Bague de fiançailles en diamant coussin bleu fantaisie Old Mine

This blue lab grown diamond ring features a rare and romantic old mine cushion cut diamond ring design, showcasing a bold 3 carat diamond engagement ring center stone in a stunning elongated silhouette. The blue diamond cushion cut engagement ring is crafted with a 3 carat old mine cut diamond of blue elongated cushion shaped brilliance, also known as a pillow-shaped diamond, giving the ring a soft, vintage-inspired look with a modern colored diamond twist. Blue diamonds are often chosen to represent loyalty, trust, and sincerity, making this colored diamond engagement ring a meaningful symbol of a deep, lasting bond and best complement cool skin tones, which are characterized by blue or purple veins and undertones of pink, red, or blue.

The center elongated cushion cut engagement ring is secured in a 4 claw prong setting and elevated with a basket setting engagement ring structure. This basket style creates a protective “cage” around the pavilion, improving stability and durability while still allowing light to enter from multiple angles. Even though it gives the look of a high profile engagement ring with plain band, the basket design helps reduce snagging and provides extra comfort for daily wear compared to standard high-prong styles. Blue lab diamond set in white gold represents a modern, luxurious, and highly aesthetic pairing that symbolizes deep, tranquil love, loyalty, and individuality

To enhance the center diamond, marquise shaped diamonds and round diamonds are set in round prongs setting, creating a balanced side-stone layout that frames the cushion cut beautifully. The ring includes 0.4 carat diamond TCW of marquise cut lab grown diamonds and 0.2 carat diamond TCW of round lab grown diamonds, paired with a clean plain 2mm band engagement ring for a sleek finish. With its old-world charm and bold blue color, this elongated cushion diamond engagement ring is ideal for anyone looking for a statement piece that still feels classic and wearable.
