Celestial Geometry: A Sapphire and Diamond Ring by JANA

A jewel composed like a constellation.

This extraordinary 18k white gold ring by JANA draws the eye inward, toward a 2.11-carat sapphire of mesmerizing depth—midnight blue, steady as a planet in its orbit. The central gem is encircled by a radiating double halo of baguette and brilliant-cut diamonds, their icy shimmer creating a luminous corona that recalls both Art Deco precision and cosmic mystery.

Framing the gallery, pavé-set sapphires swirl along the shank, adding dimension and tonal intrigue to the design. Sculptural, symmetrical, and unflinchingly opulent, this is a ring that holds its own gravity.

A planetary halo for a woman who orbits no one.
