I'm drooling over these unique terrariums found on Score and Solder. What an amazing display for a console table or even on your dining table! I can imagine them even as wedding centerpieces. The prices are a little high if you think you'll tire of them soon, but if you love them, it's an investment, right? wink, wink
In a similar vein (but without the gem-inspired faceting) you can get the soldered glass look for less at Crate and Barrel (for a more traditional terrarium styling) and at West Elm (for a higher glass-to-seam ratio).
