With showrooms currently in London and Cheshire, jeweller Steven Stone is reopening its doors in Manchester city centre in November.
To celebrate the opening, a five-day treasure hunt is set to take place in the city, giving shoppers the chance to find and keep a one-carat lab-grown diamond with a retail value of £5,000.
Every day from Monday, 1 November to Friday, 5 November at 12pm the jewellers will reveal consecutive digits of the postcode location where the prize is hidden.
For each day of the week a new digit will be unveiled, along with a cryptic clue, in a bid to draw diamond hunters closer to the prize.
On the final day (Friday, 5 November) those signed up to take part will receive an exclusive email with one final clue.
Whoever gets their hands on the diamond can have it set into a piece of jewellery worth up to £600 – whether it’s an engagement ring, pendant, or a special Christmas gift for a loved one.
Creative director Maxwell Stone said: “We are delighted to be opening our new showroom – and what better way to celebrate than to give one lucky person the chance to seek this one-of-a-kind gem.”
Managing director, Zack Stone, added: “We can’t wait to finally open our doors and spread the word with our exciting treasure hunt.
“Everyone deserves a diamond, so whether you want to pop the question to your partner or give your mum a gift she’ll never forget, this is your chance, so keep your eyes peeled next week.”
