Michael Jack is the son of Ray Jack, who has long-been famous for these intricate inlaid pieces. Michael learned well from his father and most people believe he is just as good. There is no shortcut in making these, it's as tedious as it appears. This pendant weighs .8-ounce and is 2.75-inches long (including the fancy bale), and 1.75-inches wide. It ships with a nice 18-inch solid Sterling box chain. Hallmarked "M"
