Acrylic cube. Gadolinium (Gd). 25 mm.

Who came up with the idea of ​​creating chemical elements in acrylic cubes ?! This is not our idea, unlike key rings and pendants, but the creator's name is Juergen, and he lives in Austria. When I saw his cubes, I thought that this is just a great way to collect items, which has many advantages. At least the elements do not oxidize, they retain their original shine, and ampoules with cesium and bromine, for example, cannot be broken inside a cube! But in our market no one offered such cubes, and we also have a lot of collectors ... Why should they be deprived of such an opportunity as collecting elements in acrylic ?! Therefore, we also decided to make them!
