The name Crystal is a girl's name . Crystal is ranked #644 on our popularity charts and is often added to lists like Jewel and Gemstone Baby Names and discussed in our forums with posts like "Girls Makeover - Two Middles".
From the experts:
Peaking at #9 in 1982, Crystal's popularity in the 70s and 80s stems from its sparkling natural namesake and several notable bearers, like country music singer Crystal Gayle and Dynasty character Krystle Carrington. But it has since lost some of its luster for American parents, now ranking in the mid-600s. Ruby, Gemma and Pearl are fashionable alternatives, but nowadays Crystal could actually be a more unexpected choice for your little gem.
