March 14, 2014 -- intro:As the region of Crimea votes this weekend whether to secede from Ukraine, Russia's benchmark Micex index has dropped more than 10 percent.
Russia's 10 wealthiest individuals have lost an estimated $6.6 billion between their stock holdings, reports research firm Wealth-X, which collects information on ultra-high net worth individuals.
The country's richest man, Alisher Usmanov, who has holdings in telecommunications, mining and other businesses, lost an estimated $1.7 billion in a week, Wealth-X estimates.
But the richest have been largely silent since the crisis began. "Many inside Russia’s large corporations are no doubt supportive of Mr. Putin’s moves in Crimea, which are widely seen here as correcting a historical error made by the Soviet leader Nikita S. Khrushchev, when he transferred Crimea to the Ukrainian Soviet Socialist Republic," writes the New York Times. "If corporate leaders are complaining, they are doing it quietly."
Here's how Usmanov and nine other of Russia's wealthiest population fared, according to Wealth-X.
