Seemingly delicate but strong and durable necklace from the Temps Perdu collection.
Antique Art Deco (1920s-30s) garment clip (size 21mm x 12mm) from Puces de Vanves in Paris was turned into a unique pendant. It features shimmering marcasites in four horizontal rows. Two missing marcasites have been replaced on second row from the right and second row from the left (which isn't visible in the photos) with black and clear Swarovski chaton stones, like playful winks of an eye there among the marcasites.
This necklace has a double vintage steel chain, with a beautiful labradorite gemstone drop on the other slightly longer chain. Beside the silver clasp, a creamy white mother of pearl drop dangles as an extra surprise at the back. Beads are attached with silver and gold fill findings.
Length of shorter chain is 48cm, the longer one is 8cm longer, so that the labradorite pendant hangs approx. 4cm below the vintage pendant. This creates a modern, layered look from almost entirely vintage and antique materials.
The vintage pendant is made of possibly silver plated metal, perhaps brass or some other alloy. But it's almost a hundred years old so it's impossible to know for certain. If you have sensitive skin, it would be safest to wear the pendant on top of clothing, but the choice is yours. The chain is steel and clasp is sterling silver so those parts pose no risk of skin irritation.
