A Destination for Precious Things

Omnēque is a luxury online marketplace where the best jewellery continues its journey to its next owners. We are dedicated to giving new life to precious objects at a time when what and how we buy says everything about who we are.

We continually curate an inspiring selection of unique pre-owned pieces authenticated by top industry experts alongside spotlight partnerships showcasing the best collections from contemporary designer-makers. A true home of jewellery, Omnēque also offers a range of services from our concierge including jewellery sourcing, remodelling and bespoke commissions.

Our Mission

With a passion for the craft of jewellery and the stories it tells, our mission is to inspire you to collect and style it in your own individual way.

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

“These gems have life in them; their colours speak, say what words fail of”

Our Story

A love of jewellery and an entrepreneurial spirit is at the core of Omnēque. Co-founder Amanda Zuydervelt has been setting up businesses since the age of nine, when she sold drinks from a wheelbarrow on the golf course near her childhood home.

After that venture was scuppered by overzealous security guards, she suggested to her best friend that they look around their houses to find things to sell in a new roadside location.

When they came across their mothers’ jewellery collections, they knew they had something people would want. They weren’t in business long before their mothers reclaimed their precious things, but the appeal of selling pre-owned jewellery stuck with Amanda and that kernel of an idea from a young entrepreneurial mind eventually became today's Omnēque.

This marketplace was to be 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.
