Check the listing for details. Hand Painted Rock / Stone - Mandala Zentangle silver black gray. Condition: New. Listed at 18.50 USD. This one-of-a-kind Zendoodle stone is hand-painted using silver oil-based paint over a 100% natural black river rock sourced from a northwest Oregon creek. The stone and paint are sealed with a clear spray coat to keep it safe from minor wear over time. The stone is about 3" at its widest point -- just the perfect size for holding in your hand or for display in a plant pot, on a desk, or on a windowsill. Makes a lovely gift of appreciation, especially for the art and nature lover in your life. Influences for the design come from Henna, Zentangle, Zen doodle, nature, botanical, floral, and abstract art ----- A portion of all my sales goes to St. Jude Children's Research Hospital in gratitude. I would not be here today without research going towards curing childhood leukemia through cord blood transplants.
