Magic Jewelry, and its sequel Magic Jewelry 2, are both NES games released primarily in Asia. Both games were likely unlicensed titles (Unl), indicating they were not officially produced or distributed by Nintendo.  Gameplay details are vague, but these titles probably involved puzzle or matching gameplay, where players manipulated jewels or similar items, as suggested by the title.  The actual mechanics and game objectives remain largely unknown due to limited information about them available, especially in English-language sources.  Information regarding the developers and publishers of these unlicensed titles is scarce.
