FAQ
THE COMPANY
Thea Jewelry is a bespoke jewellery brand founded in 2011. In 2026, a new team is breathing new life into the brand and continuing to create unique pieces in gold, vermeil and silver, handcrafted by jewellery artisans in France. Pieces designed to reflect who you are, tell your story and be with you every day.
Our jewellery is handcrafted in partner workshops in France, selected for their expertise, ethical standards and responsible practices. It is made from recycled precious metals.
Each piece of jewellery bears the state hallmark and the maker’s mark of the workshop where it was crafted, certifying the quality and authenticity of the precious metals used. You will also find the name ‘Thea’ engraved on the inside – the brand’s discreet signature.
Thea Jewelry is an online-only brand.
However, we do occasionally hold pop-up events where you can come and discover Thea jewellery. Follow us on Instagram so you don’t miss a thing @theajewelry.

It is normal for jewellery to lose its shine, and this depends on the type of metal. Here’s what you need to know depending on your piece of jewellery:
Silver – Silver tarnishes naturally when it comes into contact with air and sweat. This is inevitable, but reversible: regular polishing with a soft, silver-specific cloth is enough to restore its shine. Avoid the sea, swimming pools and household cleaning products, as these accelerate the process.
Vermeil – Vermeil is silver plated with 18-carat gold and finished with 24-carat gold. Avoid contact with make-up, perfumes and chemicals. Re-gilding restores the original lustre – we recommend this as soon as you notice the gilding starting to wear off.
Yellow gold, rose gold – Gold does not oxidise, but it may become slightly tarnished due to build-up from make-up, creams or soap. Washing it in lukewarm soapy water and drying it gently is usually enough to restore its original shine.
White gold — White gold is rhodium-plated, which gives it its brilliant, intensely white appearance. This rhodium plating wears off over time: this is perfectly normal. Re-rhodium plating restores the original lustre – we recommend this as soon as you notice even a slight change in colour.
In any case, there are certain things you can do to keep any metal looking shiny: take off your jewellery before exercising, swimming, using household cleaning products or applying make-up. Store your jewellery separately in a soft pouch to prevent scratches.
We offer a comprehensive maintenance service to restore your jewellery to its former splendour:
- Yellow gold: polishing

- Vermeil: re-plating – €45 (return postage included)
