Thanks Don,
Although I have quite a few, I don't usually post my silver specimens as they are primarily Canadian and can be a bit boring. My collection is quite small so there isn't much opportunity for new additions. The Gold specimen is particularly special to me as it is from my home country.

Thank you very much Don, I've finally returned home after a long stay in Tucson. I managed to pick up a few new pieces and will add them as time permits.

Hi Joseph,
congratulations on the new specimens! That vivianite is a stunner, a true museum piece! I must confess that vivianite was never a mineral that attracted me until I saw these pieces from Brazil. I would even consider to add one to my collection ;-)
A great piece, the ludlamite too; I can't wait to see the other new additions!
Regards
Tobi

Thank you Tobi, I usually spend a month on my treasure hunt at the Tucson show as many dealers open early, it affords me the time to find some of the more unusual things.
