Turning Talk Into Sales: David Wirtenberg loves to talk. "I could talk your ear off," he says. "I love what I do. I'm a very passionate person." His ability to make sales, and his prior experience in sales for Bear Stearns and Auto Data Processing, helped him build his business from scratch in 2003. His father-in-law became his inspiration and behind-the-scenes mentor. "He said, 'Let's see if we can sell jewelry on the internet,'" Wirtenberg recalls. "I went to 47th Street in Manhattan. I knocked on every door. I didn't know anything about diamonds at the time. I was looking for suppliers, for an education, anything." He ended up buying a couple of diamond rings, and he immediately sold them for a profit on eBay. "I thought, 'This could be something.'"
