Diamond Necklace. Avril’s been noticed out and about with a massive new diamond necklace, and turns out, it truly is a reward from her rumored boyfriend. According to TMZ, Tyga gifted the «Sk8er Boi» singer the $eighty,000 customized-produced bling from New York City-based mostly jeweler Eric Mavani. The outlet reports that the chain necklace features fifty carats (!) of white diamonds, black diamonds, and pink sapphires that spell out her very first name, first initial, and two skull and crossbones designs.
