Insanely high quality rainbow fluorite (mini) slab { ‘small but mighty’ } !! Really fun + unique shape! The banding + coloration of this magnificent piece are just so clean + crisp + vibrant - it is hands-down one of the very best pieces of rainbow fluorite I’ve ever seen! Frontside + backside are both polished w:/ a silky smooth finish The clarity of this piece is so crazy!! Several naturally-occurring rainbows too!!
