Feb 20 (Reuters) - Gold prices edged lower on Friday from a record high hit in the previous session, but stayed on track for their eighth straight weekly gain, supported by safe-haven demand on concerns over U.S. President Donald Trump's tariff threats.
Spot gold shed 0.4% to $2,927.89 an ounce by 0501 GMT. Bullion has added more than 1% so far this week, rising to an all-time high of $2,954.69 on Thursday.
U.S. gold futures fell 0.5% to $2,942.
