Ema Eggs, also known as Seer Stones or Window Quartz, are pieces of quartz found primarily in the Ema River in Brazil. Their unique formation is a result of naturally tumbling through the river. Each stone has one face cut and polished smooth, allowing one to see the natural crystalline structure within.

The "window" of the stone is believed to help one look deeply into their own spiritual state. Like a crystal ball, gazing into the window can quiet the mind to receive intuitive insights or visions. 

The stone(s) received may slightly differ in size/shape/color than those photographed.
