Open-arched filigree and milgrain trim highlight the 18k white gold band of this vintage style blue sapphire engagement ring. A collection of twenty princess and round brilliant cut diamonds cascade down the shoulders and accentuate the shank. The combined weight of all the diamonds is 0.50 carats. An round blue sapphire ascends from the center of this diamond shimmer. This is a new filigree and sapphire engagement ring.
