Djeva's #4 neon pink/red ruby exudes an intense neon hue that even in low-light environments, radiates a glowing red. Unlike some pigeon blood color rubies that may appear to have black extinction in dim settings, Djeva's Ruby #4 maintains its vibrant luster. It stands as one of our most cherished materials.
