U.S. gold futures GCcv1 jumped more than 1 percent to a high of $1,880 an ounce on Friday after weaker Japanese stocks prompted buying from speculators.

The Nikkei average posted a weekly loss of 2.4 percent and was moving back towards a six-month low hit earlier in the week after U.S. President Barack Obama's jobs package turned out not to provide new buying incentives.
