A bold interpretation of BOULO’s signature design, this ring features a hand-carved Aventurine as its focal point. Subtly framed by delicate stones, the composition enhances the depth and smooth texture of the carved surface without overpowering it. Designed for those drawn to sculptural rings, Shapeless stone offers volume with everyday comfort. The result is a distinctive piece of colourful fine jewellery - rooted in craftsmanship, rich in character, and defined by an effortless sense of individuality.
Designed in London, crafted in Istanbul.
