The intricate carvings, reminiscent of the painting technique of cross-hatching, create a warm, woven impression on this ring. The slightly wider silhouette emphasizes its rich presence. 
The wedding rings are made using 18K gold and embody the COAS worldview.

Brass is used for hotel doorknobs and metal fittings on ships. Yui Shida creates her works using brass, a material that best expresses the atmosphere of Otaru, a city that has flourished as a trading post since ancient times. After studying sculpture at Hiroshima City University's Faculty of Arts and working as a prototype designer for accessories, she was captivated by the port city of Otaru and launched her own brand, COAS. Brass, among other metals, ages beautifully, revealing a unique character and warmth depending on the user and the environment. Using brass, gold, and silver, materials that reveal a unique character and warmth depending on the user and the environment, she creates pieces that evoke the time spent together, allowing them to be treasured for years to come. Her wedding rings are crafted from 18k gold, reflecting the COAS worldview.
