(IDEX Online) - A British gin company is giving away diamonds to customers who buy a bottle with a lucky cork.Whitley Neill says it wants to "reignite the age-old tradition of handing down heirlooms".It's doing so by presenting winners with what it describes as "lab-created round cut diamond of D, E, F or G clarity with a minimum carat size of 0.4 mm".The 15 prizes have a combined value of $32,000, or ?2,100 each. Winners with a lucky code printed on the cork of its Distiller's Cut London Dry Gin can claim their prize.The distillery says 43 per cent of British adults don't believe they own anything of true sentimental or monetary value that they could pass on.Founder Johnny Neill said: "As a family brand, whose distilling knowledge has been passed down through eight generations, we value the importance of heritage and legacy."The prizes are non-transferable, non-exchangeable and no cash alternative will be given.
