A vibrant oval lab-created turquoise at the center of a signet ring face, framed by a CZ halo in 14K gold over sterling silver - the turquoise providing the opaque, vivid color and the CZ halo providing the sparkle perimeter that amplifies the stone's presence. The signet format gives the turquoise a contemporary architectural context that a conventional bezel solitaire would not - the flat, oriented face of the signet is the right stage for a color stone that deserves to be read rather than simply seen. Lab-created turquoise ensures consistent color across the stone's surface. A color ring with genuine design intelligence.
