Thanks Pierre for the reply,

meanwhile I did some research on my tanakami-yama mountain, and got also info from Petrov. Seems the mountain is completely depleted by mining companies who were searching for pegmatite. According to Petrov are the crystals not in the pockets anymore,the miners had no need for the crystals and threw them away. So I should look in river beds.

Last time I was there, I saw a guy coming out of the woods with only a shovel, so I was wondering what he was digging, but he said he found a topaz of 2 cm. Now I understand he was probably digging in a river.

So I'm packing my shovel and screen, and go to the rivers now.
do crystals behave themself like gold, on the inside of curves and behind rocks? or just anywhere I can get lose dirt?

Thanks

Hi Alex, the specimens that you may find in rivers will likely be waterworn. There can be exceptions when specimens get washed out and travel a short distance downhill. If I was you, I would try to find an active/experienced rockhound in your area and ask him if you can join him on an outing. You will have to learn what to look for and that can differ from mineral to mineral and locality to locality. It is a very rewarding hobby. I jokingly say it is my opium:-)

Thanks, I know they are likely waterworn, but for my first specimens it's not so important.

The size is probably very small, so I polish them and my wife can have them for her collection.

The mountain is too famous about Topaz, so good specimens are rare there. Once I have more experience, I can look for nice terminated species. But it does not mean I can look out for good pockets while I search a river.

Saturday and Sunday 26th and 27th august 2017 (this weekend) is also a mineral festival in Nagoya, so I try to get some information over there too.
