Azure Sapphire Halo Ring

Sapphire sits at 9 on the Mohs scale, second only to diamond, which is why it has been a working engagement stone for two centuries rather than a novelty. The colour here is a mid-royal blue, saturated but not so dark that it closes up under indoor light.

The diamond halo on Azure is set slightly below the crown of the sapphire rather than level with it, which keeps the eye on the colour instead of letting the white stones compete with it.
