I think the best course of action would be to just get some razor blades/box cutters and some guitar wire and start cutting all of the seams apart so that you just have all of the glass pieces separated. Then use the base as a template to build or have built a new base and replace it completely. Clean all of the glass with acetone and be sure to keep track of which piece goes where. Once all of that is done and the base is waterproofed, you can begin reassembling everything with new silicone. It is a lot of work but it's far from hopeless.
If you're truly no longer interested then I would recommend looking for a buyer that is willing to give you what you paid for it, or just cut your losses and give it away.
