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.

A vivid green center diamond commands attention in a solitaire-inspired prong setting, while spaced white lab grown diamond accents bring light to the band without competing with the center stone. IGI certification adds confidence to a design created for couples who want diamond brilliance with a distinctive expression of commitment. 4 Carat Cushion Cut Lab Grown Green Diamond Solitaire Engagement Ring The centerpiece is an approximately 4.00 carat cushion-shaped lab grown green diamond measuring about 9 x 9 mm. Brilliant cut faceting, Vivid Green color, and VS1 clarity give the IGI-certified center stone its defining character. Eight round brilliant-cut lab grown white diamonds add approximately 0.32 carat of spaced accents, graded E-F color and VS clarity. Both the center and accent diamonds are prong set, and the confirmed ring is crafted in 92.5 sterling silver with an approximate metal weight of 2.72 grams. What Makes This 4 Carat Green Diamond Engagement Ring Special Approximately 4.00 carat lab grown green diamond as the dominant center stone. Cushion shape measuring approximately 9 x 9 mm with brilliant-cut faceting. Vivid Green color and VS1 clarity for the IGI-certified center diamond. Eight round lab grown white diamond accents totaling approximately 0.32 carat. E-F color and VS clarity accent diamonds for bright contrast around the green center. Prong settings secure both the cushion-cut center and round diamond accents. Solitaire-inspired profile with spaced side stones rather than a continuous pavé band. Available in 92.5 sterling silver and selected yellow or white gold options in 10K, 14K, and 18K with an approximate metal weight of 2.72 grams. Why Choose a Cushion Cut Green Diamond Solitaire Ring The 9 x 9 mm cushion center gives the ring strong face-up presence, while its softened corners balance the bold scale of the 4 carat stone. Spaced white diamonds introduce contrast and sparkle yet preserve the green diamond as the unmistakable focal point. Green can evoke growth, renewal, and new beginnings, giving the color natural relevance to a proposal and the start of a shared future. For someone who wants a commitment ring that feels more individual than a traditional colorless solitaire, this design offers a vivid alternative without losing the recognizable engagement-ring silhouette. IGI Certified Lab Grown Green Diamond Craftsmanship & Authenticity The 4 carat cushion cut lab grown green diamond is IGI certified, supporting confidence in its laboratory-grown origin and grading details. Rosec Jewels also offers a Certificate of Authenticity with its jewelry. The ring is carefully crafted with attention to prong security, balanced side-stone placement, and refined finishing, with stone inspection, setting security review, and finishing inspection completed before dispatch. Care guidance further helps support responsible long-term ownership. Styling a Cushion Cut Green Diamond Engagement Ring From above, the large cushion-cut green diamond creates an immediate focal point, while the eight spaced round accents add flashes of white brilliance along the shoulders. The sterling silver setting provides a cool-toned backdrop that keeps the Vivid Green center visually crisp. Designed for proposal and engagement wear, it can also mark an anniversary or major relationship milestone, and its distinctive color makes it especially suited to someone who prefers expressive fine jewelry over a conventional white diamond look.
