Katy Perry, $50,000
The “I Kissed a Girl” singer received her own “precious” ring from “Lord of the Rings” actor Orlando Bloom on Valentine’s Day. Designed in the shape of a flower, the ruby stone is surrounded by equally stunning diamonds. For those looking to wear one of these botanical beauties, the price ranges from $8,000 to $32,000. Although, some eagle-eyed jewelry experts question if the center stone is a ruby or a pink diamond, which would make the ring several times more valuable.
