Hi, currently I have a new hobby, which is collecting agate, jade and even gemstones, that is all I do because of the co-19 epidemic and requires me to stay at home.
a few days ago a friend gave me a typical Sumatran stone, especially Aceh. we call it bio solar. a few years ago Aceh was famous for producing gemstones in Indonesia, including jade and several other types.
We call the stone as "bio solar" due to the color of the stone which resembles diesel fuel, you need to know this stone is included in the type of rock idocrease. Laboratory results state that bio solar has a hardness of 7.3 mons, which means that this stone is classified as a type of precious stone.
you need to know this stone is one of the hidden natural resources of Aceh and is worth collecting.
Here are some photos af stones that have been processed by local craftsmen
if you have the same hobby as and want to have a stone like the picture above you can contact me through the comments column, you can ask about prices or even anything related to this hobby.
regards
