I have a Helen Ficalora necklace and LOVE it. It sees far more wear than all of my other necklaces. The quality is great and I love that you can add to it. Originally I started out with just the letter "A" (my initial) and a dogwood charm with a tiny diamond in it. Then, over time my husband's initial was added. After my son was born my in-laws gave me his initial and last Christmas my sister gave me his birthstone (a ruby). I recently also upgraded the chain from a basic yellow gold chain to Helen's DBTY style (It has bezel set diamonds every 2inches). I love being able to change up how I wear it. Sometimes I layer it, sometimes I wear all of the charms, and other times I wear just my son's charms (letter and birthstone). I also work long 12 hours shifts in a hospital and have children literally TUG on the necklace and have never had issues. When I have another child it will be quite the crowded necklace but I will love it even more.
Here it is the day I first got it

Here's how it looks now: (3 alphabet charms, 1 dogwood, 1 birth jewel on a DBTY chain....all by Helen Ficalora)
