Agate from Mexico, Chihuahua, Estacion Ojo Laguna

Nice little agate with lilac, orange and red banding. The seller told me that this was from the "Alianza" claim and was older material, but I have seen some from Coyamito that are similar, so am unsure if the locality is correct. It is definitely from the Laguna area, Chihuahua Mexico. This piece didn't have the best polish and had some light scratches, and I traded this out to another collector several years back and I regret it as its so hard to find good ones with this color sequence. Ex Christopher Wentzell collection. about 1.75 inches across.
