Oodles of gemstones incorporated into this..... turquoise, mother of pearl, hemimorphite olivary, cultured pearls, amethyst, agate, gold coral, blue sand night stars sitara, lapis lazuli plus dichroic cabochons. Measures 45 x 25 cm (18 x 10") I can't describe how easy and fulfilling this was to do! My life has been crazy lately, whether this mosaic depicts that? All I know is that it kept me sane while everything else wasn't!
