Valentine jewellery suggestions

My boyfriend wants to buy me some jewellery for Valentines but he's totally clueless in this area so I fear him getting the wrong things! What romantic jewellery do others usually prefer for Valentines ? Are there any 'in' items I should suggest/hint to him?
Any help would be appreciated thanks!

I'm a bit late for valentines day advice, but I love the jewellery from Lello.
