Seed 117 necklace begins with BOULO's signature form, held only at its upper half where it meets smoky quartz. From there, the line extends, drawn into volume and transforming the piece into three-dimensional form. The closure sits at a precise 45-degree angle and is set with 117 diamonds, adding light as a subtle discovery without interruption. On the reverse BOULO's monogram appears for the first time, carved as negative space blocks - subtle, recessed, and intentional, present by absence. Designed to be felt from every angle, Seed 117 necklace continues where most jewellery pieces end.
Designed in London, crafted in Istanbul.
