The history of Hilutit
Our longtime friend and gemstone supplier from Sri Lanka told us in 2004 about a new discovery. He had discovered by chance in the deepest jungle, and was immediately fascinated by its many facets.
Since he was not aware of the stone , he tried it in Sri Lanka to examination by gemologists . Unfortunately, there was one study to nothing and so he asked us to him in Germany and decide to leave .
In Germany too, the stone could not be classified first . After several unsuccessful tests in various institutions we turned to the University of Mainz and gave again the provision in order.
There it was found out that it is a garnet - zircon - goethite - quartz Composition and the stone is in this form is unique.
Mining / transport
The Hilutit comes from a rugged region in the deepest jungles of Sri Lanka. The mining and transport are considerable difficulties , as there are no paved roads in the area . The stones have to be worn over narrow paths with muscle use patterns, with large trees , bushes, valleys and mountains natural barriers. Then they are transported with tractors a few miles to the truck, which they then bring to finishing.
Processing
Currently, the Hilutit is only processed in Germany because Sri Lanka lacks the necessary know-how and the machines are not available.
With the recent conclusion of the war it is now finally possible to build social projects in Sri Lanka.
As a founding member of the "Fair Trade Gems & Minerals Association" (www.fairtrademinerals.de) our long-term goal is processing the Hilutit in Sri Lanka.
