Tall fish tales are a time-honored tradition. This eye-catching marlin tells its own story. Crafted in highly polished 18K gold, its sweeping fins and tail contrast vividly with a body of gleaming cobalt blue lapis, remarkably similar in color to the strikingly beautiful actual blue marlins that navigate the far reaches of the sea. The similarities end there, as this one has a head studded with glittering round brilliant-cut diamonds and a tiny ruby eye. Marlins are known to put up quite the fight when hooked—don’t let this be the one that got away. Total diamond weight, .32 carat. In 18K gold, it measures 1 1/8 by 3 1/2 inches.
