This year I'm celebrating our 7th year anniversary and we had a huge milestone (baby daughter) with a birth this year. I was thinking of the Tiffany Soleste Pendant with the Aquamarine gemstone and diamonds since my wife's birth month is (diamond) and my daughter is aquamarine. I was hoping this would be a piece I could pass down to my daughter when she's older. Are there any other pieces I should consider? Would this be a good gift?? Thank you.
