Meghan Markle, $200,000
Another royal engagement that made headlines was Megan Markle to Prince Harry in 2017. A custom-made piece, the ring is comprised of a single diamond sourced from Botswana and two smaller gems from Princess Diana’s private collection. The band is made from yellow gold, Markle’s “favorite” according to Harry. After the birth of Archie in 2019, the band was redesigned in a smaller “micro-pave” style. General consensus over the ring’s cost has it priced for roughly $200,000.
