Estate Alexandrite Diamond 18K White Gold Bypass Ring, GIA Certified
A striking and sculptural bypass ring featuring two matching oval-shaped alexandrites totaling 2.86 carats, each securely held in elegant four-prong settings. These GIA-certified Indian alexandrites display the celebrated color-change phenomenon that makes this gem so coveted. Under daylight or fluorescent light they appear a rich green; under warm incandescent or candlelight they shift to a deeper reddish or purplish hue—the classic “emerald by day, ruby by night” transformation caused by chromium within the chrysoberyl crystal structure.
The two gemstones are dramatically framed and connected by a continuous pavé of round brilliant diamonds totaling 3.50 carats, which cascade across the swirling bypass design in 18K white gold. The result is a bold, three-dimensional statement that balances the mysterious color play of the alexandrites with brilliant white sparkle.
Currently sized 7.75 and easily resized, the ring weighs a substantial 11.1 grams and is ready to wear. A rare and glamorous piece that transforms with every lighting change—perfect for both daytime elegance and evening drama.
