Nature, you have outdone yourself.
This is a piece of dendritic agate from Brazil. I met a lovely family at Tuscon that comes up every year and the papa, Mani, is who cuts this. Dendrites form when iron, iron oxides, or manganese grows along the quartz matrix. I think it is one of the most fascinating and beautiful things I have ever seen.
This stone is for growing to trust our quite intuition.
Dendritic quartz + sterling. 16-18 inches, adjustable
