Michael Arnstein, CEO of New York's Natural Sapphire Co., holds a 69-carat sapphire worth over a million dollars on Nov. 17, 2010, in New York. The company has been overwhelmed with orders for reproductions of the sapphire and diamond ring that once belonged to Lady Diana and has now been presented to Kate Middleton after Prince William proposed to her. The original ring is an oval, 18-carat sapphire ring set with diamonds and 18-carat white gold. The reproduction will cost an estimated half-million dollars.
