Serendipity Sapphire - Worlds Largest Sapphire Cluster

Dr Gamini Zoysa: Sri Lankan Gemmologist Weighs In on the World's Largest Sapphire Cluster

When news of the world’s largest blue sapphire cluster broke in 2021, it quickly captured the attention of both the global media and the gemmological community. The massive stone, found in a backyard in Ratnapura, Sri Lanka, made headlines for its size, rarity, and the remarkable story of its discovery. Among those called in to provide expert analysis was Rough Cut Ceylon's very own Dr Gamini Zoysa.

An Expert Voice

Though he was not directly involved in the discovery, Dr Zoysa was later brought in to assess the sapphire, and his expert perspective was sought to help the public and collectors alike understand the importance of this unique Ceylon sapphire formation.

Dr Zoysa was interviewed by several international news outlets, including the BBC, which featured his remarks at the top of its widely circulated article on the find. His insight helped explain the potential origins and geological significance of the Sri Lankan blue sapphire cluster. He noted, “I have never seen such a large specimen before. This was probably formed around 400 million years ago.”

The Serendipity Sapphire

Named the Serendipity Sapphire, the cluster weighs around 510 kilograms—equivalent to roughly 2.5 million carats—and was uncovered purely by chance during work on a well. It took months to clean and inspect the stone properly, and only after this process could experts like Dr Zoysa assess its composition and value.

As a seasoned gemmologist with a strong presence in Sri Lanka’s gem trade, Dr Zoysa provided geological context and contributed to the broader understanding of how such a significant blue sapphire cluster might form. His commentary added clarity to the global coverage and reinforced the reputation of Sri Lankan blue sapphires as some of the finest in the world.

Bringing Attention to Sri Lanka’s Gem Heritage

Dr Zoysa’s involvement in the media coverage highlights not only his standing as a knowledgeable figure in the field but also the continued relevance of Sri Lanka’s gemmological expertise. The discovery of this monumental Ceylon sapphire cluster served as a timely reminder of the country’s deep-rooted legacy in producing world-class blue sapphires.

His measured analysis ensured that the story remained grounded in scientific and historical context, even as it captured international imagination.
