This is a Turkish agate. It is an unusual piece as it contains a combination of waterlines, banding and tubes.
The outside is a reddish-brown with banding ranging from light bluish-gray to white with clear and translucent agate throughout.
There is slight pitting where the tube formations touch the surface. This is a natural portion of the tube formation makeup.
When the quartz appears in transparent and opaque shades, many regard it as a marker for feng shui that helps boost the flow of energy in a living place. Agates carry a quiet energy that works on the subtle bodies, and are great for achieving stability and balance in many aspects of one’s life.
