Size: Large Oval. This particular piece of Texas Turquoise (Polychrome Jasper) from Brewster Co., TX is super unique in the picture that it reveals inside of itself. A gaggle of ducks can be seen flying away from the surface of reeds in a mossy pond or lake. Picasso Stone art principles inside of a piece of Texas Turquoise—truly unique this piece is. Earth and water and the harmony of life within it can all be found in this one of a kind piece.
