Princess Kate Ring Stack Composition and Key Pieces
The Princess Kate ring stack is publicly documented as a combination of several rings worn together, with the central piece being the sapphire and diamond engagement ring originally given by Prince William in 2010. The ring features a 12-carat Ceylon sapphire surrounded by 14 solitaire diamonds in a platinum setting, a design widely attributed to the House of Garrard, the Crown Jeweler at the time. Additional rings in the stack include a thin diamond eternity band and other stacking rings that Kate has been seen wearing in official portraits and public engagements, with the overall stack emphasizing a coordinated platinum and white-gold aesthetic. The exact carat weights and origins of the secondary stacking rings have not been officially disclosed, though jewelry analysts note the consistent use of high-clarity diamonds and platinum settings across the collection Forbes.
Gemstone and Metal Details
The sapphire at the center of the stack is a Burmese-origin Ceylon sapphire, a detail confirmed by multiple gemological assessments and widely reported by the jewelry industry. The stone is surrounded by a halo of round brilliant-cut diamonds, with the total diamond weight estimated by independent gemologists at approximately 2.5 carats for the halo and side stones. The platinum setting is a classic cathedral style with four prongs holding the sapphire, a design that prioritizes security and light entry to maximize the stone's blue brilliance. The stacking rings that accompany the central piece are predominantly platinum and white gold, featuring both diamond pavé and plain band designs that create a layered, modern look while maintaining a cohesive metallic finish across the entire stack Gemological Institute of America.
