Monica Vinader Ltd. is a British jewellery brand producing and retailing necklaces, pendants, earrings, rings, and friendship bracelets.

[1] Profitable from 2009,[1] the company secured funding from London-based venture capital firm Beringea in 2010, using it to open their first store on London's South Molton Street.

[8] Since 2016 Catherine, Duchess of Cambridge has been noted by fashion websites for wearing a pair of onyx Monica Vinader earrings many times.

[9][10] Since 2019, Monica Vinader has worked jointly with other creatives in order to launch collaborative collections, first with editor Caroline Issa and subsequently with sustainable fashion advocate Doina Ciobanu.
