Vintage 925 Sterling Silver Art Nouveau Naturalistic Pendant, Natural Malachite

Very unique vintage / antique Art Nouveau pendant. Handmade. Naturalist / Brutalist style. With natural green malachite stone, cat eye shaped. Not stamped, but was professionally tested as 925 sterling silver. Heavy, close to 12 grams in weight. 2" long (with bail). The stone has some fading of the original surface shine, as pictured, which can happen with age. It can be improved by rubbing a tiny bit of coconut oil.
