At Darling, I spent 30 minutes raking my fingers through a drawer stuffed with costume jewelry. Finally, I fished out one of the more ornate versions, dipped in eighteen-karat gold with a sizable green stone. Though Darling’s shopgirl couldn’t explain much about the quality of the stones, she did rave about how all of the rings were inherited from Woolworth’s 1997 closing. And at only $10, I wouldn’t mind polishing it up with a little soap and water. 1 Horatio St., at Eighth Ave.; 646-336-6966.
