Vintage Coro Sterling Bouquet Brooch

For your consideration, a stunning statement  brooch pin signed Coro Sterling, based on my research could be by Adolph Katz, vintage 40s-50s, featuring a flower/ shamrock/ three leaf clover bouquet made out of sterling silver, with rich rose gold wash finish over sterling, accented with faceted emerald glass stones, beautiful in its simplicity, a rare and collectible jewelry piece from a Montreal estate! Condition: pre-owned vintage condition, the mechanism works great, some expected signs of wear/aging as seen in the close up photos consistent with normal use, vermeil is in great condition for the age. Measurements: 7 x 4.2 cm Please view the photos for measurements and details
