Important sculptural bowl carved by hand from a solid block of orange onyx. Each bowl is hand-signed and numbered by the artists (engraved). 100% handmade in Italy comes with a "Certificate of Authenticity". Onyx is a natural material, every piece is unique as each onyx block is different in veins and color shades. All of our creations are handmade by Italian artisans and can slightly vary in shape and size.
