The Platinum Guild International has teamed up with Allure magazine to offer future brides and grooms sets of platinum wedding rings.
 
Soon-to-be-married couples are being encouraged to send details of how they popped the question to the competition to have a chance of winning the luxurious bands from Novell Design Studio.
 
Allure readers will vote for the most romantic and unusual stories and select four to win the prizes.
 
People are encouraged to vote for the tales which "inspire you, make you laugh, get you teary-eyed or do all three".
 
Novell specializes in customized wedding bands which suit customers' lifestyles and tastes, with many of its rings coming in various styles, finishes and widths.
 
Many celebrities sport platinum engagement or wedding rings, including Mariah Carey, whose Jacob & Co band was designed especially for her and features a light pink ten-carat emerald-cut center stone surrounded by 58 intense pink diamonds.
 
Beyonce, Grey's Anatomy star Katherine Heigl and Jennifer Lopez also model luxurious platinum bands.
