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.

Product Details Win her heart by presenting this stunning Heart Pendant Necklace, a piece that speaks the language of elegance and romance. At the center shines a 4 mm Heart Shaped Black Onyx set in Prong Setting, rich and mysterious, beautifully framed by a sparkling Diamond Halo that catches the light from every angle. Just below the bail, three graceful Diamond stones dangle softly, adding extra shimmer and movement with every step she takes. The contrast between the deep AAA Quality Black Onyx and the HI-SI Quality Diamond stones creates a bold yet timeless look that feels both modern and classic. Designed with a secure Lobster Clasp Closure, this Black Onyx Diamond Necklace offers comfort and confidence for everyday wear or special evenings out.
