Lady Gaga, $400,000
Gaga was originally given a 6-carat heart-shaped diamond in 2015 by Taylor Kinney estimated to be worth $400,000 before their break-up in 2016. The “Bad Romance” singer then wore this 6 – 7-carat pink sapphire surrounded by a diamond halo worth roughly the same, which was given to her by her next fiancé Christian Carino, although they also broke up early in 2019. Similar styles are being offered on Brilliant Earth from $1,500 – $3,800.
