Well this one's been in my possession for a very long time - I picked up this one at the Tuscon Gem show late 80's. These specimen glass containers are no longer made in glass to the best of my research. The optical quality is exceptional. The lid detaches completely. The piece of amber in this one comes from my friend in Poland. It does contain a small bug within the amber. Once the chinese started making fake amber I quit purchasing all amber so my supply is limited to what I have on hand. The container measures 1 1/4" tall and wide. Very nice display item.
