Brazilian Alexandrite & Diamond Engagement Ring in Platinum

A rare and captivating engagement ring, this platinum design centers on a Brazilian alexandrite, celebrated for its remarkable color-change phenomenon. The cushion-cut gemstone shifts from a soft green in daylight to deeper, warmer tones under incandescent light, giving the piece a dynamic, ever-changing beauty. Flanked by tapered baguette and round diamond accents, the setting enhances the center stone with clean, architectural lines and balanced brilliance. Crafted in platinum, the design feels both timeless and refined, with a crisp, elegant silhouette that highlights the rarity of the alexandrite. Distinctive and collectible, this ring offers a sophisticated alternative to traditional engagement styles, combining rarity, craftsmanship, and understated glamour.
