And, according to Dailymail.com, Sharapova received a £300,000 five-carat emerald cut diamond engagement ring to mark the special day.
The Jessica McCormack-designed ring is in rose gold with the huge diamond sitting centrally.
The pricey ring will put most sporting wags’ versions to shame – but not Georgina Rodriguez.
Cristiano Ronaldo is believed to have presented his stunning partner with a cartier diamond ring worth £615,000.
Sharapova and Gilkes kept their relationship quiet until the Russian beauty revealed images of a romantic trip to the Cotswolds in October 2018.
It is believed they initially met in January earlier that year but opted to keep a low profile.
Gilkes, 41, is a millionaire businessman, co-founder and president of the Paddle8 online auction house.
He is also the ex-husband to Meghan Markle’s best friend Misha Nonoo who helped the Duke and Duchess of Sussex get together.
