LONDON: Gold prices rose one per cent on Tuesday, reflecting gains across the precious metals, as the euro's climb versus the dollar made assets priced in the US unit more affordable for holders of other currencies.

Platinum also climbed 2.9 per cent to a one-month high at $1,462.50 an ounce in gold's wake, taking further support from reports that South African power utility Eskom had warned of a power shortage. The republic produces around three-quarters of the world's platinum.

Spot gold was up one per cent at $1,626.70 an ounce at 1040 GMT, while spot platinum was up 2.5 per cent at $1,457.49 an ounce.
