The search for 2022's jewellery star is on - as Katherine goes to Birmingham to meet eight new sparkling contestants to seek out a new gem, as they are each given three and a half hours to create a new earring.
This time round, the sparkling contestants are tasked to come up with an original linked neck-chain, as well as to come up with their own bespoke piece.
In this fourth instalment, the remaining contestants are given the task of creating a Birmingham-themed brooch, and additionally a stylish bespoke ear cuff for an individual client.
In this penultimate episode, the semi-finalists are tasked with creating a best-selling pair of mis-matched earrings from 9-carat gold, as well as a bespoke piece.
The three finalists battle it out with two challenges ahead of them - to create the ultimate sapphire engagement ring, and a strictly sensational bespoke red-carpet necklace. Who will be crowned the All That Glitters jewellery star of 2022?
