However, Kate, 42, chose not to wear her 12-carat oval Ceylon sapphire, surrounded by a cluster of 14 solitaire diamonds in white gold.

The late Princess Diana chose the ring when she was presented with a selection of options by then-crown jeweler Garrard of Mayfair as part of her engagement to then-Crown Prince Charles.

The mother of three instead opted for a thin gold ring, topped by what some speculate is a new “eternity ring.”

Kate wore the diamond and sapphire accessory in August while filming a Team GB video with William and during their heartwarming family video released last month.

Tobias Kormind, co-founder and managing director of 77 Diamonds, Europe’s largest online diamond jeweler, told GB News that the new ring is likely to be an “eternity ring” meant to symbolize William and Kate’s love.

He continued: “Kate’s new ring could be a symbol of hope for a new beginning, with an emotional connection to the past.”
