Ekanites are still found in gem gravels from the Sabaragamuwa valley. In recent times there are three reported deaths due to keeping ekanites at close proximity to three gem dealers. Being the discoverer of the gemstone Mr Ekanayake has never complained about any unusual disorders as he was very careful about handling and safe ...

Ekanites may also display chatoyancy (cat’s eyes) as well as Tyndall scattering. Small, crystalline (non-metamict) ekanites have been found in Canada. Sources. Sri Lanka has produced most known ekanites, as translucent green pebbles from gem gravels in Eheliyagoda and in placer deposits from Okkampitiya.

Item Description. Ekanite is an extremely rare gem, and is relatively "new" to the gem world as it was only discovered a little over 50 years ago. Ekanite is one of the few radioactive gems as it contains Uranium and Thorium content. Nonetheless, these gems are highly sought after by collectors, and any time you can find a stone that's over 1 ct, it definitely increases the value of the stone ...

Nonetheless, these gems are highly sought after by collectors, and any time you can find a stone that's over 1 ct, it definitely increases the value of the stone as opposed to one that's less than 1 ct. Most Ekanites are brown in color, but this gem has an evident green color. This stone is only very very slightly included with a "Marquise" cut.

Although official reports indicate that there is now virtually no production from the Umba River region, mining of both primary deposits and alluvial gravels continues, and is now done with the help of bulldozers and backhoes (figure 11).This level of activity, and the extent of gem trading in nearby villages and towns, suggests that economic quantities of gemquality ruby and sapphire are being recovered, and such mining will undoubtedly continue in the future (Ward, 1991).
