In 2026, a new team is breathing new life into the brand and continues to create unique jewelry in gold, vermeil, and silver, handcrafted by master jewelers in France.

It's normal for jewelry to lose its luster, and this depends on the type of metal. Here's what you need to know based on your piece of jewelry:
Silver – Silver naturally tarnishes when exposed to air and sweat. This is unavoidable, but reversible: regular polishing with a soft, silver-specific cloth is enough to restore its shine. Avoid seawater, swimming pools, and household cleaning products, which accelerate the tarnishing process.
Vermeil – Vermeil is silver plated with 18-karat gold and finished with 24-karat gold. Avoid contact with cosmetics, perfumes, and chemicals. Re-gilding restores the original luster—we recommend doing this as soon as you notice the gold plating beginning to wear.
Yellow Gold, Rose Gold – Gold does not oxidize, but it can become slightly dull due to buildup from cosmetics, creams, or soap. Washing it in warm, soapy water and drying it gently is usually enough to restore its original luster.
White gold — White gold is rhodium-plated, which gives it its brilliant, intense white appearance. This rhodium plating wears off over time—this is completely normal. Re-rhodium plating restores the original luster—we recommend doing this as soon as you notice even a slight change in color.
In any case, there are certain steps you can take to keep any metal looking shiny: remove your jewelry before exercising, swimming, using household cleaning products, or applying cosmetics. Store your jewelry separately in a soft pouch to prevent scratches.
We offer a comprehensive maintenance service to restore your jewelry to its full luster:
- Yellow gold: polishing
- White gold: rhodium plating
- Silver: polishing
- Vermeil: re-plating – 45 € (return shipping included)
