This platinum diamond engagement ring features a 1-carat emerald cut center diamond framed by a luxurious double halo of round brilliant accent diamonds. The split shank band is set with pave round diamonds along each strand, adding brilliance and depth from every angle.
The total diamond weight is 1.50 carats, with diamonds graded VS2 clarity and I color โ a combination that offers excellent transparency and near-colorless appearance to the eye. The emerald cut center stone showcases the clean step-cut facets characteristic of this classic shape, making inclusions easier to assess while delivering a refined, elegant look. The double halo dramatically frames the center stone and creates the impression of a larger total face-up size.
Crafted in platinum, the setting provides a naturally white, durable, and hypoallergenic metal that will not fade or require replating over time. The split shank design adds architectural elegance and allows the ring to complement a variety of wedding band styles.
