Charles Fish, the jewellery shop known for showcasing emerging, established, and high street brands, is holding a very exciting campaign with very shiny rewards. Called "Finders Keepers", customers are taken on an actual treasure hunt, where the booty is sparkly bling, maybe a Cartier watch or two, and jewellery by designers like Shaun Leane, Michael Kors, and Missoma. By following and deciphering cryptic cues on social media and the company's website, customers will have to search for a special piece with a hidden hallmark. Once found customers have a chance of keeping the drool-worthy piece. Finders Keepers indeed.
