Blokes Discovers $100 Million Sapphire Cluster In His Own Backyard

Many of us would find the remains of a beloved pet digging up our backyards (and thatโ€™s on a good day). For one Mr Gamage โ€“ who just so happens to be a third-generation gem trader โ€“ unearthing the soil beneath his home in Ratnapura, Sri Lanka has led to the discovery of the worldโ€™s largest star sapphire cluster. A sapphire cluster, itโ€™s worth adding, with an estimated value of up to $100 million on the international market.

Weighing approximately 510 kilograms (2.5 million carats) and since dubbed the โ€œSerendipity Sapphireโ€, the cluster was initially discovered by tradies who were there to dig a well. As you can imagine, the geological lottery caused quite the commotion.

โ€œThe person who was digging the well alerted us about some rare stones,โ€ Gamage explains to the BBC.

โ€œLater we stumbled upon this huge specimen.โ€

โ€œI have never seen such a large specimen before,โ€ says renowned gemmologist, Dr Gamini Zoysa.

โ€œThis was probably formed around 400 million years ago.โ€

After notifying authorities, the sapphire cluster underwent a year-long cleaning process to remove all the mud and other impurities. Experts then analysed and certified Gamageโ€™s stones, valuating it at nine-figures โ€“ despite the fact not every stone may be of high-quality.

โ€œIt is a special star sapphire specimen, probably the biggest in the world,โ€ notes Thilak Weerasinghe, Chairman of the National Gem & Jewellery Authority of Sri Lanka.

โ€œGiven the size and its value, we think it will interest private collectors or museums.โ€

Before you head to Bunnings for a few tools and start tearing up your own backyard, however, keep in mind Sri Lanka is the leading global exporter of sapphires and other precious gems; earning over $500 million in exports last year. And incidentally, the area of Ratnapura โ€“ which is actually Sinhalese for โ€œcity of gemsโ€ โ€“ is the countryโ€™s gem capital.

Still, you miss 100% of the shots you donโ€™t take. So do as you wish and see where it takes you.
