This important and fancy ring was handcrafted in brushed 18kt yellow gold with diamonds. It was designed in Art Deco style and Fibonacci measures, giving harmonious proportions to the jewel. This accessory comes from Brazilian jewellery designer Yrys Albuquerque, and her eponymous brand YRYS. The brand is known for consistently adhering to the strictest quality standards – Yrys works with expert Portuguese artisans, and sources her diamonds from reputable New York sources. Five percent of all YRYS sales are donated to schools attended by young children from the favelas of Rio de Janeiro.
