Common rings. These rings are square often with checker board design s typically worn on the third finger but sometimes also on the fourth finger. The checkerboard design is a remainder of the magic quadrant found on jewelry all over the middle east used by the Arabs but also by the Jews (Kaballah). These magic quadrants and books to make the the quadrants and decipher them are particular common in the Yemen. See also antique books section. The slide-show contains ten examples of this type of ring, including a rare "tree-of-life" ring and an "octagonal" ring with 8 sides.
