Our Mission

We want to show you jewellery in a new light, and for you to fall in love with it. It will become your story.

Our Promise





Our Story

Amanda Zuydervelt was born with business in her bones. A natural entrepreneur, she has a flair for spotting a gap in the market, then working with zeal and spirit to fill it with a product she believes in and loves.

Omnēque is one of a kind, a digital platform that specialises in unique pre-owned jewellery. Amanda has always sought to set up businesses that give something back or pay it forward. Omnēque does both. It’s a luxury online marketplace where the best jewellery continues its journey to its next loving owners.

But this marketplace is so much more than just a shop: it is a unique resource for great jewellery. You can get a ring remodelled or commission a bespoke piece; find someone to help you navigate the minefield of auctions, or help you select the perfect piece for yourself or as a gift for a loved one. And this offering has been powered by an elite team Amanda surrounded herself with, including the likes of Joanna Hardy, Vivienne Becker, Josephine Odet and Charlotte Rogers, jewellery experts with many years of combined experience.
