Love the mounted geode! Or you could DIY mount the Swirled Geode Knob in pinks or beiges from Anthropologie http://anthrpl.ge/1n566fw and mount it in the deep white Ribba frame from Ikea http://bit.ly/1lYDUs3 without the glass. (Spray it silver if you prefer). Geode-$18.00 Frame-$9.99 Silver spray paint-$6-$8!
I think the "cheap" version is almost way cleaner then the expensive version. Its a lot more simpler and the Geode looks a lot more real!
