Laguna Agate slab from Ojo de Laguna, Chihuahua, Mexico. Very colorful and unusual double oval agate formation - one oval side has pronounced red/white fortification banding, translucent, and a center edged in clear druzy. The other oval side is translucent and filled with sagenite, moss and tubes in brown on clear agate. Best of both worlds! Front face of both is highly polished.
