I believe these are part of the Valentine's collection of Spring 2007Hi, I just received them and I do not see any engravings on the side of the earrings. I’ve seen this exact style sold on other reputable places in either a pink or black color like this pair. The seller told me she had purchased them at a boutique in the UK and was told they were authentic as well. Do you happen to know what year these earrings are from? Thanks so much for your help!
