That necklace she is wearing by Cartier looks ridiculous, it's literally a nail around her neck. Nail you build with, not finger nail design.
The bracelet version is nice but just my opinion the necklace is ridiculous. They also start at £12,800 and go up to £40,000. Ugly necklace and even uglier price tag.
Think of the beautiful necklaces you could buy for that money. No taste!
