Rainbow Lattice Sunstone 3.72 ct

Specimen of the extremely rare “Rainbow Lattice sunstone” with a polished crystal face.

It is a natural stone, without any treatment.

The amazing rainbow effect is only visible when light hits it at certain angles.

It comes from the Rainbow Serpent mine, in the Harts Range, northeast of Alice Springs, Northern Territory, Australia.

A very interesting material for a high level collector.
