Look once at former estate jeweler Michael Kanners's frog cuff links and you'll notice the Burmese jade. Look twice and you'll catch the crown and a cartoonish pair of gold lips. "What I strive for in all my work," says the 37-year-old, now based in Italy, "is a unique design, the finest material, and a bit of wit." Clearly. Other examples are crafted from moonstone and rock crystal (a car with see-through windows) and jasper (books bearing dollar and euro symbols; BUY and SELL on the backs). Kanners's designs have been a hit with men searching for cuff links that are neither overly stuffy nor just another whimsical gimmick. $2,050-$4,350. By appointment only, 917-912-1302.
