Not all Basalt is created equal - there's polished material - and of course the famous natural formations of it (I think Devil's Tower may be made of it). Anyhow, my personal favorite is the Ventifact - a name that comes from Latin, "Venti" being wind - and "Fact" meaning "made" (think "fait" or made, in French). Indeed these shards of igneous (magma or volcanic) rock - found near the South Pole, on the open steppes of Argentina - are shaped by wind and sand (or airborne particles).
All of mine seem to be 3-sided, which is kind of unique in the stone world, and has meaning for those who believe in the Trinity of any sort (not just Christian). There is a 3-sided dagger of Spiritual significance in Tibet. And then of course, there is the pyramid, trigon, or Crystalline "record keeper."
Ventifacts - as a result of having been polished by nature, comparable to river worn Jades - have a magnificent, soft and smooth surface.
They are like a wand, but not a conduit for our energy. They are what I call "the black torch" - clearing (and oddly, lighting) the way before us - like Ganesha, the Indian elephant deity (who is associated with successful ventures).
I always recommend Ventifacts for people looking for support in their movement and progress. Small pieces impart the energy directly to the hand, and are easier to store, and have around. The bigger pieces can "hold" a room, or be part of larger layouts or (as I call them) "constellations."
One of my favorites, for sure.
