Before becoming a global power couple, Beyoncé and Jay-Z navigated the early stages of their relationship away from the limelight. The commitment was sealed with an 18-carat flawless octagonal-cut diamond set in a platinum split shank band, valued at $5 million. Designed by Lorraine Schwartz, the ring is fitting for someone of her caliber in the entertainment world.

This symbol of their love is noteworthy not just for its staggering price but also for representing their bond, blending timeless elegance with modern luxury. Their private wedding ceremony in New York City marked the beginning of their journey as a married couple, further solidifying their status as entertainment royalty.
