NEW YORK — Born in 1896 in New York City, Harry Winston was destined to one day be crowned the “king of diamonds.” His father ran a small jewelry shop and the young Winston soon showed himself to be a quick study. When he was just 12 years old, he spied an emerald being sold as a piece of green glass on a tray of costume jewelry in a pawnshop. To avoid alerting the shop owner, he bought it along with another stone for the grand sum of 50 cents and resold it for $800 a few days later.
