Our parent company Niche Jewellery has been operating in Essex, London and Suffolk since 2005. A family run jewellery business, we work with leading jewellery brands alongside developing our own jewellery designs.

Our customers wanted simplified, transparent information about diamonds and wedding jewellery. So we listened. We're here to help with the honest truth about diamonds and how to get the best engagement ring, wedding ring or eternity ring for you.

Choose from our delightful selection of simply stunning diamond engagement, wedding and eternity rings.

Or let us guide you through the process of designing your own ring, acting as your advocate the whole way.

How we got here

We've always loved jewellery. From humble beginnings working with antique jewellery and emerging designers, through more than a decade of owning and running big brand franchises like Swarovski and Pandora.

We're now wholly focused on our independent jewellery boutique in Leigh-on-Sea which includes the stunning diamond caspule collection you see here.

With plenty of experience, diamond expertise including training with De Beers, and a friendly can-do attitude, our approach is a breath of fresh air.

We're not a closed doors establishment with a doorbell. We're a fresh and modern store with a dedicated area for trying and designing diamond rings.
