Geodes (Greek geoides, "earthlike") are geological rock formations which occur in sedimentary and certain volcanic rocks. Geodes are essentially rock cavities or vugs with internal crystal formations or concentric banding. per Wikipedia.
However, given the plethora of said items, it didn't surprise me in the least to see geodes and other mineral sculptures popping up everywhere as a new variation on Earthen elements in design.
Sometimes they aren't very conspicuous, like say, that mammoth set of moose antlers one Domino room featured, but they are elegant, light-catching and ethereal. Some people believe the gemstone crystals bestow health and well-being - something I certainly won't turn down!
See if you can spy the little pretties in these rooms - remember, they are sometimes very discreet - how classy of them!
So, keep your eyes peeled....the next "it" thing in design might be right under your proverbial nose!
