Gold eased on Tuesday as Asian shares gained strength but the metal continued to stay above $1,300 an ounce as escalating tensions over conflicts in Ukraine and the Gaza strip burnished the metal's safe-haven appeal. Spot gold slipped 0.35 percent to $1,307 an ounce by 0554 GMT. It had gained as much as 0.6 percent in intraday trading on Monday, but failed to hold the gains and closed flat.
