IGI Certified 3 Carat Marquise Cut Lab Grown Diamond Split Shank Engagement Ring

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.

Round lab grown diamond accents add brilliance across the divided band and bridge, giving the ring a detailed, dimensional look while preserving the marquise diamond as the unmistakable focal point.

It features brilliant-cut faceting, E color, VS1 clarity, and a prong setting, with IGI certification supporting its grading details. Sixty round lab grown diamonds add approximately 0.42 carat across the split-shank design, bringing the ring to an approximate total stone weight of 3.42 carats. The accent diamonds are E-F color, VS quality, brilliant cut, and prong set. The confirmed version is crafted in 92.5 sterling silver with an approximate metal weight of 2.96 grams. What Makes This Marquise Diamond Split Shank Ring Special Approximately 3.00 carat IGI-certified marquise lab grown diamond as the center stone. Elongated 15 x 7 mm center diamond with E color and VS1 clarity. Brilliant-cut faceting and a prong setting emphasize the marquise silhouette. Sixty round lab grown diamond accents total approximately 0.42 carat. E-F color and VS quality side diamonds add bright contrast around the center. Split-shank construction creates an open, dimensional frame leading toward the marquise diamond. Additional diamond detailing along the bridge adds sparkle beyond the top view. Approximately 3.42 carats of total diamond weight. Why Choose a Vintage Inspired Marquise Diamond Engagement Ring The marquise shape combines an elongated outline with pointed ends, creating a dramatic center profile that naturally draws attention along the finger. Here, the split shank expands toward the center and surrounds it with round diamond sparkle, while the diamond-set bridge adds detail from the side. The result blends vintage-inspired character with a more dimensional engagement-ring silhouette, making it especially fitting for someone who wants a proposal ring that feels expressive, distinctive, and centered on one commanding diamond. IGI Certified Lab Grown Diamond Craftsmanship & Authenticity The 3 carat marquise lab grown diamond comes with an IGI Certificate, providing independent grading documentation for the center stone. Rosec Jewels also offers certification of authenticity with its jewelry for added product confidence. The ring is crafted with attention to secure prong settings, split-shank alignment, bridge detailing, and refined finishing, with stone inspection, setting security review, and finishing inspection completed before dispatch. Care guidance further supports responsible long-term wear. Styling a 3 Carat Marquise Lab Grown Diamond Engagement Ring The elongated 15 x 7 mm center diamond creates strong finger coverage from above, while the split shank and diamond-set bridge add visual interest from multiple angles. Its substantial center makes it especially suited to a statement proposal or milestone anniversary, while the vintage-inspired detailing gives it more personality than a plain solitaire. The sterling silver setting provides a cool-toned backdrop for the E-color center and bright E-F accent diamonds, allowing the diamond arrangement to remain the focus.
