Description
This magical blue sapphire ring was designed for our clients from Renton, WA. The couple started with inspirational photos while visiting us at our flagship store in Bellevue, WA. Our designers helped them picture the ring of their dreams through quick sketches, followed by renders for a more realistic feel. Once our clients were satisfied with the final outcome, a wax model was printed for them to view, and then moved into production.

Three Stone Style
This striking blue engagement ring features a 1.44 ctw elongated cushion cut sapphire. It’s hugged by two half-moon diamonds and all held in place by a shared prong setting.
The side stones showcased in this ring flawlessly line the straight edge of the cushion cut sapphire. The other side of the half moon, is curved in shape, and brings contrast to the overall look.
It is known that an engagement’s ring sparkle is enhanced with a three stone style. The side stones always contribute to an extra level of flare. If you or your partner is fan of extra sparkle then you can never go wrong with a three stone engagement ring. It’s typically a timeless design that never went out of style.
The approach to designing this ring was simple yet very classy. The choice of pairing the half-moons with the cushion cut was a winner and uplifted the whole design.
Customization
For a more modern look, try this design in rose gold. Or if you are a vintage fan then we recommend this beautiful ring in white gold with a hand engraved band and filigree on the shank shoulders for more intricate details.
