This piece will blow your mind. I have never seen a more beautiful specimen. It is 7"x 6"x 10.5" when standing alone. It looks beautiful lit by one of our black mica bases. It really sets it off with the gooseneck light shining on its many colors, then to have it rotating so you can see all of its beautiful sides, you won't be able to take your eyes off of it. You must add 5 more inches for the base, which measures 9.5" x 9.5" x 5". The calcite alone weighs 19.75 lbs.
