It was a feat that made even skeptics believe in the power of charm Pandora bracelets: a selection of 600 charms, in various combinations of gold, silver, wood and glass, cast in intricate shapes and designs, imbued with gems or semiprecious stones, transformed Pandora jewelry sale from a family-run jewelry shop in Copenhagen to a multibillion-dollar international brand. Pandora became the third-largest jewelry company in the world and a stock market sensation was the result in no small part of the customizable Pandora bracelet concept the company introduced in 2000, which allowed customers to chose among its hundreds of charms and combine them.

The revenue of Pandora sale nearly doubled every year, profit margins were among the highest in the industry, and Pandora’s initial public offering on the Copenhagen exchange in October 2010 raised $2.1 billion. It was the fourth-largest European listing of the year. Pandora Jewelry shares peaked at 371.9 kroner, or $67, last January, up 43 percent from the debut price of 210 kroner.
