Lab Grown 4 Carat Diamond Princess Cut Engagement Ring with IGI Certificate

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.

Its square center diamond delivers a strong, defined presence, while round diamond detailing along the collar and a surprise diamond introduce sparkle from more than one angle. A bold shank completes the contemporary silhouette, creating a proposal ring for someone drawn to statement proportions, crisp geometry, and meaningful detail. 4 Carat Princess Cut Lab Grown Diamond Engagement Ring Details The design places an IGI-certified princess cut lab grown diamond at the center of a solitaire-led setting, balancing substantial scale with carefully placed accent sparkle. Its raised peg-head presentation keeps the square center stone visually dominant, while the collar diamonds and hidden surprise detail add interest beyond the face-up view. Center Diamond: Approx. 4.00 carat princess cut lab grown diamond, measuring approx. 8.50 x 8.50 mm Center Stone Quality: E color, VS1 clarity and brilliant cut Center Setting: Peg-head setting Accent Diamonds: 28 round brilliant lab grown diamonds totaling approx. 0.13 carat Accent Quality: E-F color and VS clarity Accent Sizes: 26 diamonds at approx. 0.90 x 0.90 mm and 2 diamonds at approx. 1.50 x 1.50 mm Metal: 92.5 sterling silver and selected yellow or white gold options in 10K, 14K, and 18K Ring Dimensions: Approx. 8 mm wide and 9 mm high Metal Weight: Approx. 3.52 gm Princess Cut Diamond Design for a Bold Engagement Statement Ring The princess cut is a natural choice for someone who prefers defined lines over softer silhouettes. Its square outline gives the center diamond a confident focal presence, while brilliant faceting brings light and movement within that structured shape. Here, the bold shank supports the scale of the center stone and the smaller round diamonds add contrast without competing with it. The surprise diamond offers a more intimate detail, making the ring especially fitting for an engagement, anniversary, or milestone that represents both a public promise and a personal connection. IGI-Certified Lab Grown Diamond Ring Craftsmanship & Authenticity The E color, VS1 clarity center lab grown diamond is accompanied by IGI certification for its graded characteristics, while Rosec Jewels offers a Certificate of Authenticity with the jewelry for added product confidence. The ring is carefully crafted with attention to stone placement, setting security, and refined finishing. Before dispatch, each piece goes through stone inspection, a setting security review, and a finishing inspection. Care guidance is also part of the customer support experience, helping you protect the diamonds, sterling silver, and setting through appropriate cleaning and storage. Princess Cut Engagement Ring Style & Wearability Viewed from above, the 4 carat princess cut diamond creates a strong square centerpiece; from the side, the raised profile reveals the collar accents and surprise diamond that give the design added dimension. The bright tone of 92.5 sterling silver keeps the overall palette crisp and easy to coordinate with other white-metal jewelry. Its substantial center stone and approximately 9 mm height make it particularly suited to proposal moments and occasion styling, while regular wear is possible with mindful care. Removing the ring during heavy work, exercise, cleaning, or activities that could cause impact or snagging will help protect its setting and finish.
