Rihanna's Rocking Rocks

According to OK Magazine, Rihanna's going to be blinging the charts soon. Her rumored boyfriend Chris Brown has apparently given his sweetie a ruby and diamond necklace worth a cool $100,000.

Beverly-Hills based jewelry designer Jason Arasheben told the mag that 'Chris went for the heart theme. He said, 'She's going to love this because she loves hearts.'

Rihanna is apparently returning the favor, ordering from the swanky jeweler a diamond-encrusted cross for Chris . The jeweler, not one for keeping quiet about his customers, also told the gossip mag that the singer 'gave specific instructions about Chris' gift. She was very particular about wanting the cross to match his other jewelry.'
