Pandora is celebrating the ring stacking craze with a fantastic 3 for 2 offer.

The in-store promotion launches tomorrow, Thursday May 22, in which customers will be given the chance to buy two rings and get a third for free! In the promotion, the cheapest ring is free.

Pandora is also launching an online campaign #MyRingsMyStyle. The new project will see the brand collaborate with Angela Scanlon and Jameela Jamil to promote their collection of sterling silver and 14ct gold stacking rings.

@PANDORA_UK followers can tweet images of their own ring stacks in iconic Irish locations, using #MyRingsMyStyle in a user generated content led campaign which will run from Thursday 22 – 26 May 2014. 

The individual with the most creative ring stack will win their own photoshoot, in addition to a night's stay in a top London hotel and £500 worth of rings.

The Pandora national in-store 3-for-2 rings promotion runs from Thursday 22 to Monday 26 May 2014.
