3.00Ct Elongated Cushion Cut Lab-Grown Diamond Trilogy Engagement Ring, Cathedral, 18K Rose Gold

This elongated cushion cut lab-grown diamond trilogy engagement ring features a 3.00 carat center diamond measuring approximately 9.5 × 7.5 mm, accompanied by two round cut lab-grown diamond side stones totaling approximately 0.50 carats. The trilogy setting creates a structured three-stone profile, while a petal-inspired gallery detail beneath the center diamond adds refined architectural design. A cathedral setting elevates the stones and provides additional support for long-term wear. Crafted in solid gold, the ring is available in 10K, 14K, or 18K gold with white gold, yellow gold, and rose gold color options. The slim 1.8 mm comfort-fit band offers a clean and balanced silhouette. An IGI grading certificate is included with the center diamond. Offered in US ring sizes 3 through 12, this lab-grown diamond engagement ring reflects modern fine jewelry craftsmanship and precise detailing.
