PRECIOUS-Gold dips on steady dollar, but political tensions support

* Gold heads for a third straight quarterly rise

* Silver set post its worst quarter in three

* Platinum to post worst month since September

* Palladium on track for worst quarter since end-2015

(Adds more analyst comment, updates prices, changes dateline from BENGALURU) LONDON, March 29 (Reuters) - Gold prices dipped on Thursday as the dollar held its strong gains from the previous session, but simmering tensions over Russia and a potential trade war offered support. Gold posted its biggest one-day percentage fall in nearly nine months on Wednesday after robust U.S. data lifted the dollar, which steadied at those strong levels on Thursday.

Spot gold had slipped 0.1 percent to $1,323.51 per

ounce by 1106 GMT, after hitting a low of $1,322.50 earlier in the session, its lowest since March 21.

U.S. gold futures for April delivery were down 0.02

percent at $1,324 per ounce. Spot gold dropped 1.5 percent on Wednesday, the biggest one-day percentage decline since July 3, 2017. "I don't see gold falling much further from here given the continued geopolitical tensions," said Carsten Fritsch, commodity analyst at Commerzbank in Frankfurt. "There was an easing of tensions in the Far East regarding North Korea, but there's still tension between the West and Russia... this can boil over again and support gold." North and South Korea will hold their first summit in more than a decade on April 27, South Korean officials said on Thursday, after North Korean leader Kim Jong Un pledged his commitment to denuclearisation as tensions ease between the old foes. But Moscow has threatened to take retaliatory action after the United States and other Western countries expelled more than 100 Russian diplomats over the poisoning of Russian former double agent Sergei Skripal and his daughter in England with a military-grade nerve toxin. Concerns about a global trade war have eased but that does not mean it is over, said Brian Lan, managing director at dealer GoldSilver Central in Singapore. Gold, often seen as an alternative investment during times of political and financial uncertainty, was on track for a third straight quarter of gains, having risen nearly 2 percent so far.

In other precious metals, spot silver dipped 0.1

percent to $16.24 per ounce after falling to $16.20, its lowest in one week. Silver was on track to post its worst quarter in three.

Platinum rose 0.5 percent to $935.80 per ounce, after

hitting a near three-month low in the previous session. The metal was down about 5 percent so far this month, on course to post its worst month since September.

Palladium , up 0.3 percent to $969.10 an ounce, was

set to fall over 7 percent this month, the steepest drop since December 2016. For the quarter, the metal is down more than 8 percent so far, its worst since the quarter ended December 2015.
