1. A Star Diamonds Hatton Garden

A Star Diamonds operates from Hatton Garden, London’s historic jewellery quarter. This family-run jeweller specialises in bespoke engagement rings and wedding bands, with a team of goldsmiths, designers, and gemologists who work directly with you throughout the design process. You can book appointments at their Hatton Garden workshop or arrange online consultations if you prefer to start remotely.

Why this place stands out

You get in-house craftsmanship rather than outsourced manufacturing. The team creates each ring from scratch in their London workshop, which means you can request specific modifications and see your design take shape. They offer lifetime benefits including free resizing, polishing, and cleaning for all UK-made pieces. Their family-run approach focuses on capturing your story in the design rather than pushing pre-made options.

Platinum ring styles and options

A Star Diamonds works with platinum 950, the standard for wedding rings. You can choose from classic court profiles, flat designs with bevelled edges, or contemporary patterns. They offer both natural and lab-grown diamonds if you want stones set into your band. The team also creates matching sets if you’re buying both engagement and wedding rings. Every design starts with your preferences rather than a fixed catalogue.

You review 3D renders before they start crafting. They offer complimentary engraving on all rings.

"A Star Diamonds provides platinum wedding rings London couples rely on for bespoke quality and lifetime aftercare."
