“Rose #3” (also known as DarkRose #3) is the next progressive color code in the manufacturer grading system for lab-created synthetic corundum.
While Rose #2 yields a soft, light pastel pink, Rose #3 provides a visibly richer, deeper reddish-pink or dark rose hue. Like its lighter counterpart, it is grown via the Verneuil (Flame Fusion) manufacturing method to replicate the chemical and structural properties of natural pink sapphires and rubies.
