Can I add our engagement date on our matching Valentine's name necklaces?

Why not! I am sure she will be just over the moon with such a touching gift. It definitely will be a sentimental gesture for an important day in your lives, and she might even want to wear it on your wedding day. Choosing a gift like this is a lovely way to start new memories that you share with each other. There are some lovely gold necklace options on Myka, that accommodates names and dates, such as interlocking hearts necklaces, for example.
