A diamond wholesaler visiting Florida reported the theft of $400,000 worth of loose gems in what could amount to a well-orchestrated crime or the case of an ordinary burglar who got incredibly lucky, police said on Wednesday. Jain Rajesh, 47, of New Jersey told police he left the diamonds in a red bag in his Orlando rental car for 13 minutes on Monday evening outside a buffet restaurant and the bag and diamonds were gone when he returned.
