Two groups of white, pearlescent and translucent bertrandite bowtie-shaped crystals assembled in the form of a wide angle V. One can still notice at the base of the V the traces of the indicolite upon which these crystals have formed, which has since disappeared by natural dissolution, leaving this intact floating group with a very symmetrical aesthetic.
