18kt Yellow Gold Ring with citrines

Our designs have a quality certificate from the firm with the technical characteristics of the materials used during the creation process.

All our jewels are handcrafted in Spain by our team of master craftsmen using techniques of ancient tradition. The diamonds, precious stones and pearls that we use go through a rigorous selection process in order to opt for the best quality materials, one of the pillars of Eugenio Lumbreras.

All diamonds we work with are subject to the Kimberley KPCS convention (certification system for international trade in non-conflict diamonds). From half a carat they have certificates from the best international laboratories: GIA, HRD or IGI.

The fine stones have been extracted ethically and responsibly, following the guidelines of international agreements, and are meticulously set one by one.

“Every Eugenio Lumbreras jewel expresses the quality of a unique and 100% handmade creation process, which strives to achieve perfection with each of its details.”.
