Mom jewelry has always been very popular. It's such a sweet way to celebrate a new mom or to commemorate the birth of a child. One lucky Project Nursery reader will win Dalla Nonna's signature Calendar Necklace. Dalla Nonna's calendar necklace was derived from an old tie pin of the creator's grandfather. The piece is executed in sterling silver (with dimensions of about 1"x3/4", suspended on an 18" chain and accented with a sapphire in the color chosen by the wearer to commemorate a special date. Of course, the obvious choice would be to select the birth date of your child, but I also think it would be super cute to wear while pregnant with your due date on it. What a fun way to answer the question you hear so many times as a pregnant mama! WIN IT! One Project Nursery reader will win the Dalla Nonna Calendar Necklace in sterling silver marking the day of your choice ($150 value). The winner can select the finish (matte or shiny), the month, the day and the sapphire color. Note that because all calendar pieces are custom made to order, they ship 3-6 weeks from the day the order is received.
