Amazing ( if not phantasmagorical!) are just a couple adjectives that come to mind when describing this precious masterpiece from early-20th century France.
Art Nouveau
artistry is in full flower in this stunning and sizable (2 and 3/4 by 2 inches) jewel, composed of black opals, white opals, diamonds and demantoid garnets. The colorful blossom of organically shaped gemstones, centered with a light 2.00 carat diamond stamen, is further enhanced with clusters and constellations of sparkling diamonds set in platinum bezels. The diamonds and opals are wreathed in graceful branches of demantoid garnets composed of contrasting yellow gold. An utterly sensational, and uniquely beautiful, wearable work of jewelry art. As would be expected, the opals show some crazing.
