This lovely heart Tiffany & Co. Elsa Peretti heart necklace has been worn but is as precious as ever for someone to wear happily. It is Sterling Silver 925 like Tiffany & Co. makes perfectly pure for years. I wanted this when my mother was alive. I bought it and wore it fondly. I asked my 17 year old daughter if she wanted it but she said no. Decided to sell it to help her to pay a student enrollment fee and help my son with some funds for an apartment even.
