18k Art Deco Multi-Colored Gemstone Station NecklaceA full rainbow spectrum in a single, long chain. French, Art Deco, 18k yellow gold. This lovely necklace is a continuous run of bezel set gemstones semi precious, glass and synthetic. Worn long, it reads as a quietly maximalist statement. Doubled, it becomes something else entirely. The gemstones are glass (green stones), semi precious (amethyst, citrine, garnet, sapphire) and synthetic (spinel). Yes, that's a very mixed bag but 100% period
