About this Product
I made this bottle specifically because I have some loose stones (y'know, like crystals or other gems) and I wanted to wear them safely around my neck without fear of losing them. I didn't want to wear or wrap them in a typical way so I figured to capitalize on the success of my Message In A Bottle idea - viewable here: http://shpws.me/oFLj and do something a bit more dramatic... the screw top fits into the bottom filigreed area which is hollow and should fit stones with less than a 2 cm width (as I designed it, but I have to print it out to double check) - some areas are carved out, some have material behind them to keep the design legit so you don't see a complete cutout of the filigree, but it should be enough that you can look in and see the stones, especially when you hold it up to light. BTW: the price is mostly the cost of material - I'd have loved to make it more reasonably priced.
