Very beautiful antique festoon necklace! it is Arts Crafts to Art Nouveau period. Crafted in solid sterling silver. In excellent condition and clasp works well! Very well built! Hallmarked sterling- please see photo. Has 5 big fiery opals paste. Please see photos as part of description. it is 39cm from end to end. last photo shows how it looks next to skin. as with any opal - the best flashes are under bright light; from one side it can be more flashes and from another less. no damages/no cracks/no crazing to the cabochons. very translucent opals - see photo next to a window. the cabochons are domed not thin but raised - very pretty! my apologies, I can not review offers on this item. fast shipping! smoke free environment! thank you!
