With over three decades of experience in fine and antique jewellery, every piece offered by Astoria Auctions is individually vetted and carefully curated for quality, authenticity and desirability.

As qualified gemmologists and diamond graders, holding internationally recognised gemmological diplomas and Fellowship status (FGA), we examine gemstones for identity and authenticity. We assess overall condition, identify visible repairs or alterations, and provide clear, accurate catalogue descriptions wherever possible.

Our expertise extends beyond gemmology to encompass craftsmanship, period, provenance, design and market value. Where appropriate, we undertake further research into provenance and historical context, and ensure all due diligence and compliance checks are completed in line with industry best practice. This ensures buyers can bid with confidence. Every item is selected with a discerning eye, reflecting our commitment to scholarship, integrity and exceptional standards.

Trust is central to everything we do, and is strengthened by our knowledge, qualifications and professional expertise. Wherever possible, certificates are provided and all stones are carefully checked. Repairs are thoroughly examined, and any flaws or restorations that are visible are clearly noted. We also maintain strict standards of confidentiality, ethical sourcing awareness, and regulatory compliance, including anti-money laundering procedures where applicable. Our ethics are founded on integrity, excellence and the highest standards of knowledge, ensuring that client relationships are built on confidence, transparency and long-term trust, and are carefully maintained over time.

With a global reach, Astoria Auctions serves an international clientele of collectors, dealers and institutions, with participation from bidders across Europe, North America, the Middle East and Asia. Our online platform enables seamless access to auctions worldwide, ensuring exceptional pieces are presented to a truly global audience.

Inspired by the falcon of the ancient world, the Astoria hawk represents vision, wisdom and protection. It reflects our belief that true expertise begins with careful observation. Every jewel we present is selected with knowledge, examined with precision and chosen for its quality, character and provenance.

The hawk symbolises vigilance. It represents the ability to observe patiently, discern wisely and act with considered judgement rather than impulse. With a keen and discerning eye, it selects only the exceptional, recognising not merely what is beautiful, but what is truly significant. It reminds us to respond thoughtfully rather than react hastily, to remain objective, and to uphold the highest standards of scholarship, integrity and expertise in every decision we make.

The star above the hawk represents knowledge, guidance and aspiration. Like the stars that have guided travellers and explorers throughout history, it symbolises clarity of purpose, the pursuit of excellence and a commitment to lifelong learning. It reminds us that true expertise is built not only on experience, but on curiosity, continual study and the desire to deepen our understanding.

Together, the hawk and star embody Astoria’s philosophy: that knowledge guides discernment, and discernment leads to wise judgement. They represent our commitment to careful curation, rigorous research and the enduring pursuit of excellence.

Like the hawk, we believe that excellence lies not in seeing more, but in seeing more clearly.
