Cool and composed, the Atelier Petits Ring with sapphire brings clarity seeps into BOULO’s fluid aesthetic. The sapphire is set directly into the sculpted gold form, creating a calm focal point that feels integrated. Smooth contours and softened edges allow the ring to sit comfortably, while the deep navy Sapphire stone adds a sense of quiet depth. Designed to move effortlessly between day and evening, this ring reflects BOULO’s fresh take on its signature approach to form.
Designed in London, crafted in Istanbul.
