Soft yet expressive, the Atelier Petits Ring with pink sapphire explores BOULO’s amorphous design through fluid gold and a vivid stone. The sapphire appears gently embedded within the surface with bezel setting, as if naturally formed rather than set, allowing colour to emerge with quiet confidence. The silhouette wraps the finger comfortably, creating a sense of movement and ease. Playful in tone, tactile in feel, this ring brings a subtle warmth to everyday wear.
Designed in London, crafted in Istanbul.
