A rare and exquisite vintage designer necklace with a heavenly influence of Art Nouveau, created by Oscar de la Renta. This sculptural piece captures the poetry of the sea with masterful balance: golden textured shells and starfish seem to float alongside vibrant glass crystals in rich tones of emerald, ruby, topaz, and peridot. The design is theatrical yet refined, rooted in nature but elevated into wearable art — a hallmark of Oscar de la Renta’s most iconic costume jewellery. It is both romantic and powerful, with a distinct marine fantasy flair, evoking the elegance of turn-of-the-century decorative arts.
