0.4 Carat Round Shape Black Onyx Vintage Engagement Ring with Diamond Halo

The Sapphire Reverie • A Legend in Ceylon Blue

Hand-crafted by master jewelers in our private Manhattan salon, this creation marries the hypnotic depth of rare Ceylon royal blue sapphires with the fire of triple brilliant-cut diamonds. Each sapphire is custom cut to maximize light refraction through its 57 precise facets, emitting a vibrant azure glow in any lighting condition.

Flanking the oval centerpiece are six carefully matched F-color diamonds arranged in graceful trios, reminiscent of blossoming lotus leaves. The ergonomic band is hand-beveled to guarantee supreme comfort for everyday wear.
