This Shapeless Stone ring centres on a hand-carved Smoky Quartz, bringing warmth and depth to BOULO’s signature form. An unseen internal structure holds the composition together, allowing the form to remain fluid and effortless. Framed subtly with small stones, the design highlights the natural tones of the quartz while maintaining a refined balance. Slightly bolder in presence, it works beautifully as a cocktail ring - confident and composed. A modern fine jewellery piece that blends sculptural design with earthy elegance, created for those who appreciate distinctive materials and thoughtful craftsmanship.
Designed in London, crafted in Istanbul.
