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.

An 8 x 8 mm princess-cut lab grown diamond rises above a simple band in a prong setting, while a discreet round diamond beneath the main stone brings a subtle flash of sparkle to the gallery. With E color, VS1 clarity, and IGI certification, the design is made for engagements, proposals, anniversaries, and commitment milestones where the center diamond should remain the defining feature. IGI Certified 3 Carat Princess Cut Lab Grown Diamond Solitaire Ring The centerpiece is an approximately 3.00 carat princess-cut lab grown diamond measuring about 8 x 8 mm. It is brilliant cut, graded E color and VS1 clarity, and secured in a prong setting. A single round lab grown diamond measuring approximately 1.80 x 1.80 mm sits beneath the center stone in the gallery, bringing the combined diamond weight to approximately 3.03 carats. The confirmed ring is crafted in 92.5 sterling silver and selected yellow or white gold options in 10K, 14K, and 18K with an approximate metal weight of 3.04 grams. What Makes This 3 Carat Princess Cut Diamond Ring Special Approximately 3.00 carat princess-cut lab grown diamond center stone. Center diamond measures approximately 8 x 8 mm. IGI-certified center diamond. E color and VS1 clarity. Brilliant-cut lab grown diamonds. Prong-set center stone. One discreet round lab grown diamond beneath the main stone. Approximately 3.03 carats total diamond weight across two stones. Simple band that keeps attention on the princess-cut center. Available in 92.5 sterling silver and selected yellow or white gold options in 10K, 14K, and 18K construction. The square princess shape creates a defined, contemporary focal point, while the clean band preserves the visual impact of the 8 mm center diamond. The small round diamond beneath the main stone adds detail from the side without changing the ring's center-stone-focused solitaire character. Meaning Behind a Princess Cut Lab Grown Diamond Engagement Ring The princess cut combines a geometric square outline with strong brilliance, making it a compelling choice for someone who favors structure without sacrificing sparkle. In this design, the substantial 3 carat center stone carries the visual focus of the commitment, while the understated gallery diamond adds a detail that reveals itself from another angle. The result suits proposals and milestones that call for a clean, confident engagement ring with a modern silhouette. IGI Certified Lab Grown Diamond Craftsmanship & Authenticity The 3 carat E-VS1 center diamond is certified by IGI, providing independent documentation of its stated characteristics. Rosec Jewels crafts the ring with attention to princess-cut alignment, prong security, gallery-stone placement, and refined finishing, and offers a Certificate of Authenticity with the jewelry for added purchase confidence. Each piece goes through stone inspection, setting security review, and finishing inspection before dispatch, with care guidance provided to support responsible long-term wear. 3 Carat Princess Diamond Engagement Ring for Proposals & Everyday Wear The 8 x 8 mm princess diamond creates strong finger presence from above, while the hidden round diamond adds an extra point of brilliance when the ring is viewed from the side. Its streamlined band pairs easily with understated earrings, bracelets, or compatible wedding bands while keeping the center stone prominent. The ring is offered in US sizes 3 through 13, including quarter-size increments.
