ART NOUVEAU SILVER retailer and turquoise brooch

THIS IS A STUNNING ART NOUVEAU BROOCH WITH A LARGE TURQUOISE STONE SET IN A BEAUTIFULLY retailer CRAFTED SILVER SURROUND. I BELIEVE IT TO BE CONTINENTAL, PROBABLY FRENCH. THERE ARE NO MARKINGS, BUT THIS IS NOT UNUSUAL FOR FRENCH JEWELLERY OF THE ERA. IT IS SIMPLY STUNNING AND GIVES THE IMPRESSION OF LEAVES SURROUNDING A FRUIT OR FLOWER ON A TREE. IT IS UNUSUAL AND BEAUTIFUL ALL AT THE SAME TIME. THE C CLASP WORKS WELL ON THE BACK AND THERE IS NO DAMAGE TO THE TURQUOSIE. A STYLISH AND PRETTY BROOCH.
