Independent. Experienced. Passionate.

Nicholas Alexander was founded to offer a unique approach to jewellery – combining the precision of gemmology and diamond grading with a deep appreciation for design, craftsmanship, and personal stories. While we hold a deep respect for vintage and antique jewellery, we are equally passionate about creating timeless new pieces – from classic engagement rings to custom designs with a modern edge. Our role goes beyond sales – we honour the personal and historical value behind every piece we work with, whether heritage or modern.

From bespoke design to trusted resale – all under one roof.

We support every stage in the life of a piece – including sourcing, custom design, expert repairs, valuations, consignment and resale. Each piece we offer, whether newly made or decades old, is selected or crafted with care and authenticated by qualified professionals.
