Jade

Jade is a gem name, and is simply the word for the precious stone used as a given name. Gem names, such as Ruby, were quite popular in the late 19th and early 20th centuries. Jade was not part of this trend, because "jade" was also a slang term used as a synonym for a floozy or hussy, and also a slang term used for a worn out horse--a nag. Jade only really began to be used popularly as a given name after Mick Jagger's daughter, Jade, was so named, in the early 1970's. Since then, Jade has been a fairly popular name in the U.S., mostly given to girls, but given to boys often enough to have made the top 1000 occasionally since the 1970's. Jade (for girls) has been even more popular other English speaking countries in recent years, and has become especially popular in France and Belgium, as well. Jada and Jayda are both names derived from Jade that have lately been gaining popularity.
