I must say I am a sucker for personalised & monogrammed jewelry. You see, I have a rather uncommon name which means that I never find anything personalised. However, with jewelry they tend to personalise it for you, which in my eyes makes it special and it also means they can write my name.
Lauren Klein has a range of personalised jewelry and they are all sold at below the recommended retail price, so I think they are worth a look. I particularly like Rose Gold and Diamond Clover Monogram Necklace as pictured below and it is being sold at less than half the RRP!
