Here is a glorious Art Deco brooch with a large chrysoprase oval stone and an elaborate sunflower pattern done in tiny, dazzling marcasites. The horizontal central stone appears to have expanding ripples of sterling bands, held by bars of marcasites. Four gorgeous half-sunflowers anchor the four scalloped corners. My pictures don't do justice to the sparkle and heft of this large pin. Exceptionally beautiful! It measures 2-1/4" by 1-5/8 and is marked Sterling, 154, M M. It is missing three stones and two stones are chipped. I set about fixing them, but they were so small I wasn't able to find substitutes. Fact is, you don't notice the individual stones.
