LONDON, Feb 7 (Reuters) - Pandora, the world's biggest jewellery maker, is aiming for organic revenue growth of 6%-9% in 2024, it said on Wednesday, after strong sales of its silver charms and bracelets drove its share price to more than double since the start of last year.

The company announced a share buyback programme of up to 4 billion Danish crowns (about $577 million) after confirming strong fourth-quarter revenue and earnings.

Pandora, which sells its jewellery in more than 100 countries, has been a rare bright spot among retailers and brands targeting aspirational consumers with affordable luxury items. ($1 = 6.9329 Danish crowns) (Reporting by Helen Reid; Editing by Tom Hogue and Savio D'Souza)
