Jewellery care

Our semi-precious stone pieces are hand carved and hand-picked stones, certified by a gemologist in Madrid. Kindly note semi-precious stones are extremely delicate, please be sure to handle your jewellery with care.

To ensure the longevity of your jewellery, we recommend:

Treat with care and avoid strenuous activities that could expose your jewellery to knocks and scratches.

Remove your jewellery prior to bed, as well as before showering and washing your hands.

Avoid exposing your jewellery to perfume, hair products and cosmetics.

To prevent unwanted scratches, store your jewellery separately in your Luminous 27 dust bag.

Pre Order

Bold yet refined, the Bain-de-Marie Ear Cuff is a delicate reinterpretation of our Criolla Stone Earcuffs, embodying Luminous 27’s signature balance of heritage and innovation. Shaped with the same meticulous technique as our iconic Bain-de-Marie Ring, it merges the traditional bombé silhouette with subtle pre-Columbian inspiration.

 

Each piece is 3D-scanned in our Madrid atelier, then hand-carved in Jaipur from handpicked natural gemstones and finished with an 18K gold interior and our signature gold dot. Variations in colour are to be expected and celebrated.

 

Please allow an estimated 1–3 weeks for shipment; all our fine jewellery pieces are made to order.
