Dating from the early 1980s, this Tiffany & Co. "Pansy" brooch by Angela Cummings is composed of opal, malachite, mother-of-pearl, and 18K gold. It is designed as two contrasting pansy blossoms, alternately set with black opal and mother-of-pearl petals centering black jade accents, supported on stems with a malachite leaf. Crafted by extraordinary lapidaries, this charming abstract flower formed of gems with vivid, iridescent phenomena is easy to recognize as a classic Cummings design for Tiffany & Co.
