Oya stone is known for its uniquely beautiful texture. In the past, Oya stone was used without a second thought for daily life settings like stone walls. But recently it has captured attention for its use in fashionable interiors. The greatest allure of Oya stone is its varicolored and uneven surface. These features create its distinctively "warm" surface. Utilized for this texture, which other rocks do not have, Oya stone has been used in a variety of famous architectural showcases, and we will see how and why in this program.
