Inspired by the intricate architecture of sea urchins, this 18K yellow gold solitaire necklace showcases an inverted-set blue sapphire, capturing the delicate beauty and structural elegance of its spindles. The inverted gemstone adds movement, depth, and a subtle architectural edge, paying homage to the natural world while introducing a modern twist.

Suspended from an 18" adjustable slider cable chain, the necklace can be worn at any length up to 18", allowing for versatile layering or solo wear. A flirty, curated statement piece, this necklace celebrates classic elegance with a hint of punk-rock energy.
