Our products are produced by a couple from Maracaibo, Venezuela, who run an artisan jewellery studio in Madrid. Since 2008, we have built a long and trusting relationship with their atelier, which has become a key studio in the iconic Madrid's centre jewellery quarters.

Luminous 27 bridges old and new ways of working. We commit to exclusive, responsible and sustainable production by using traditional methods, hand-crafted techniques, and the latest technology. Producing locally and on demand allows us to support our Venezuelan community in Madrid while reducing resource and transportation waste.

Please allow est. 6-8 weeks for shipment; all our fine jewellery pieces are made to order. Please note that different prices may apply depending on the size.

Named after the gentle French cooking technique, the Bain-de-Marie Mediano Ring is the thinner version of the Bain-de-Marie Grande, our most iconic piece. This bombé-shaped solid semi-precious stone ring is hand-carved with the highest attention to detail. Embellished with an 18K gold interior coating, this elegant piece features an 18K gold drop.

Originally conceived as a single jewel, you can also stack it with other bombé rings or wear it as a pendant by adding our 90 cm or 60 cm rollo chain. All our stones are handpicked natural stones. Please be aware that colour might vary.

Please allow est. 1-3 weeks for shipment; all our fine jewellery pieces are made to order.
