STORY: Jeweller Pandora is shifting to platinum-plated products to reduce its exposure to wild swings in the silver market .
It's after a speculative frenzy sent the metal's price to a record high over the past year.
The Danish company's share price has become highly sensitive to sharp moves in silver.
Last week's plunge in the metal sparked a rally in the stock.
New versions of Pandora's best-selling charm bracelets will ditch sterling silver for a trademarked alloy base plated with platinum.
Platinum trades at about $2,000 an ounce, far above silver.
But Pandora will use less of it, making the final product cheaper to manufacture and easing pressure on margins.
Pandora's shares gained more than 5% after the announcement.
The world's biggest jewellery brand by items sold, sells silver charm bracelets from $80.
It has limited room to raise prices as its core customers cut back on non-essentials.
Late on Wednesday, it reported fourth-quarter organic revenue growth of 4%, in line with forecasts.
