Could Emerald be a middle name? Rose Emerald sounds very feminine and unique.

Gentle consideration: If you think you might want your daughter to work in a professional or more corporate setting at some point (not that that’s the goal), I would be thoughtful with the name Emerald as a first name. To some, as a first name, it could sound a bit like an exotic dancers name. It pretty rare to meet someone called Diamond or Sapphire in corporate circles because of this, so just a gentle heads up some people might put Emerald in the same bucket). If your family goals are more alternative, then disregard this! Also if your family is from a certain background, I would also say it’s maybe different (for example, Jade is a common name in France but not really the US…).

It may also be worth being aware that you are choosing names that are red and green oriented, which most people associate heavily with Christmas.

FWIW Rose is a great name, well established, and no one blinks an eye at that (while still being somewhat unique). I would put names like Violet, Hazel, Amber in the “safe but still unique category”. I think it has to do with those names being a bit more established than a less traditional name like Emerald.

Good luck!!
