Custom Design

The Brazil Paraiba Tourmaline Halo Diamond Ring was built around a stone that does something most gemstones don’t — it glows from within. This 0.4ct Brazil Paraiba, GIA certified with confirmed Brazilian origin, carries a neon blue-green saturation caused by copper within the crystal. At this weight it holds its own against the surrounding diamond halo without effort.

The round brilliant halo reads as a single floral cluster at a glance, with marquise diamonds continuing along the band in a vintage rhythm that gives the piece its period character. White gold was the only practical metal choice — anything warmer would pull the Paraiba toward green and compromise the neon quality that makes the stone worth commissioning around.

Commission Showcase

This Brazil Paraiba Tourmaline ring was created exclusively for a GIOIA client and is not available for purchase. Every piece we make is a one-of-a-kind commission built around a specific stone and a specific brief. If this design speaks to you, we can create something in the same spirit — with a Paraiba tourmaline sourced and assessed by Clarence.
