem, is a more ancient symbol of Jewish identity.[2][3]
