Between Blue and Green

Some stones invite a second look.

At the heart of this ring is a 13.13 ct cushion-cut tourmaline. Its colour moves between blue and green as the light and viewing angle change, revealing different facets of the same stone.

A fine diamond halo follows the cushion’s softly rounded outline. Further diamonds continue along the shoulders, while the white gold setting keeps the palette cool and clear.

A substantial stone, framed with a light touch.

Before the Gold

The stone comes first. Then we explore what surrounds it.

This 3D design study shows how the setting takes shape around a cushion-cut tourmaline. Proportions, the diamond halo and the profile of the band can be considered from every angle before work begins in gold.
