A Rare Octagon (or Emerald) Cut Blue Sapphire Diamond Engagement Ring

This design is inspired by our client and was custom-made by our CAD designer.

This particular engagement ring was custom made with a certified 1.13-carat Royal Blue Sapphire center, supported with two emerald cut 0.32-carat diamonds, and 18K White Gold.

The blue sapphire was 100% eye clean and has been certified as ‘Heated.’

This means the stone has been subject to normal heat treatment which is normal with 99% of all blue sapphires in the market.   Also, there is no advanced treatment like beryllium or lead glass-filled which is a lot cheaper.
