All That Glitters: Britain's Next Jewellery Star

The first challenge is the Bestseller, where they make three silver bangles, before they face the Bespoke challenge and a real client. This week, Ben wants a pendant necklace for his mum to wear to Buckingham Palace when she collects her MBE.

The jewellers have to prove their worth with a chain collar that everyone will want, before taking on a commission for a real client, Chris, who wants a sweetheart brooch for his officer wife Kelly to take on her next tour of duty.

Six up-and-coming jewellers return to the workshop. This week, it's all about glitz and glamour as they try to make a bestselling cocktail ring before designing a bold bib necklace for drag queen Amrou to wear to their first solo show.

Katherine Ryan welcomes five up-and-coming jewellers back to the workshop to continue their quest to impress two of the biggest names in the business. They are tasked to make a pair of identical hoop earrings which could be a bestseller, before welcoming real world client Zeynap, who wants a gold locket to give to the woman who saved her mum's life.

It's all about the sparkle as the four up-and-coming jewellers work with precious gemstones. This time, they are challenged to make an encrusted cuff bracelet before making the ultimate symbol of love: an engagement ring for couple James and Clare.

It's the grand final, and the three finalists return to the workshop to battle it out for the title. To win, they'll have to make two pieces of truly outstanding jewellery: a pair of pearl earrings that could be a bestseller and a bespoke maang tikka, the wedding headpiece for bride Nikki.
