Deep azure allure meets striking geometry in this Fancy Blue Marquise & Tapered Baguette three stone engagement ring. The 3 carat fancy blue marquise center (14x7mm) delivers a mesmerizing sapphire-like depth with the unmatched fire and durability that only a diamond provides. Its dramatic elongated form creates a bold presence on the hand, flanked by two tapered baguette side stones totaling 0.75 carats that add angular precision to the deep blue center’s oceanic glow. Together they total ~3.75 CTW of extraordinary brilliance. The cool blue tone is stunning against white gold or platinum, though it creates a striking modern contrast in rose gold. Mounted on a 3.0mm band in 10K, 14K, 18K solid gold or platinum, each diamond is IGI® or GIA® certified, reflecting Mohana Jewels’ 30+ years of heritage in creating exceptional colored diamond jewelry.
