i've been on a big crystal/quartz kick lately, and the top three are just the most recent acquisitions. i love the intrinsic quality of these (essentially) glorified pieces of rock that make each chunk entirely unique - no two shapes are the same, no two markings are the same, no two pieces reflect light in exactly the same way - it makes each one so uniquely beautiful, in its own right.
i'm not a huge believer in the whole power of 'healing crystals' thing, but i do like to think that if looking at these little treasures each time brings even the slightest moments of happiness, of peace and of joy, that's healing power enough for me.
