The collection comprises 380 pieces and is available online and across River Island’s 254 store estate.
The jewellery features hoop earrings and layering necklaces, in addition to a collection of seasonal pieces.
Lorraine Bottomley, DCK’s CEO, said: “We are thrilled to have partnered with River Island to launch this range, which coincided with the reopening of non-essential retail stores across the UK.
“We continue to see increasing demand for bespoke jewellery ranges from both UK and international retailers as jewellery and accessorising is now essential to the fashion savvy shopper.”
Lucy Nutter, buying director at River Island, added: “We are delighted to have forged a relationship with DCK to deliver our jewellery range.
“DCK has unrivalled capabilities and customer understanding within the category, and together we have created a truly unique collection which we believe will really resonate with our customer base.”
